    I never liked how these youtube videos depict masses having bent space only under them as if universe is flat, which really disappoints cuz its not if you cant animate gravity for a sphere that is actually spheroid and not like a ball on top of a cloth, i dont know who will, which makes your “educational content” invalid and turn it into just one of those view money grab videos. My disappointment is immeasurable and my day is ruined

    First of all, absolutely fantastic video as always, I'm addicted to kurzgesagt and love every single video!! However what I don't quite understand is how light can be bend/pulled by a black hole. I mean if I understand correctly, light is made out of fotons - bundels of electromagnetic energy without mass. So, (again If I'm not mistaken) gravity always works between two masses, so how can something without mass be pulled by gravity? If you look at the formula of gravitational force, you multiply both masses, so if one is zero the total would be zero as well regardless of how big the other mass is, right? Or does it have something to do with the concept of everything being relative? That being said, a thousand thanks for this brilliant and fascinating content 🙏🍀

    Would you be able to cross the event horizon though? Due to the extreme time dilation close to the event horizon plus Hawking radiation the black hole will probably evaporate just in front of you as you are falling into it whilst you are completely toasted by Hawking radiation which is now incredibly strong because of blueshift. From a distant observer's point of view this will take 10^100 years but for you it will be over quite quickly. There is no "inside" a black hole, space and time are pinched off.

    Black holes just sound like a defensive cloaking field used by waring aliens who don’t want to involve all the indigenous life on planet so they use basic physics problems like a black hole an object that really shouldn’t exist but the math kinda makes enough sense to confuse the smartest of the basic life forms. I jus think about when we fight other humans we rarely stop and think about the animals impact we have, only a few times we’ve taken that into account but I bet it’s just like the toy animal with a camera inside that fools the other monkeys into thinking it’s one of them.

    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.
