@dannys.science: Black holes may not even have an event horizon.#dannyscience #STEMTok #fyp #blackhole #eventhorizon

Sic transit gloria mundi :

Nonsense, time slows down only for an outside observer, the person approaching the event horizon will not notice any difference

Emperor Sun :

If you can not enter the black hole, how it became the black hole? How does it grow?

Vebril :

Only people watching you from outside the black hole with see you get stuck. If you fall in you wouldn’t notice a difference in your own time. You’d be free to move just the same as if your floating in space you can move your arms and legs and head all freely. The only difference you’d notice is the stars and your ship behind you (if you looked back at it) would speed up. They’d get faster and faster until they became a blur and eventually all of the visible space would shrink down to a single point directly opposite from the singularity. You’d watch as billions of years would pass outside the black hole in just a single second. From the inside of a black hole it would be blindingly bright. Pure light because All the collective light emitted from every star and every planet over those billions of years would hit you all at once in that single second, making it extremely bright. And the deeper you went the brighter it would become. Essentially the inside of a black hole would be the theorized white hole. But none of that would restrict your movements. From your perspective your physical movements would go unchanged.

ragid :

The firewall theory is a thing. This explanation is not.

alrd128 :

The escape velocity makes perfect sense. I don't get it. Wtf is he talking about? if the escape velocity of the black hole is larger than the speed of light that explains everything. And no you cannot escape it because you cannot exceed the speed limit. So, again wtf is he talking about?

Dave :

No. This is not correct, and has nothing to do with the black hole firewall theory.

Greg Pugh845 :

Stay away from black holes 😳

DielliArt✨ :

Nonsense

Ale-Asca :

If this theory was right, 2 black holes could not merge, while we have observed that they can, and that they can grow up, that’s why there are massive black hole

brewp49 :

Ridiculous. If nothing can enter a black hole then they cannot grow. Which does not explain how they can become super massive!!!

Viking :

This is nonsense. You confuse proper time with coordinate time. According to GR, seen from the outside, Cooper will freeze, get more and more redshifted and finally disappear. From Coopers perspective he will enter the blackhole, depending of the blackholes mass, he will either feel nothing when crossing the event horizon or get spaghettified as he reaches the singularity. According to QM, Cooper will not reach the singularity but become encoded on the blackhole's surface as proposed by Hawking.

cragg2405🇨🇦 :

So the opportunity to reaccelerate to light speed allows you to escape? How? Nonsense! If the speed of light wasn’t enough before you were falling back, why is it enough now? Aside from getting spaghettified inside due to gravitational differences between head and foot, once inside the event horizon, you would accelerate to the singularity and parts might e centrally leak out through Hawking radiation.

Jesse S :

imagine having to spend trillions of years stuck in 1 spot on the edge of a black hole. you cant die. you have to just stay there in darkness, unable to move.

Larrene :

near to it... it needs to be near enough to it and or from it...

Lemon :

First off: That's not what black hole firewall "theory" is. Secondly: It's a hypothesis, not a theory. Thirdly: It's only widely discussed in the sense that it's the butt of every joke. Occam's razor and all that, there are far simpler and less convoluted hypothesis to explain the quantum entanglement paradox.

opɹɐɔᴉɹ | ricardo :

that's wrong. time flows faster as you get closer to the black hole.

Varulven :

the guy forgets light speed is not reachable if you have mass, therefore escaping a black hole is not possible, the definition works fine

Fluorine :

FireRestsByChanging :

E = mc^2 says that no mass can achieve the speed of light. Mass increases according to velocity. As an object approaches the speed of light, it approaches infinite mass.

Ofloo :

so you agree that gravity affects light then you also should agree that light isn't a constant.

Ninja :

then how does black hole get bigger if it doesn't swallow an object

patibo :

Cooper is frozen for an external observer. For him though he just keeps going at seemingly infinite speed.

Hawk GG :

Gasses and radiation escapes a black hole .. your argument is flawed

IoannisTsig :

We have no idea how the universe works, even light and gravity are still a mystery to us. We only observe not understand why and how . It is amusing that people here talk about black holes like we have some certain scientific knowledge about them
