Physics, Astronomy & Cosmology / Re: Approaching An Event Horizon: Falling Observer vs Hovering Observer« on: Yesterday at 00:10:40 »
I didn't want to start another topic for it and appear to be spamming.The two-object argument also belongs in this thread. You don't need a separate thread for each contradiction you think you've found.
Gravitation is supposed to be time reversible, it's an attractive force either way. This doesn't hold once an object crosses an event horizon because then that object has to reemerge from inside the event horizon if the arrow of time is reversed and that shouldn't be possible either way.Not bad. Agree that this is even a worse offense than a black hold spontaneously forming from next to nothing as it un-Hawking radiates into existence. That's just an offense against entropy, but the emergence from beyond is outright time travel.
I thought Unruh radiation was a quantum mechanical effect, not a relativistic one. Could be wrong though.It seems to occur where the two models meet. Since we've no unified field theory, the exact description of such effects might have to wait. Still, an object falling to a black hole event horizon is destroyed and the one falling through the Rindler horizon notices nothing. The two seem not equivalent in that way, but equivalent enough to get the Unruh radiation.
Feel free to argue otherwise then, because I'm also in that camp. Yes, I think your examples (yes and no questions) suggest contradictions either way.Quote from: HalcHow wacky is your personal model? I think there are physicists on both side of the 'does it fall in' question, so both are mainstream enough. Not sure what you have in mind. You seem to be able to follow what I'm describing, so I'm interested.I was under the impression that the mainstream was well and truly in the yes they do reach the horizon camp. They definitely used to be not long ago but maybe that's changed.
My model is on the most recent page in the new theories section.The unified relativity thing? That's a lot more than just nothing-falls-in argument. Parts of that might well qualify as non-mainstream. I didn't particularly see this topic isolated in there.
