Like.
No. Today’s quantum physics (quantum field theory) is fully compatible with relative time. Edit: @PeterDonis for the win! -

Not at all. Quantum field theory, to which ordinary non-relativistic QM is an approximation, takes relativity into account and is...

In the other thread yous said you were not interested in theories that will not be around in 100+ years. Well, this one has not been...

We don’t. All we observe is the dot on the photographic film screen where the photon landed and was absorbed. As an aside, any...

Then why would you make a claim that it isn't matter?

Nobody told me that in school. But yes, it's true that not everything you get told in school is correct. However, it's easy to check...

J. J. Thomson first showed this in experiments with cathode ray tubes in 1897. With the technology of the time, he was not able to get a...

You might be remembering a version of the experiment where you do try to detect which slit the electron went through so you have...

I don't know where you are getting any of this from. "Matter" is just a word; it can mean lots of different things. But its most common...

Many popsci presentations really grossly misrepresent “the” double slit experiment. There are at least three different types of “double...

More important than the past problems you've solved or the examples are the various types of logical fallacies, a couple of which you...

You seem to focus too much on what to do to get an A and not enough on learning. You seem to think that if you only memorized all the...

bhobba reacted to Matterwave's post in the thread Undergrad Spatial separation of entangled particles implies physical separability? with Like.
Not for the EPR state. It is still an entangled state and not a product state. When EPR says (something like) "after T, the two...
