Quantum Physics is Time Travel Theoretically Feasible
By: Clayton A. D.
Arguments of quantum physics concerning the travel of time could never be resolved as those who say "Nay" will state various theories concerning infinite mass, lack of fuel, lack of the ability to stop, etc., while those who say "yea" will argue that we simply...
