I updated some stuff for tromjaro.com/ homepage to reflect the latest changes to TROMjaro. Had to record again a bunch of videos and such. But I think is worth it. Looks great! For example the laptop slider we have there, that showcases the wallpapers we use, now allows you to click any wallpaper and download in full resolution. From now on I plan to make a bunch of tutorials about a bunch of things TROMjaro related ;) and post them on the forum ofc.
I went to the museum today. Actually to two of them, in Barcelona. Very nice. Science museums of course. I am blown away by the diversity of creatures that are on this planet or have been. Look at this motherfucker - an elephant with a big tooth or lip whatever that is. Never saw that before:
It looks like is not real....
Anyway, tomorrow I am getting back to work on TROM II if nothing odd happens to the Kdenlive project...I will also share new sources for TROMjaro and TROM files downloads. So that you can grab our files from yet another reliable location. Speaking of that I am almost done with the online backups :D . Feels so great! I am so happy we can backup all of our files online too. Such a relief. #tromlive
It is this bad boy en.wikipedia.org/wiki/Platybel… - I had no clue this creature existed. Looks like a joke or a blender render without any reality context. haha
We have released a new TROMjaro ISO, actually 2! We are releasing in two flavors from now on: Modern and Classic. See the release notes forum.tromjaro.com/t/tromjaro-…
With this release we are moving closer to getting TROMjaro XFCE out of Beta. And for that reason we are releasing two versions. Let me explain the “them” and the “why”. TROMjaro Modern. TROMjaro Modern is similar to our original TROMjaro Gnome.
@Alexio has a lot of trade-free services for everyone status.alexio.tf/status - similar to trom.tf. Universe bless his soul! Such a great human and always there helping with TROM stuff. #tromlive
Not all is nice and dandy with linux+xfce. XFCE is really great, but on my laptop (having Nvidia) my TROMjaro crashes every 2 or so days to the point of no return. I have to manually shut it down from the button. No TTY working. That's a super duper bad bug. :(
Especially when you work on a multi hour and massive documentary, while at the same time I may build a new tromjaro ISO, have so many projects, emails, millions of files to sync...it is a disaster.
It is not linux or xfce's fault, but nvidia or other manufacturers that do not provide proper support for their hardware. Same tromjaro works perfectly fine on other laptops I am testing.
Then it might depend on the distro. I am running Manjaro myself and I know there are problems with Wayland and Gnome. Maybe there are some underlying issues that is not know yet. Maybe it even depends on the type of Nvidia cards being used.
Very likely an issue with the Nvidia card I am using. The driver probably is buggy for my graphics card. But only with XFCE it seems. Worked well with Gnome....
Ah, suppose it will have a problem with the graph libs in xfce then. I am using Gnome and it works well indeed. Did not test any other WM yet with this card ( NVIDIA GeForce RTX 2060/PCIe/SSE2 )
Not even being able to access the TTY sucks, that's a nasty bug. I hope Linux improves in these areas. Even though I personally use linux, I find it a bit hard to recommend it to noobs because of these stability/consistency issues. I'm not really satisfied with any of the noob friendly GUI distros I've tried so far.
I get that, but these errors are rare. Most of the bugs are not that bad. I used Windows for many years and came across some very nasty bugs...in high-school I was the "computer guy" who repaired broken windows computers and had to reinstall so many and deal with so many bugs.
Yeah, this is an interesting perspective, because I think all OSes suck and have nasty bugs, not just linux. And you probably would've seen more windows bugs than most people since you were the "windows repair guy", haha. TBH, I haven't used windows for that long so I'm more familiar with linux, and all the time I did use windows was just watching movies and stuff, I didn't really did much on it.
Syncing several million files to the cloud for backup, a total of some 8TB, takes a while...not because of the speeds, but the so many files that are constantly updated. 7.3TB so far but sill a few hundred thousands files left to upload. They also get encrypted while they are uploaded so takes a little bit more than usual. But most files are already there, safe. Thanks to the people who donated money to TROM and allowed me to buy enough online storage space to backup everything to the cloud too. #tromlive
So I am kinda done with the first part of TROM II documentary. 1h 5min long. I still have to tweak a few things here and there but in a few days I should be entirely done. That's great! :) #tromlive
A trade-free video hosting platform for science/technology/nature videos in the English language. You do not have to trade your currency, data, attention, freedom or anything else, in order to use it.
If you don't read this post on Friendica (why!?) then make sure you read it in full here. So you see the images, links, and all that.
This is a chart with COVID vaccines vs mortality due to COVID per million people. Left side is how much of the population is fully vaccinated. Right side the mortality rate.
