I did not miss anything. Multiverse can logically apply only to the term observable universe, NOT the totality of existence.This is a perfect definition of OUR universe. But you did not pay attention at the end when he touched on the subject of multiverse.
And said that is is the subject of another verse.
So you missed the meaning of another universe completely, and I find that awfully convenient on your behalf.
Henry Reich defined the terms in the video:
Universe (capital U) that encompasses absolutely everything that exists (even all possible universes of any number of your so called multiverses).
universe (not capitalized) that is observable to us.
Do you accept these terms as explained by Henry Reich? Yes or no?
