comment Is the momentum operator diagonal in position representation?
I was looking for some more explanation. I mean, I already "knew" the answers to my questions. What I needed was to know why, or get some intuition.

comment Why $\displaystyle i\hbar\frac{\partial}{\partial t}$ can not be considered as the Hamiltonian operator?
@Revo You should check out Sakurai's book on quantum mechanics.

@josephf.johnson It makes sense to write $[\hat{H},t] = 0$, just as it makes sense to write $[\hat{H},3.14] = 0$, because $t$ is just a number.

comment Why planets are rotating only in one plane?
Also: Why are our planets in the solar system all on the same disc/plane/layer?

In one line: Conservation of angular momentum. See: Questions about the Solar System

comment What properties are entangled in quantum entanglement?
Not only you can entangle any property of the two particles, you can also, in principle, entangle one property of one particle (say its spin), with a different property of the second particle (say its position).