It is quite clear that the more people are vaccinated, the less are dying of COVID. Now there is a new variant of concern - read the WHO statement about it news.un.org/en/story/2021/11/1…
Of course, it comes from Africa where the vaccination rate is very low. What are the tribes of the world thinking? This was very predictable. Delta came from India from the same reasons, and now Omicron is thought to be even more dangerous. If we have global problems but we only act locally, this is going to always happen.
When people doubt the institutions and companies, and in many cases for good reasons, then trust is eroded. The trade game that we play creates this situation, since companies and governments seek profits that are induced by the game of trade itself, so they cut corners, lie, are corrupted, and overall care more about profiting than they do about humans and the planet.
So the trust is eroded, and people are skeptical about the vaccines, and thus the vaccination rate will be lower even when there are vaccines available. This is why, even the new variant, is discovered mostly among unvaccinated people (source). Also the mortality rate that is seen in the world, due to COVID, is mostly among those who are not vaccinated. Therefore, even where the vaccine is available, people's mistrust in this society, couple with the bullshit of social (ad) platforms like facebook, twitter, youtube and the like that spread any nonsense that gets clicks, creates a disastrous situation.
SECOND. Poor tribes do not get access to vaccines, so they become a breeding ground for new mutations of the virus. The vaccines should be open source and free for all. There are 0 excuses for this!
The moral of the story is that we are a global society that has global problems, from crime to climate change, from pandemics to starvation or waste and pollution. And yet humans act as if the imaginary borders they built, are going to protect them from such global threats.
Unless we wake up, and also give up to this primitive idea of trade that creates so many barriers, nothing will ever ever change.
Such a situation would be so different in a sane society: - most people would have at least their basic needs met as trade-free, so they will have time to be more informed, relaxed, and cooperative in case of such an emergency - more people could focus on solving the issue (doctors, researchers, citizen scientists) - once a solution is found, will be distributed to those in most need, not in most rich tribes, thus preventing deaths and future mutations of such a virus
We act like retarded children. But this behavior comes from the environment that we are exposed to. Never forger that.
Thanks to the amazingness of Frendica, I created a new profile that auto posts from Reddit, from the most awesome subreddits about nature. Basically I created an RSS feed via rss.trom.tf then a Friendica account that mirrors that RSS. There it is: social.trom.tf/profile/brp
Anyone on the Fediverse can now follow it! #tromlive
Yah....so since Friendica is also an RSS Reader, then is so awesome you can follow any website basically. And since they allow to repost from any account, then I can setup a Friendica page that takes the RSS I just created, and shares its posts as its own. Super cool. Friendica is very underrated.
The media in this post is not displayed to visitors. To view it, please go to the original post.
So now this account started federating with my instance and I can see its posts. But unfortunately, I can't see the images without going to a link which opens the same post inside a browser. IDK why friendica works this way, its very strange.
It's time for you to move to feature-full friendica! :) idk on Friendica it simply works...it is likely an issue with Mastodon. Can you ping your Mastodon admin about this?

So now this account started federating with my instance and I can see its posts. But unfortunately, I can't see the images without going to a link which opens the same post inside a browser.
Not sure. There's nothing that we do specifically here on Fosstodon in federating with Friendica. When I look at the feed, I'm just seeing a list of links, not the content of the posts. I'd wager it's something to do with how Friendica is federating, but that would just be a guess. When I look at the account from a test account I have on another instance, it's telling me "old" posts aren't available. The @tio shows text in the posts, but links at the bottom of those as well
It isn’t specific to Fosstodon, this account will show the same way from all Mastodon instances. This display is the result of the way Mastodon chooses to display specific ActivityPub object types. Assuming its role as a microblogging platform, it probably chooses not to display the content of “Article” objects because it is expected to be longer than a “Note” for example.
Thanks for the info, it makes more sense now. Is there any way @tio could make it a normal post and not an article type one ? Its mostly just pictures with a small caption, so its better seen as a normal post on mastodon.
I believe the way we separate Articles from Notes is whether the original source has a title. And since RSS/Atom entries all set a title (possibly per protocol), these posts will always end up as Articles, no matter how short the body is. Nothing @Tio can do about that, unfortunately.
I am working on some tweaks for TROMjaro to fix some inconsistencies and make it a lot more stable and sane. The layout may change, mind you, but you'll see. All for the better. The changes are not big at all, but important enough to make it a lot lot saner and more consistent. After all we want a TROMjaro that is very fast, very stable, very easy to use. i will post more updates these days about it and the reasoning behind it. Waiting for some feedback and testing from our small TROMjaro crew :). #tromlive
I already do local backups so this is not a must. But it would be fantastic to be able to also back up the stuff somewhere else. If this house burns down I lose most of my files. Including all of the TROM II documentary. I also do not have money to pay for this myself since I need to save as much money as possible.
