    Hey kurzgesagt, can you soon make a video about brain/head transplantation? I looked it up and it is very interesting. And maybe you can give a proper answer if people can live forever with brain/head transplantation. I hope so, because I also think that in the future ( with more advanced technology ) we can use black holes to speed up ourself in space. If you make sure that you get into the spinning orbit around it, and also get out of it, than you will get out of it with much more speed. Maybe we also can get energy out of a black hole... That's why I hope that brain/head transplantation soon will make you live forever, because I want to witness it. Maybe these are some interesting thing, maybe not. We'll see. ( Sorry about the grammar, English is not my best language ).

    I watch every video I can find on Black Holes, but can't seem to find a detailed answer on this... Do we know for certain that Black Holes have a Singularity? In the sense that everything is at a single point with 0 Dimensions. It is possible that it is a physical sphere that exists in 3 Dimensions like a Neutron star but more densely packed (say a Quark star)? Mathematics and logic would suggest that it must have a true physical size and not a single point with no dimensions (division by zero is illogical to even state as an equation, it not only has no answer but has no reason to ever be asked). Say a Neutron star of 10KM that has an escape velocity of 50% the speed of light, what if it compacts to 5KM as a Quark Star (or some other sub-Neutron sized particle) with an escape velocity of equal / greater than the speed of light so we cannot see it and would "think" we are looking at a Black Hole but if we could it would still be a sphere, just more Dense (I know that math isn't perfect, just creating a concept)... why do we default to an idea that it has 0 physical size? Do we really know for sure this isn't the case? Maybe a different sub-atomic particle that we have or haven't yet discovered is the true "crunch limit" of matter and the stuff Black Holes are made of. I've heard before about Singularities that (they are not real, just a placeholder explanation for what we cannot yet explain like saying "Magic" in the middle ages for events that we could not explain via science at the time). If it truly is a point of 0 Dimensions than it would not matter at all how much mass the Black Hole is made of, all of them would have identical event horrizon radii. 20/0 vs 10/0 does not give two different answers, the fact that larger mass Black Holes have larger event horrizons I would think would confirm the physical size idea, did I explain this concept well?

    I just thought of something. What if when the first black hole dies, everything the singularity contains is spewed out at once, along with the hawking radiation's antimatter explosions. This could be a new big bang, and a kickstart of a new universe. I challenge any youtube astronomer geniuses to test my theory.

    question: although the dying sun that collapsed on itself to create the singularity at the heart of a blackhole was spinning at an insane rate, afterwards as a singularity it has no size or dimensions that we can measure. which in itself is not possible because even compressed beyond neutrons there is still size and area. but assuming the math of gravity is so intense it crushes the matter into non existence, I have a question. How does a nonexistent non area of space exert a spin?

    Hi. I recommend you watch the documentary "Processed People". I'm not a troll, just someone who wants to spread awareness. Why? Well, because: "A deadly global pandemic makes one thing abundantly clear: Your health needs to be a priority. Not just someday, but right now. Did you know... Obesity, heart disease, Alzheimer’s, type 2 diabetes, cancer, and other chronic illnesses are all fueled by diet and lifestyle choices - and they make infections more dangerous." This was a quote from the "Food Revolution Summit Website", which you can visit. Please just consider it, it won't cost you anymore than a little bit of time, and you could actually benefit from it. Thanks.

    I'm assuming we use infinity to describe the density of a black hole because we aren't currently able to measure how crushed particles can really get. If we really knew what the smallest particles were, we'd probably be able to measure approximately how dense a black hole is. Right as a sun turns into a black hole if you could measure the size of the singularity you'd be able to determine it's real density based on the size and density of the star it used to be. To say it's infinitely dense is to say it doesn't have size, but rather it exists in a state of shrinking infinitely. Matter cannot be infinitely dense, as density is the measurement of how tight particles are, eventually they'd stop somewhere or else particles inside black holes would be crushing into smaller and smaller particles infinitely at infinite speed, to say they are infinitely dense is to say that particles can become infinitely small, none of this sets right with mathematics. TL;DR I theorize that there 'is' a limit to the density of black holes, we just don't know what that is because it defies our current measurement capabilities.

    I don't think anything goes to a single infinitely small point in a black hole. I suspect anything that falls in sticks on the surface (event horizon). I suspect this due to time dilation. You will never get to this center, you will fall for eternity, and experience the life of the universe in an instant.
