pretty cool thanks

try brian greene's the elegant universe very informative

the first thing you should understand about quantum mechanics is that some of the main principles are the uncertainty principle which states that you can not calculate the exact velocity and position of a particle.this is because you need to use em that has a short wavelength to find out the position but the short waveleth EM has a higher frquency which means that the velocity of the particle willl be affected to much.and vice versa for short wavelength EM

because the highest mass is usually at the center cause the gravity is attracted to that point according to the laws of physics.from your first question a singularity is different to a black hole cause singularities can be in other forms such as the bis bang or the predicted big crunch so its not only in a black hole

I agree with paranoia cause anti matter does behave like matter but the thing is that when matter and antimmatter meet they annihalate each other to pure energy but matter and energy are interchangeble.

the answer is yes but the olny way you can travel to the future is if you can make yourself age slower which means you will either have to travel close to the speed of light [that is if you want some results toprove you can] or go into a safe orbit of a massive object that bends spacetime a lot, like a black hole which would really give you some results but the main fact is that this is currently out of our technological reach so i dont think you will be able time travel or have time travel possible in your lifetime.
