What is a Black Hole? - Stephen Hawking's final theory

The way kurzgesagt described it was like a hologram of the previous thing, and its a good way to imagine it.


When you think about it, because gravity bends not just space, but also time, it makes sense that things wouldnt be completely destroyed, because it takes them an infinite amount of time to descend into the black hole, If you fell into it, you would never reach it, you would just be sitting there waiting, and waiting, and waiting, as you never got any closer, meanwhile the rest of the universe dies the heat death. The outside universe sees you ripped to shreds, and some weak or soft information preserved on the event horizon, but it takes an infinite amount of space time curvature to get black holes to work, and because the event horizon isnt actually the surface of the black hole, but just the boundary of no escape, all timelike paths become spacelike paths, and all spacelike paths become timelike paths, so youre inside there for several eternities before youre actually destroyed, leaving a quantum representation of yourself on the event horizon, and the rest of your mass contributing to the black hole itself.


Honestly, all this is fascinating, but i wanna know about mass fluctuations on a black hole, when it eats a star for instance, it cant possibly grow in radius equally everywhere all at once, because that would imply mass travelling faster than light, and nothing can do that, so it has to wobble, it must have surface waves, like water, expanding outwards in space.


The event horizon, the boundary of no return, might stay constant and expand as a ratio of its size/mass, but wouldnt it be cool, if you could spin up a black hole fast enough, and then hit it with a star, and cause its surface to wobble violently enough, that the event horizon ITSELF wobbles, contracting and expanding as its distance from the mass dictates, maybe even enough, that you could rescue something that was just inside the event horizon?


all im saying is, it would be cool to send a probe just inside the event horizon of a black hole, right as it was about to collide with a star, and see if you could get the probe back out, and what it would record while it was inside, if anything
