PeterDonis replied to the thread I Where did the early photons go?.Thread closed for moderation. -
As @PeroK is aware, the less than 2c limit is for a material object in flat spacetime. Separation velocities (the rate at which...

PeterDonis replied to the thread I Question about discussions around quantum interpretations.In physics is that you are using a model that predicts a random distribution of outcomes. If your model predicts the same outcome every...

PeterDonis replied to the thread I Where did the early photons go?.You're welcome! :smile:
-
PeterDonis replied to the thread I Where did the early photons go?.Briefly: An invariant is a quantity that is independent of any choice of coordinates. A scalar is an invariant that is simply a...

PeterDonis replied to the thread I Question about discussions around quantum interpretations.The definition of "chance" prevents it. That isn't something specific to QM.

Like.
Yes, there is a last instant of your home world's future that you will ever see. However, this last instant is not seen when you reach... -
PeterDonis replied to the thread I Where did the early photons go?.Because we have other ways of inferring what the properties of the universe were before it became transparent to radiation. For example...

If you want to go beyond popular science, then you could try An Introduction to Modern Cosmology by Andrew Liddle. This is at an...

PeterDonis replied to the thread I Question about discussions around quantum interpretations.QM doesn't say there is an "interaction" between the two entangled particles. Certain QM interpretations do, but not all of them.
-
PeterDonis replied to the thread I Question about discussions around quantum interpretations."Pure chance" wouldn't make it happen every single time. No, because "chance" would mean you would get different results on different...
-
PeterDonis replied to the thread I Question about discussions around quantum interpretations.That isn't the way cluster decomposition is presented in the literature, though. There's no claim that it breaks down for measurements...
-
PeterDonis replied to the thread I Question about discussions around quantum interpretations.This would need to be experimentally tested. They don't give any specific numbers, but there are experiments showing Bell inequality...
-
PeterDonis replied to the thread I Where did the early photons go?.That's an invariant which is due to the invariant expansion scalar, yes.
-
PeterDonis replied to the thread I Question about discussions around quantum interpretations.This paper basically seems to be saying that the correlations that break factorizability don't vanish when you look at the correct...
