Like.
Hi, I'm curious about the following: taking the point of view of the standard physics of spacetime including EFE's solutions, are there... -
Jjavisot replied to the thread Undergrad Do existing EFE solutions support Closed Timelike Curves?.There are many EFE solutions that violate some, several, or all of the energy conditions. In addition to Gödel's universe, the interior...

Yes, of course. For example the Gödel spacetime.

Jjavisot reacted to PeroK's post in the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics with Like.
Imagine that we were living in a simulation. Everything would look the same, but there would be no force of gravity, as such. A...

In fact, Rovelli developed the relational interpretation inspired by his work in loop quantum gravity. He discusses this in section 4(c)...

Note that the Rovelli paper above does not consider the question of the existence of an electron, as we have been discussing it here...

Hi @PeroK! Your objections relate to certain metaphysical assumptions that you take for granted, but which RQM rejects. First, I would...

The fundamental principles of QFT, however, include many measurement operators that can be constructed by smearing the measurement...

Jjavisot replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.In QM, "particle" means "quantum object." By quantum object, we mean an object for which the uncertainty principle, superposition, etc...

Jjavisot reacted to Hornbein's post in the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics with Like.
I often read that an experiment is testing relativity or quantum mechanics. I think the experiment is really testing some new machine...

You can't throw an electric field at your head either, yet, according to Wigner's no-interaction theorem, it must actually exist...

Put in an extreme instrumental form, I think "The ultimate test for a model is the agreement of its predictions with experiments"...
-
Jjavisot replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.I see the same problems as you; the reasonable thing to do is assume they exist without needing to measure (the electron exists between...

How can you measure something that doesn't exist? Would two non-existent electrons be different from one non-existent electron? If...

Jjavisot replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.-The value of a measurement exists without needing to measure it. -The value of a measurement does not exist until we measure it...
