PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.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... -
PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.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...

PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.True. But they can exist for a very, very, very, very, very long time. For example, the expected evaporation time by Hawking radiation...

PeterDonis replied to the thread I I don't see how a black hole's event horizon can be crossed.There is. First, read this Insights article: https://www.physicsforums.com/insights/black-holes-really-exist/

PeterDonis replied to the thread Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality.Reopening thread to reply. It means what relativity says it means. We're discussing physics here, not philosophy. Relativity of...

PeterDonis replied to the thread Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality.Thread closed for moderation.

PeterDonis replied to the thread Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality.It's a necessary implication of relativity. Relativity of simultaneity does not forbid the actual distribution of stress-energy in the...

PeterDonis replied to the thread Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality.The same "property" would apply to correlations between observations made at the same time at different places--for example, in any test...

PeterDonis replied to the thread Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality.This isn't saying that the past isn't real unless we have records of it. It's only saying that we can't evaluate predictions about...

PeterDonis replied to the thread Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality.Yes, it does, thanks!

PeterDonis replied to the thread Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality.Yes, I agree. But I still don't understand what you mean by what I quoted from you in post #14.

PeterDonis replied to the thread Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality.I'm not sure what you mean by this. In the MWI, "worlds" split when decoherence occurs, and decoherence is much broader than "records"...

PeterDonis replied to the thread Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality.Hm, that's odd, it's not showing up as a title tag option any more. @Greg Bernhardt is that something peculiar to the QM...

PeterDonis replied to the thread Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality.And I have now moved it there.

PeterDonis replied to the thread Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality.Ah, I see, by "quantum information theory" you meant your particular interpretation of where the standard QM predictions come from. In...
