Like.
Because you're starting from premises that have nothing to do with the black hole scenario. You need to start fresh, from premises that... -
Foretranimal reacted to PeroK's post in the thread I I don't see how a black hole's event horizon can be crossed with Like.
When I was learning relativity I realised that all this about "perspectives" and "observers disagreeing" was unnecessary and leading the...

This thread has moved quite fast and I've not fully caught up, so apologies if this repeats things already said. There are different...

Foretranimal replied to the thread I I don't see how a black hole's event horizon can be crossed.When I say disagree, I am only referring to observations made in different referance frames. I do not see a paradox in the differeing...

Foretranimal replied to the thread I I don't see how a black hole's event horizon can be crossed.Awesome - thank you. Please tell me how my premises are flawed, so I might learn. OK, I believe you. What are my specific background...

Foretranimal replied to the thread I I don't see how a black hole's event horizon can be crossed.I respectfully disagree: There is intrinsic value in looking at a flawed analogy for the purpose of figuring out why the analogy is...

Foretranimal replied to the thread I I don't see how a black hole's event horizon can be crossed.Heh... I may have made conflicting claims. But honestly, I did not mean to make a claim. My understanding of spacetime and blackholes...

Valid is a fine word. If you want to go beyond valid then a more clear description is that the principle of general covariance says that...

If you mean that relativity of simultaneity is involved in the "barn and ladder" scenario, yes, that's true. But relativity of...

"Now" is not a physical thing in relativity. It's a convention. Trying to think in terms of "now" will only get you very confused...

That's true, and that's why I said that an evaporating black hole, which only lasts for a very, very, very, very, very long time, is...

No. The five infinities I mentioned in the article aren't important for what we're discussing here. They're a more technical point that...

The equivalence principle says that sitting in a box at rest on the surface of a gravitating body (for example, in a closed room on the...
