comment What makes the stars that are farther from the nucleus of the galaxy go faster than those in the middle?
-1. I don't think this place is for original research. If you have a fantastic new solution to the dark matter “problem”, the best way of proceeding would be to publish it and have it accepted by (at least some) other professional astrophysicists. Then (but only then), referring to it in a physics.sx answer is a good idea.

comment What does it mean that quantum teleportation can be classically simulated?
Not that the teleportation is simply the identity operation (same input as output), so it is no surprise it can be simulated on a classical computer...

comment How do you find the time dependent equation of motion here?
Your exercise is a homework exercise, and we do not have enough context to know what you are asking. Surprising, the full treatment of the pendulum motion for arbitrary positions is quite complex, involving elliptic integrals (see e.g. Wikipedia if you want more details) and beyond college level. You probably want to assume some approximation (small angles) to have a reasonable solution.