These backups are for all of the stuff/servers we have, including trom.tf and the files that people store there (think nextcloud, friendica, peertube). Please, if you can, help out. :)
200 Euros is not a huge amount of money, so maybe we can raise it! :D
hahhaa that was exactly my thinking of course, if the house burns down I have other problems on my hand. But considering it is a rented house it is a temporary lose, while all of the 10 years of work that I have stored on my hard drives is quite valuable and non-recoverable to me :D
I toasted my computer yesterday....trying to build some local packages for TROMjaro. I think the scripts from those packages deleted parts of the system...idk... Tried to restore with timeshift but it has a bug with encrypted disks....so I could not restore the boot on the main encrypted drive. Struggled for a few hours, then finally did it. Luckily I have lots of backups and even my system backups are on a separate drive.
Now I am setting up cloud backups too, for my most important files for now. Tried s3 object storage and am so confused and seems to cost a lot. Managed to easily connect to my nextcloud account (files.trom.tf) so that I am managing it via this account, plus I get full encryption. But after syncing some 1k files out of 1 million, I realized it is fucking expensive and hard to calculate how much it would cost.
At least I tried it for when we will need it to expand our peertube storage...
So I looked a lot and a lot. To find a cheap solution that doesn't ask me how many files I upload and how often. The cheapest I found is

So I looked a lot and a lot. To find a cheap solution that doesn't ask me how many files I upload and how often. The cheapest I found is mega.nz - for like 5 Euros for 400GB, but can extend to 2TB for just 10 Euros, and 8TB for 20 Euros. Has end to end encryption and only a monthly bandwidth limit.
For example with object storage you even pay when files are requested. So say I use nextcloud to do the backups. Now nextcloud gets the files from my computer and sends to the object storage location, but nextcloud also indexes the files, that means it asks the object storage how many files there are and such. And I get charged for that. Considering I want to backup several million files, this is not cheap.
Anyways, I want to maybe have my files somewhere in the cloud too. Nextcloud is an amazing alternative but the only downside for me is storage. I either buy a storage VPS or attach some object storage solutions to nextcloud. None is cheaper than Mega. They can be 5 times the price.
Anyway....I have to take care of my files. I have so many projects and such. #tromlive
I want to release a new TROMjaro iso but the latest Manjaro updates broke a few things so I have to fix them:
the top panel custom launcher icons are black on a dark background....this is easy to fix but I'd like to know why this happened; it is not manjaro's fault probably, but the icon pack we are using
the packages we use for the global menu and HUD got removed from manjaro's repos so I'll have to package them myself for our own repo, and at least 1 of these packages fails to build
On top of this the gnome-schedule that I was using to do some cron tasks doesn't work anymore so I can't automatically do the server backups....that very much bothers me....I need to find a solution for this asap. else I have to do them manually.
We also plan to ship TROMjaro with the global menus disabled. Basically to let the default window be container, with the top bar and menus and all that. Since this is the most stable way to do it. And users can then enable the "window expansion" so when you maximize a win

Did a lot of work on TROM II today. Now we are at 1h and some 2 minutes. Happy with the result. May take a break the entire day I want to go out with the telescope a bit tonight, to see some wonders of the solar system, and another wonder that's outside. The closest galaxy, Andromeda. 2.5 million light years away. You can spot that with a decent telescope so am excited to see it again.!
I think I will finish this first part of TROM II in just a few days. Pretty sure! Then I will start a new part, and idk how long that'll be. Will see... #tromlive
Shut’up. I know, ‘am no physicist. And no scientist for that matter. That’s fine. I just had an idea and is likely to be wrong but it makes my brain giggle with curiosity.
Read the post. I just solved the black holes and dark matter mystery. hahaha #tromlive
Shut'up. I know, 'am no physicist. And no scientist for that matter. That's fine. I just had an idea and is likely to be wrong but it makes my brain giggle with curiosity.
Well they call it a hole...I know is not like a normal hole. But as far as I understand it doesn't spew what it swallows somewhere else since you can see it growing and account for the stuff it swallows. The Hawking radiation is simply a proof that they also lose "stuff". Stuff gets out. And probably that's normal matter since we can "see" it.
"It just pulls everything in to the singularity" - so you're saying it pulls stuff into that "point"? Then why are these black holes bigger, smaller, have a shape, a mass? I don't get it :D
Yeah, time is just a way for us to measure change. I remember Jacque talking about this in the TROM documentary, sun didn't rise because its 6:00am, its actually the other way around. We get stuck in this mentality of seeing measurement as the thing you're measuring.
