    I'm super confused and don't really know where to ask, so I'll try here. Why do people talk more about the center of black holes being a singularity which we almost know can't be possible, instead of being some sort of "quark star" ? Would quark stars of sufficient density not fit inside the event horizon, or something else really obvious? Idk, I just thought for the first time "what if it's just a bigger neutron star under the event horizon? could we even know?" , and that lead me to some weird stuff about quark stars and degeneracy pressure that I don't understand, and it's kinda weird that I haven't seen a video about it so it must be a really obvious error I'm making.

      I'm pretty sure they just evaporate away super quickly due to Hawking radiation. The effect scales with the inverse of size, so really big black holes evaporate really slowly, but really tiny ones go away really fast. I'm not an expert so don't take it as gospel, but that's what I always hear. Fun fact, I remember when I was like 6 I must've heard something on the news about CERN possibly making tiny black holes, and I broke down into tears thinking that the world was gonna end because I knew just enough about black holes to be terrified. If only my parents knew enough about physics to console me haha

      If you mean no one's gone to a black hole to test it, yeah you're right. But by that reasoning, there's no proof that rocks fall down on Europa. No one's thrown one while on it. Given that, maybe that's not the best way to look at the universe. We know how time and space must behave near black holes because the same theory that describes those effects which we can't measure directly right now, also describes lots we can. I don't know much about it, but if you look for information on "relativistic effects" , you'll find plenty

    I think our universe is what consists inside of a black hole. My theory is that the Big Bang and the description of how a black hole forms sound almost exactly identical, an unfathomable amount of energy crushed and focused down to a single point, then a sudden burst and rapid expansion. I think these 2 events are the exact same events, and this also points twards the multi-verse theory also being true(maybe,lol), since there are countless black holes of every size all over the observable universe, all containing they're own universe's of varying sizes, which in turn contain countless black holes, Exc... But PLEASE, somebody give me feedback on this, I've been trying really hard to get somebody with any scientific understanding to give me they're take on this theory, so I would really appreciate it.

    The big bang theory is just a guess so it likely is wrong. The universe probably began with a blackhole about twenty times bigger than the Milkyway galaxy it reaches absolute mass and explodes bursting out incredible amounts of matter the universe stretches and stretches for googol years and then black holes engulf all the matter in the universe and then they destroy each other and than overtime all the matter in the universe becomes one giant black hole and the cycle restarts after a very long time of compression. Still doesn't answer the question of how the first cycle ever started without there being anything before that.

    Ok so... ▶️ If when you are in a black hole, time speeds up, then won’t the black hole itself evaporate? ▶️ If there were 2 objects connected via unbreakable rope, when 1 part is inside black hole and the other is outside, if ‘any way you go goes towards the center’, then the rope must be in a direction, but it can’t go towards the center as it is is connected to the other one. How? ▶️ The rope wouldn’t be pulled if it went down, because the rope is the black hole’s radius. But it’s radius isn’t the radius, because with infinite density, it warps space infinitely, so the rope would be going in both no direction, infinitely long towards the center, then a direction in which who knows what happens. ▶️ If it bends infinitely, you have traversed infinite distance (in bent space-time) in a finite time. Wait no the time is infinite but dilated. So the rate at which you go (as in bent space-time) per hour is infinity divided by infinity. Great. (I’m 10 bruh)

    It wouldn't make sense that density of a black hole is infinite because they can grow. The more information/matter they consume the bigger they are, meaning the density inside isn't infinite. It can mean that the density levels inside of a blackhole are the greatest level of density of a information in the universe and that black holes don't have a core as they themselves have equaly everywhere the same density

