A vacuum that is not filled with all the energy and matter of the universe. When that happened it began to expand and cool and space and time were created. That happened 14 billion years ago. No one disputes it.And what is a false vacuum?A false vacuum.so, what, then. is a quantum universe comprised of?Matter and energy are space and time. One does not exist without the other.I said nothing about "space and time". I referred to matter, and energy.Except you believe that space and time had no beginning.
That just isn't the case. It began 14 billion years ago.
Nothing like the hot and dense state of our universe when space and time were created.
