PeterDonis reacted to PAllen's post in the thread I Synchronizing clocks in an inertial frame if light is anisotropic with
Like.
KE is dependent on relative velocity between detecter and particle. However, it not dependent on synchronization convention. It is, in... -
PeterDonis replied to the thread I An invariant while crossing the horizon.What thread? Please give a link. Yes, that's fine, although the specific value of ##\tau_1## has no meaning off of that observer's...

PeterDonis reacted to javisot's post in the thread I I don't see how a black hole's event horizon can be crossed with Like.
Looking at the entire conversation, it's as simple as correcting you and explaining the standard solution. Personally, I usually use...

PeterDonis reacted to Nugatory's post in the thread I I don't see how a black hole's event horizon can be crossed with Like.
This is a false dichotomy. For purposes of constructive discussion of special relativity, forty or so hours with Taylor and Wheeler’s...

PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.The issue is not how to tell an assertion from a question. The issue is what questions you are asking and whether they are answerable...

PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.If you're asking why relativity of simultaneity is not involved with what we're discussing in this thread, it's because whether or not...

PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.I think you're misunderstanding my point. We all realize that you didn't understand when you made your OP to this thread that you were...

PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.You missed the part where @Dale said not to propose a resolution of your own. Pretty much all of your OP, as quoted below, was proposing...

PeterDonis replied to the thread I Question about discussions around quantum interpretations.Yes, but you aren't giving any references at all to any literature where this "perspective" is discussed. As I said, even in this...

PeterDonis reacted to Herman Trivilino's post in the thread I I don't see how a black hole's event horizon can be crossed with Like.
It was actually Wolfgang Pauli who is famously credited for saying "that is not even wrong". It's not clear if he said it as a reaction...

PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.That's good. Note that the paper answers your original question: see the answer to the first bullet at the top left of p. 2. (The reason...

PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.In fairness, those are not a tool that would normally occur to someone not familiar with the subject. But they are a very useful tool, yes.
-
PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.No, that's not the two spacetimes. Both of the things you describe are true in the same spacetime--the "eternal" black hole spacetime...

PeterDonis reacted to Ibix's post in the thread I I don't see how a black hole's event horizon can be crossed with Like.
The question you need to answer is what you want out of the discussion. If you want facts about black holes then almost any source is...

PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.No, nobody has said that. What we have said is that what questions you can usefully ask will depend on what background you have, so you...