I think your way of looking at it might me more accurate. Its not time slowing down, its just rate of change of atoms or something that changes, that's usually what we mean when we say time slows down.
Yeah, its fun to think about stuff like this, I used to do that all the time. But without doing the actuall science, all we do is kinda like a philosophical pondering of the endless possibilities, its still fun though 🙂 @tychosoft
"It just pulls everything in to the singularity" - so you're saying it pulls stuff into that "point"? Then why are these black holes bigger, smaller, have a shape, a mass?
I'm no expert, but from what I understand, what they mean by the size is the event horizon. The event horizon is a boundary inside which light can no longer escape. So intuitively, this event horizon should expand when the mass increases because gravity increases with mass.
It is very much associated with the field "philosophy". Which I hate since it is a lot of bla bla bla. You can't murder every interesting conversation by calling it philosophy haha. It is simply an interesting conversation. I don't want to talk about reason, and logic, and nonsense concepts :D - i am just allergic to that word.
We try to categorize things into different topics. This is sometimes helpful, like if someone said they're interested in physics and someone else is interested in chemistry, we'll have a rough idea of what they mean. But often times we can't really categorize everything into one or the other. Like asking if a hyena is a dog or a cat ? We invented these words like cat & dog, they're not real. @tychosoft
I don't know if it should be called philosophy, but there should be a word for things that cannot be disproved, but can't really be proved either. There are people who argue that free will is an illusion, and some others say we might be living in a simulation. There's no way to disprove these theories, we can only just ponder about them.
"Problem of other minds" is a perfect example of this, since there's no way to prove/disprove it. This is similar to the question "Is your red the same as my red?", Vsauce did a video about this problem - youtube.com/watch?v=evQsOFQju0…
You're right, these might be a bit "bla bla bla", its still quite interesting to think about. They really show us our limitations, we can't know the answer to everything.
Yes but philosophy means very much nothing of essence. And we talk about categorizing not animals and such, but discussions, which is even more abstract. It is great to think and come up with ideas about whatever you like, but to make a "category" out of these is too much for my personal comfort. I do not think it helps :P .
Yup very good video. Explains very well. However considering that it is is difficult to understand these monsters even my theory may end up being correct haha. In the end doesn't matter at all, what matters is that these exist and are mind blowing.
Yeah, maybe trying to categorize discussions is not that great. There are times where these could be useful, like the example of physics & chemistry, but it doesn't mean anything other than a rough idea of what we're talking about.
I don't know if there's any reason to be against the field of philosophy, that Vsause video I sent you earlier is pretty philosophical, but I can't say I never learned anything from it :) @tychosoft
Well I had several discussions with people who studied "philosophy" and they all ended up very badly with them bla bla blaing so much that even they got confused. Maybe my distaste comes form there.
Well we can't observer them, remember!? But we can observe the outer side of them when they have lunch, and we for sure see a disk-like shape. Which can, in fact be spherical.
I've never talked with anyone who've studied philosophy, so I don't know. Because a lot of these are just speculations, I assume a lot of shitty theories might've ended up in this field, haha. But if you talk talk to the right person, I think every field can be interesting ;) @tychosoft
Oh yeah, the singularity might be of any shape, we don't really know much about the inside, everything after the event horizon is just black
Most black holes I've seen in pictures and stuff have a spherical event horizon, and I think the disk you're mentioning is things orbiting these black holes that glow because of their heat, that video explained it. If the event horizon is spherical, the stuff inside should be spherical too right ? I don't know enough about gravitational fields to know
That disk shape could also be something called "gravitational lensing" which happens around the event horizon. Its kinda weird TBH, crazy things start to happen when the gravitational pull is so high !
> Could also be that there is no such thing as singularity...
Could be, but the mass of the black hole still has to exist somewhere inside the event horizon. The idea of a singularity is probably used to explain the extreme gravitational pull, maybe it'll have less space-time curvature if the mass is spread around VS on a densely packed point. So more space-time curvature means more gravity. I'm still not sure how scientifically proven this singularity thing is, this is my understanding.
