Hi
I like the discussion here, however, I am a bit short of time so I will
pick out 2 points only.
No 2 objects can occupy the same space simultaneously but 1 object can occupy 2 different locations at the same period in time (or appear to.)
That's a strange remark. What's an object? Myself, I am an object, and
at the same time, a part of myself is at the floor while another is up in the air

That's a simple pictures, but actually shows some thruth:
Define object. Then, define how you describe the object: Are you using
wave-function for the quantum object? Are you using a quantum field? Note
that Quantum Field Theory is more fundamental since Quantum Theory, since
the quanta emerge from the field.
In this qm-sense the object actually is everywhere (based on the Kopenhagener
interpretation of the wave function \psi: propabililty |\psi|^2), however,
when you measure it, it is somewhere with a particular uncertainty (Heisenberg).
Since you don't know where it is (exactly), how can you say it is at several
positions at the same time?
Even more - it is still not clear whether electrons are point-like. It is still not
clear how quarks and gluons actually "look" like - the more energy you pull to
be able to resolve space more clearly, the more you see that quarks and
gluons consist of quarks and gluons...
I've never really understood the explanations as to why entanglement isn't evidence of information moving faster than light. If that is so isn't it also so that an electron particle is occupying 2 locations simultaneously?
In simple words: because you don't know of entanglement until you compare
results. You only can compare results without violating causality. I have written
something more here[1]. As a consequence of the famous experiment,
quantum cryptology[2] gets its foundation - and _not_ violation of causality.
Cheers