      ​@Mihajlo Sreckovic It happened to me a few months ago, althrough I comment on YT very rarely, that my comment vanished a moment after I replied. It is probably due to yt algorithm that tries to keep the comments civil but sometimes malfunctions (and my comment then wasn't smth impolite or vulgar). Well it is a mistery then what is inside of a black hole. But dividing by zero by using a typical formula using general relavity sounds a bit inconsistent. Maybe it is the gap within our own constructed mathematics the reason why we just can't calculate more exact insides of a Black Hole. Then "Singularity" is just a fancy name for sweeping off the table the problematic of our own limitations when it comes down to predicting what is inside by using our current means as we cannot explain it right now with more confidence. Insides of a Black Hole are so extreme, the space-time continuum is so warped, that the laws of general relativity could just not work inside. Maybe when we'll understand more properly another aspects of the universe like dark energy particles and dark matter particles etc. then that would hypothetically allow us to give a better estimate. If Black Hole's gravity eats everything then it should eat these too and they would then change the properties of how the black hole behaves? It is said that the time inside of the black hole flows much slower or even doesn't flow at all. It sounds to me that black holes have two purposes :D First being the gravitational centre of galaxies and then second being "refrigerators" for information about matter. And then (this is just absolute guess, well this all is) when the "dark energy" runs out and universe starts contracting in space (the big crunch), in the timeline of the universe when nothing else than black holes remains, this information will be used for another Big Bang nucleosynthesis. Maybe Black Holes have some or all responsibility for the dark energy running out and then for contracting the space around them itself. And once all black holes collide into one another the next big bang begins sparking the next universe. This all comes with the assumption that universe is indeed finite.

      @Stanislav Kinzl I replied 10 hours ago, have no idea where my reply went xD. How do we know for sure? Well, we don't. That's why it's called singularity, we have no idea what it actually is. When you put the mass of a singularity and radius of a black hole in equations of general relativity, you literally start dividing by zero, and get infinities. It says that all matter should get to a point of infinite density, which is so absurd that we choose to call it singularity. This is so bad that we actually know that general relativity is fundamentally wrong. I mean, it's a great theory and makes very good predictions (like black holes), but it doesn't have to be the true nature of the universe. The problem with singularity is that, it has so much mass that you have to account for general relativity, but so small that you have to account for quantum mechanics, aka we need theory of quantum gravity, a theory that no one was able to develop. Thinking of singularity as point in space with infinite density is currently the best way we can think about it, but is probably fundamentally wrong.

      @Mihajlo Sreckovic So the gravity is so strong that photons cannot escape at some threshold, but it doesn't mean that that's where the matter of black hole begins. The matter continues being pulled by gravity to the centre of the spheric shape which is the singularity. But how do we know for sure? If the photons don't escape beyond the event horizon then there can be a matter amassed of any diameter (not in a singularity)

      @Stanislav Kinzl Black holes DO grow, but storage space is not increasing. Everything that gets into black hole becomes part of singularity, and singularity never changes it's volume, aka it's "storage space". The reason black holes grow is not because storage space is growing, but because gravity gets stronger (because mass is increasing), and thus light from farther away can't escape from black hole, which means it's event horizon has grown. So event horizon grows, but storage space doesn't change.

      @Mihajlo Sreckovic Right, but if density inside of a black hole was infinite, wouldn't black holes be just one point never growing and expanding but with variable mass inside being added to that one point with an infinite limit to its density? That's how I imagine infinite density - you can store all the mass in one place without ever needing to increase the "storage space" of it. If they grow it means that the insane gravity inside cannot dense everything in one point no?

    my brain understood that.... wow edit:- cuz like I understood how future time travel works in a previous video but past time travel got my brain a little but I understood why its locked in a blackhole cuz theories and gravity which is also the thing causing that theory/ reading to break universe is the only thing keeping it away if its possible and the way the light of the universe disappears makes sense aswell because a simulation of a blackhole is just like that since light is weird around it so the same applies when it s taking u away from the universe's light which is weird but makes sense cuz light is getting absorbed with you. I like science but I feel like its too much even if you go for specific things cuz this just scratches the surface of black hole weirdness