I think this video explains it well khanacademy.org/science/cosmol… - if am object is much smaller but has the same mass, then an object can get closer so the gravity is much stronger. But now we know that even the black ball, what they call as event horizon , is much smaller than a star. So it is already insanely dense and small. Like crushing multiple stars in a few km round object. Now what they are saying from what I understand from you, is that this mass of a black hole is not that black disk we observe, but a tiny point in the middle. This sounds very insane haha. Might be true tho, but insane. My black ball theory sounds less insane in that regard :D
Thanks for engaging I learned more things because of that. I wsn't aware that they are saying that a black hole is a black nothing but its mass is in a very dense center thats super small. I had the wrong impression that the black hole is the entire black thing. Maybe that's what made me think about it being a black ball. These two videos explain it well:
Although I will have to update my theory ( :)) ) it still may be wrong the way they are theorizing about it now. Maybe there's still a black ball instead of a black hole, and it is made of a different type of matter, maybe even dark matter.
You did great at explaining this, and I am very happy you have engaged in such a discussion :).
But if you think about it, size does make a difference. If you're falling into a 10km size star with 1 tonne mass, you'll experience the same gravitational pull as a 1km size star with the same mass. But remember, gravity increases when distance between you and the star reduces, so you'll keep on accelerating as you move closer to the star. So on a 10km size star, the closest you can get to it is 5km (its radius). But on a 1km size star, you can go up to 0.5km where gravity is stronger 🙂
That video is talking about the same thing I said earlier. So its confirmed, dense objects have higher gravity 🙂
> this mass of a black hole is not that black disk we observe, but a tiny point in the middle.
Of course, the event horizon is not a physical boundary like the boundary of a ball, its a point after which light can no longer escape from the gravity of the black hole. And gravitational field is always much larger than the size of the object, think about sun pulling on earth.
My confusion regarding this black balls theory is this:
1. Not even light can escape a black hole because its so dense that the gravity is in the extremes. But if it was a ball the same size (of event horizon), then it wouldn't be this dense and wouldn't have that much gravity
2. We don't even know if matter can become dark matter, let alone say that stars exploding will cause it. Its called dark matter cause we literally know nothing about it, lol 😂
You replied to the wrong message again, haha. It didn't even tag me.
I wonder if its a bug in friendica or you just accidentally clicking the wrong reply button, this seems to happen from time to time. I don't know how it is in friendica, but if its a bug they gotta fix it soon.
Of course, the event horizon is not a physical boundary like the boundary of a ball, its a point after which light can no longer escape from the gravity of the black hole.
At least thats what they theorize ;)
And gravitational field is always much larger than the size of the object, think about sun pulling on earth.
Same for a black hole, it extends far more than that dark disk (ball).
Not even light can escape a black hole because its so dense that the gravity is in the extremes. But if it was a ball the same size (of event horizon), then it wouldn't be this dense and wouldn't have that much gravity
Actually the one who first came up with this theory, a mathematician some 200 years ago, called it a dark/black star and proved mathematically you can have such a star where light can't escape it because it is so dense. And black holes are actually stars....same way a neutron star is still a star. They call it "hole" and make things confusing a lot :D.
We don't even know if matter can become dark matter, let alone say that stars exploding will cause it. Its called dark matter cause we literally know nothing about it, lol
Exactly. We don't even know if it is matter. But has similar properties with a black hole that's why they are thinking black matter can in fact be black holes. They both do not interact with light/matter so that we can't see them, and have a strong gravitational pull.
I don't know if its just a theory, what's happening inside a black hole we can't know, but we can observe the surroundings to prove that there's extreme gravity there that even light can't escape. Remember, light only moves in a straight line, but massive objects can bend the space-time curvature to bend its path. This has been proven, I recommend you look more into general theory of relativity, its very interesting :)
> Actually the one who first came up with this theory, a mathematician some 200 years ago, called it a dark/black star and proved mathematically you can have such a star
I didn't knew about that, interesting... 🤔 Also, keep in mind that this mathematician can be wrong, there has to be a reason we don't call it a star anymore. Einstein published general relativity in 1915, before that we didn't had a clear picture of how gravity worked.
Its possible for a star's gravity to bend light, this is actually how we proved general relativity. But a star's gravity is not strong enough that even light can't escape, if it were then it wouldn't be able to glow ;)
Also, when you call it a black ball, a dark planet comes to my mind. And I don't get how a planet can do what a black hole does. Even if your black ball was made of dark matter, the gravitational properties would be kinda the same as a normal ball.
hahaahha no no i am familiar with that. but maybe there is a very dense ball from which light can't escape, or maybe it is made out of dark matter and we don0t know wtf that is :).
We call it a blach "hole" because of a movie theater or something like that, which was called the "black hole". About a prison where inmates will go but never come back. Just like matter seems to go inside of these "black stars" and never come back. So the naming was quite random.
A "black hole" is a star. It is a collapsed star, same as a neutron star. So we can better call it a "dark star" or something like that. Now the properties of this dark star can be that its size are immensely small and dense, like the singularity of a black hole. Semantics. A dark star, or black ball like I call it, can be so dense that light can't even escape it. Why can't it be? Or can be that is made out of dark matter and combined with gravity it sucks in normal matter and converts it into dark matter.
