The universe is only half of the world: the so-called Big Bang has been shown by Hawking to originate from a "gravitational singularity", a "singularity" with infinite energy and infinitely small volume. Where does the "singularity" come from? If it can't be explained, isn't the "singularity" a god-like existence? A basic premise of causality is that everything has a cause, and the cause of a singularity can no longer have a cause. There is only one possibility, and that is that the cause of the singularity is "zero point", something like a vacuum. The premise of everything having a cause is existence, and why does the zero point not exist? Then there must be another "negative singularity", which is zero in sum of energy with the "singularity". Singularities produce the universe, based on positive energy, and negative singularities produce negative universes, based on negative energy, and the universe is only half of the world. Some people will ask that energy is scalar (no direction), how can there be positive and negative, then the charge is also scalar, why is there positive and negative?
