Question about Quantum mechanics

[sol invictus]

I was saying instead of postulating so many different universes, maybe we should revise our concepts of space and time.

You don't "postulate" anything in the MWI except that the Schrodinger equation is the right equation to solve. Multiple "worlds" are an output of the theory, not an input.

As for "revising our concepts of space and time", one of the virtues of the MWI is that it allows one to think about a wavefunction for the universe.

Maybe instead of postulating a gazillion alternate universes, the correct path to solving these issues is to rethink our concepts of space and time?

The MW is an interpretation of QM, the behavior of very small energy packets is not classical or intuitive. The real solution is to aknowledge that they do not behave classically and are counter intuitive.

Now GUT will resolve the lack of coherence between the models of space/time and QM, both are very accurate in their domains.

GUT may or may not ever happen.

Yes, it does but not sure if I want to explain that here other than to say, obviously, MWI advocates alternative space (other universes).

My point is that the apparent violation of so-called physical laws is based on our idea of what is physical.

Um, you are imposing calssical concepts upon QM, does Feynman's sum over histories allow for time travel?

(Remember that the many worlds are not going to be 'have to be this, have to be that', they can be partial and limited in duration and spatial existence)

 

[Dancing David]

The same ones you mentioned.

Huh, what , where?

INSTEAD of postulating a gazillion alternate universes, maybe we should rather revise our concept of the universe (space and time).

Why? It makes absolutely no difference. The equations work out exactly the same no matter which interpretation you choose.

Randman and equations? I've never seen him use one.