A star doesn't have to glow. White dwarfs barely glow.
Take normal matter. A neutron star then the Venus planet. Both made out of normal matter. But the neutron star's gravitational pull is immense compared to the one of the planet Venus. Despite them being made out of the same matter. Why can't it be that dark matter that we observe scattered around the universe clump under tremendous pressures into a ball just like a neutron star, and have immense gravitational pull? :P
I've been thinking about this video you sent me....... And I think I get it now, I understand why they theorized singularity to be a point. This is even more stranger & weirder than I thought, haha.
So when a star dies and it collapses under its own gravity, 3 things can happen. If the repulsion between electrons are able to prevent the collapse, then it becomes a white dwarf. If the repulsion between neutrons stop the collapse, then it becomes a neutron star. But if the star is too massive and even those nuclear forces can't stop the collapse, then there's no other force known to science that can stop it from collapsing on its own. So it collapses into an infinitely dense point !
Just think about that for a moment, this is one of the craziest shit I've ever heard, and its hard to believe these things actually exist ! 😲
Its really hard for me to grasp this concept, because its so different from everything I've experienced in my life. My intuition tells me that if more stuff gets sucked into the black hole, the singularity should get bigger. But it doesn't !
The reason why we can't compress everything into a point in real life is the same reason why I can't push my hand through the wall. The atoms/electrons in my hand repulses the atoms/electrons in the surface of the wall. But inside the black hole, the gravity is so strong that it overcomes these repulsion between atoms, so there's no other force to prevent it from collapsing into a point.
No matter how much stuff you throw into a black hole, the singularity will remain the same size. The mass of the black hole will increase and thus the gravity increases, so the event horizon will get bigger. But the actual size of the singularity won't increase, it'll just collapse everything into that infinitely dense point. This is just insane 🤯
As long as we're talking about the singularity, the name we give to it doesn't matter. In my mind, I see stars as something that radiates energy, so its hard to call black holes a star. I know about hawking radiation, but its very different thing. In hawking radiation, none of the energy/matter that's released comes from the black hole itself.
From wikipedia: "A star is an astronomical object consisting of a luminous spheroid of plasma held together by its own gravity"
Its also hard for me to call singularity a "ball" because now I have a better understanding of why they theorized it to be point sized. Even if it wasn't point sized, I still find it hard to call something so tiny a "ball". Would you call atoms a "ball" ? IDK, sounds weird to me.
About dark matter, there is still the question of where that normal matter went ? If you're saying that normal matter turned into dark matter, then it would work AFAIK. But my question is "why ?". You're just adding an extra step to the whole process, there's no need for matter to become darkmatter for black holes to exist, so why make it more complicated ? 🤷
If scientists are looking into such theories, then they're probably doing it for entirely different reasons than us 😂
Oh ofc, that's how I started the article. I am quite sure I am wrong, but I am also quite sure that science is more than capable of making fun of itself later on in life. So many scientists, the height of academia, thought of aether as a medium through which light travels en.wikipedia.org/wiki/Luminife… and they were so wrong. Or the theory about fire that was making a lot of sense and was accepted by all scientists at the time, yet it was so wrong en.wikipedia.org/wiki/Phlogist…
So considering scientists say that we have almost no clue about what black holes really are, or what dark matter/energy are, then maybe they can be totally wrong. That makes me even more excited :)
Stars do not have to be a "luminous spheroid of plasma", same way that what they call a planet should not necessarily be an object of X size that clears its orbiting path of debris/asteroids. Also, aren't moons same as planets?
I find it impossible to imagine it is a "point sized". What in the world does that mean? haha. Ofc this can be true, but I find this one to be so wild. Much wilder than perhaps it is a "dark star" made out of matter we do not grasp now.
You're just adding an extra step to the whole process, there's no need for matter to become darkmatter for black holes to exist, so why make it more complicated ?
As explained in the article....it can solve 2 issues: 1. We understand what black balls are. And 2. It may explain how dark matter comes into existence.
Why would you invent the singularity (infinite point), or the "event horizon"? These are completely new things. To say that the blackness of a black hole is just stuff that we can't see because light can't escape the gravitational pull, is also an invention, isn't it?
If you're saying tremendous pressure can turn matter into dark matter, yeah it sounds plausible. This would also explain why stuff pulled into the black hole also become dark matter, because one thing that black holes and a collapsing star have in common is pressure ;)
I still have some doubts as to what happens after it turns into dark matter, but considering how little we know about them I don't think there's any point in us arguing over what "might" be happening, lol 😅
I don't think it does, haha. I know its a little hard to understand but that's what makes black holes interesting, its not like anything we've seen before.
