PeterDonis replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.Then it can't possibly support the two wrong claims you're making. I never said @ergospherical's calculation was wrong. I only said it... -
PeterDonis replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.@ergospherical is not making the two wrong claims you are making. He's not claiming that the Levi-Civita connection has zero curvature...

PeterDonis replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.Not if your reasoning doesn't make sense to me. Your answer is obviously wrong because your answer is that the Levi-Civita connection...

PeterDonis replied to the thread I Hawking After 54 Years Confirmed: BH surfaces don't shrink.Note that this law only holds if energy conditions on the matter are satisfied. In the case of black hole mergers being observed by...

PeterDonis replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.You were given a link to a Wikipedia article that shows this way back in post #2 of this thread.

PeterDonis replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.They're not equal in any spacetime other than the flat Minkowski metric, since the whole point of the teleparallel connection is to put...

PeterDonis replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.No, it isn't. They're two different things. No, it isn't. The Levi-Civita connection has nonzero curvature in any metric that's not the...

PeterDonis replied to the thread I Follow-up Einstein Definition of Simultaneity for Langevin Observers.No. "The same Langevin worldline" means a worldline that's one of those at the radius you're working with.

PeterDonis replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.Which "metric compatible equation:"? There isn't just one. There are as many different metric compatible equations as there are...

PeterDonis replied to the thread I Does a qubit break interference in the double slit experiment?.Only if the result of measuring the particle is only consistent with one given result for the qubit. Whether that's the case will depend...

PeterDonis replied to the thread I Does a qubit break interference in the double slit experiment?.There are already plenty of calculations in the literature showing how which-way information can destroy interference. There are also...

PeterDonis replied to the thread I Does a qubit break interference in the double slit experiment?.Not as stated, no. If all you have is the qubit, you've just entangled the qubit with the particle going through the slits. Decoherence...

PeterDonis replied to the thread I Does a qubit break interference in the double slit experiment?.That isn't a quote from @pines-demon. It's @pines-demon quoting from the transcript of the podcast he linked to.

A vector ## \ket{\Psi} ## in Hilbert space, multiplied by any complex number(*), represents exactly the same state. That's why it is...

PeterDonis replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.No, because "compatible" isn't just one thing. "Compatible" if the connection is the Levi-Civita connection gives you one equation that...
