Jjavisot replied to the thread High School Why light can travel at c?.We can study the propagation of light in a vacuum without considering the source that originated it.

Jjavisot replied to the thread High School Why light can travel at c?.What source exists for light in a vacuum?

Like.
That the speed of light is invariant is a postulate of the theory of special relativity. As such, it needs no deeper explanation beyond... -

Re: the title ##c## is defined as the speed of light in vacuum. Define "break relativity". Tachyons would have very weird properties...

Jjavisot replied to the thread Undergrad Gerard 't Hooft on the incompleteness of quantum mechanics.The title was "shut up and calculate", a title that had nothing to do with the development of the thread.

Jjavisot reacted to PeterDonis's post in the thread Undergrad Could a black-hole interior contain an entire universe? with Like.
No. Not at all. A black hole spacetime has only three parameters, mass, charge, and angular momentum, and those are the same inside and...

Jjavisot reacted to PeroK's post in the thread Undergrad Gerard 't Hooft on the incompleteness of quantum mechanics with Like.
Here's an analogy. Determinism would say that the outcome of every soccer match is predetermined. Or, at least, that the outcome...

Jjavisot reacted to PeterDonis's post in the thread Undergrad Gerard 't Hooft on the incompleteness of quantum mechanics with Like.
His model is certainly different from BM, and he appears to be relying on superdeterminism to reproduce the predictions of standard QM...

Jjavisot reacted to Demystifier's post in the thread Undergrad Gerard 't Hooft on the incompleteness of quantum mechanics with Like.
Yes, at the practical level, that's correct. But at the conceptual level, the origin of UP is explained somewhat differently. In my...

Jjavisot replied to the thread Undergrad Gerard 't Hooft on the incompleteness of quantum mechanics.Do you think Gerard goes further than BM? I mean, BM respects the UP (he treats it differently, but he respects it). Gerard seems to...

...is not really about "randomness". It's about the consequences of having non-commuting observables. "Non-commuting" does not mean...

Jjavisot replied to the thread Undergrad Gerard 't Hooft on the incompleteness of quantum mechanics.Correct me if I'm wrong, Demystifier. In BM, evolution is deterministic: if we knew the wave function and the initial configuration of...

Jjavisot reacted to PeterDonis's post in the thread Undergrad Gerard 't Hooft on the incompleteness of quantum mechanics with Like.
No, they don't. I already explained how the two things are different in Bohmian mechanics, in posts #54 and #57. You even quoted where I...

Jjavisot replied to the thread Undergrad Gerard 't Hooft on the incompleteness of quantum mechanics.You seemed to agree with this statement. But you seem to disagree with this other one, and the curious thing is that both statements...

No, I mean that just quoting the opinions of someone, with no supporting argument, no data, no theoretical basis, just them making...