Of course I agree that scientists can be wrong. Coming from a scientific guy like you, it makes sense. You know very well where the limits of science are.
Funny story, I've heard this argument from a religious person, saying that science will say one thing today and another thing tomorrow, so its not reliable. I later said to him that where there's change there's progress, so science will keep correcting its mistakes and become better as time goes on, while religion is stuck in the past 🙂
This is actually an interesting question. I think technically they're kinda the same, but we gave them different names just to make communication easier for us.
Yes, you'll find it hard to imagine a point sized object cause its vastly different from anything we've ever seen. I don't know how to explain this, but I'll try. You just have to think about why a point sized object can't exist in our day to day life. If you think about it from the perspective of atoms and particles, then you'll understand that its because of the repulsion between these particles. Black holes are born when stars collapse that are massive enough to overcome all repulsions.
Atoms are spherical shaped and are made of even smaller sub particles, so its not that different from a star/planet (which is made of many small particles as well), atoms are just tiny.
I think of singularity as a point, its more exciting for me that way ;)
And considering how little we know about the universe, maybe the closest we can get to truth is to consider the latest science we know. Ofc, it can always be wrong, but that's just the best we can know from a scientific perspective 🙂
> 2. It may explain how dark matter comes into existence.
I don't understand this point, that's why I asked this question:
> How does this dark matter singularity become that foggy patches shown in the NASA Hubble map ?
The gravity of a black hole is so strong that nothing can escape it, so how can dark matter escape it considering their gravitational properties are similar to normal matter ?
> To say that the blackness of a black hole is just stuff that we can't see because light can't escape the gravitational pull, is also an invention, isn't it?
I don't think its an invention, that's how we define black holes ! (AFAIK, We defined them even before finding one IRL) From Wikipedia: "A black hole is a region of spacetime where gravity is so strong that nothing — no particles or even electromagnetic radiation such as light — can escape from it."
That's what they "suppose" :). I agree that this may be the case, but considering they know very little about these things, speculation is still a toy we can safely play with.
Black holes are born when stars collapse that are massive enough to overcome all repulsions.
That's the theory. But we do not know for sure. Maybe there are all sorts of matter out there and forces. After all the normal physics and the quantum one are still not shaking hands from what I know. They had to invent a new kind of physics to explain those new particles.
Yes but as far as I know sub atomic particles do not "obey" the laws of physics. They had to come up with quantum physics to explain them. A star is different, on a different level. I get your point, but an atom is not a "point" either. And is not round either, of course. It is a wobbly thing with clouds of electrons around them, and a core made out of protons and neutrons.
And I explained: a normal star produces the chemical elements (atoms) we know of today. That means atoms made out of protons, neutrons and electrons. We understand that.
Now the same matter can form a cloud of gas that has a very weak gravitational pull, or under tremendous pressures a more dense object like a planet or a star, or a neutron star.
So, same matter, different "objects": from clouds of gas, to planets, asteroids, or stars of wildly different sizes and densities.
Why can't this be true for dark matter? What if dark matter is made out of different particles (atoms) and in most cases you see it as a sort of "gas" that still has a decent gravitational pull from my understanding, but at times under tremendous pressures it coalesces in the form of a star.
ofc this is pure speculation but an interesting thought experiment.
Yes but that's still not fully demonstrated. It is an idea, that so far has some predictability. But so did so many other theories/ideas. It is a reason why I don't start to say that maybe atoms are just dark matter that absorb light, since we have "touched" the atom and humans have very well understood it so far. Not so for black holes.
AFAIK, We defined them even before finding one IRL
I was reading through the history of black holes and from what I got from it, at first it was theorized that there can be dark stars, as I said in other comments. So dense that light can't escape them.
Ofc, I get your point. I'm not saying that its "the truth", we can only speculate. I just meant that that's how I see black holes, and it makes the entire thing quite interesting for me ;)
A big factor for confusion here is that I'm not really sure how much of the stuff I've heard about black holes are just a theory vs how much is actually evidence based. Everytime I hear about black holes, I hear all of these same things, singularity, event horizon, etc.
One thing we both agree here is that our knowledge about the universe is limited. I'm not saying your theory can't be true, I'm just trying to explain why I find it confusing. Ofc, we have different POV about black holes 🙂
Yeah, I was just trying to say how I can't call something so tiny like singularity a ball. Ofc, it'd be different if your theory is right and is actually a star/planet, then we can call it a ball. This is why I said we have different POV when we think about a black hole, the singularity comes to my mind but maybe a ball made of dark matter comes to your mind 🙂
> in most cases you see it as a sort of "gas" that still has a decent gravitational pull from my understanding, but at times under tremendous pressures it coalesces in the form of a star.
