Theory of Conservation of Energy says ' Matter / Energy is constant and cannot be created or destroyed.' Then where did the energy of the Big Bang come from? Were the laws of physics violated at that time or is the Universe cyclic where after every cycle the Universe is reborn. What happens between the time the earlier universe is destroyed and a new universe is born. Is energy constant during that period? Or is new energy 'born' to replenish whatever 'losses' might have happened during the interim period??
