Matterwave's latest activity

Very noob question, and totally understand if the answer is "go read the paper", but to what level of detail has this "interpretation"...

Local energy momentum conservation also happens in Newtonian physics (and indeed there, global energy momentum is well defined and...

Information that would allow clock synchronisation. Thanks Bill

Could you elaborate the point? For example, when I read "the fundamental relativistic rule"... And then the definition you gave, am I to...

Genuine question since I'm no expert. Is this true of all string theories? Or does one use this limit to reduce the space of possible...

"Hard" professors can be excellent. "Easy" professors can be horrible. I would think the goal is to avoid bad professors in favor of...

What are these "things"? The quantum states in QFT are of the field. So, I don't understand what is meant by quantum states generated...

In the US I think you can at least try to figure out *when* to take a certain course and *which* elective courses to take. There's...

AI is certainly over hyped, but even if it is significantly over hyped it can still be totally transformative for society. The hype is...

For me, even just the "standard QM" way of expressing an entangled state as explicitly one that is not a simple tensor product state...

No, that's not what he said. He said they are a two-particle excitation of a quantum field. That's not the same as a one-particle...

Ah, found the statement from Wald that I was trying to look up. I should have just quoted him instead. He is far more rigorous than me...

Fair, if the consensus is to treat ##\nabla_a T^{ab}## as a general statement of conservation of energy in GR then that's fine with me~...

Maybe to the OP I can make the following (I believe) fully non-controversial statement: GR "obeys relativity" and yet admits solutions...

No "energy" in the sense of Noether's Theorem; but local conservation of stress-energy still holds, since the EFE always holds in GR. So...