Ofc, this is a possibility, I understand that. But my point here is that it can't go from a planet to a gas, only the other way around. So if you're saying all dark matter are created when black holes are born, be it a black ball/star, it'll never become that foggy patches shown in the NASA Hubble map.
When a star becomes a neutron star it loses mass/energy in the process of collapsing, and those remains will transform into gas clouds of the normal matter that this star was made of. That's what my "brian" :) told me one night, maybe when a star becomes a dark star, it transforms matter into dark matter and it also shoots out this sort of dark matter when it collapses, like all stars do.
Also I find it bizarre that this super strange "point" (singularity) has a magnetic field like all stars have. As far as I understand it. It makes more sense for it to have a magnetic filed if it is a dark ball in my mind at least.
If your theory proved to be right, they'll probably change the name from black holes to something like black balls (which you suggested) since it wouldn't fit the definition of a black hole. So instead of saying there's a black hole at the centre of every galaxy, they'll be saying there's a black ball there 😉
Thanks, I'll take a loot at that. I like learning about quantum mechanics, its probably the most insane/craziest fields of science ever. It feels literally like magic to me, and I can't believe these things are REAL, I mean WTF ?
BTW, you can try doing the double slit experiment at home - youtube.com/watch?v=kKdaRJ3vAm… I'll do this one day when I buy a laser, a cheap one should be enough I think.
> When a star becomes a neutron star it loses mass/energy in the process of collapsing, and those remains will transform into gas clouds of the normal matter that this star was made of.
Ok, this is actually what I wanted to hear, now your theory is making more sense to me, and I understand it better now 😀
I just couldn't think of any way its mass could spread out, haha 😂 So the answer is a supernova explosion that spreads out the mass of these black balls that are made of dark matter.
I was suggesting that maybe they are entirely made out of Dark Matter. There is no "event horizon". How can this "solve" anything? Well in my mind they bring "home" these theories and are dealing with particles rather than unexplained forces and the ripping of space and the "disappearing" of matter and even light. If my theory would be true, and ofc probably is not, but if it was then is simply about different states of matter.
Just to be clear, is it OK if I keep the discussion classical (as in, no quantum mechanics), or does your claim refer to any quantum effect?
When you say that "there is no event horizon", do you mean that ... ?
We need an alternative relativistic theory of gravitation (ie an alternative to General Relativity (GR)), where there is no solution with event horizons
BH are formal solutions to gravity equations, but the black things we see in the sky are actually DM stars rather than BH
I am afraid that my brain is too busy with "making money" these months so I can't be that engaged in such discussions....which is very sad to me but that's what this society makes out of us....we have to trade, else we can't make it.
As for your points I'd simply say what I said in the article. Gravity, from my understanding, is not very well understood nowadays. Maybe black matter is so heavy that's why it attracts matter into it and we think that's a black hole.
I see, I wish you all the strength you need to overcome this. I have nothing against "necrobumping", so feel free to resurrect this conversation whenever you have the time for it !
They even have one where you can imagine you are diving into a blackhole and what you perhaps can see (except being ripped apart immediately or "spaghettified" as serious scietists call it :D), again, according to the latest scientific theories and models are known to date (mind blowing!!!): youtube.com/watch?v=4rTv9wvvat… Here you can do that youselves in 360: youtube.com/watch?v=17tEg_uTF_…
All in all, I recommenend that entire channel to watch, so you can take a grasp of very complex notions like space mechanics or quantum mechanics in a very digestable way: youtube.com/c/ScienceClicEN/vi…
@tio Yeah, sure. Nice one, btw :) Maybe it will help to bring more details to your theory ;) Damn, I wish more convos like that in modern society. Like people theorizing stuff here and there about Universe, about their home. How much of a progress could we achieve with not only scientists thinking of it, but many more people involved..
I can imagine, man.. :( So called "civilized" society can't offer us more than trading ourselves to make a living and to help others to trade their shits by engaging into buying more and more stuff..
A new TROMjaro ISO is out and we have a FORUM! forum.tromjaro.com/ :) - finally! It is much easier to manage that for releases, bugs, and announcements. So from now one that's the place to visit if you want to report bugs, see about the new releases, or some tips we will provide. Changed a bit a few pages on tromjaro.com/ to reflect these changes. You can still follow these all via RSS tromjaro.com/follow/ but no more email updates for releases. #tromlive
