Half the time matter does not exist.
Interesting as is most theoretical physics when considered by laymen. However theoretical physicists are not much different than philosophers. The question is are these theories proven by reproducible definitive experimentation. Not saying the “big bang “ theory is wrong but how would you prove it and how do you explain all the matter of the universe originating from such a small theoretical volume? Or please explain how 0x0= anything other than 0.
