I believe in Universes beyond our own, groups of universes as we have galaxies of stars, and clusters of groups, and on....... unending. This gives me the vaguest perception of what and how big God is. God is very great. And so I am a Deist.
Several leading scientists argue for multiverse now, some because they have observed that certain of our clusters of galaxies are moving 'out of sync' with the rest of our universe, some believe in 'curtains' which produce universes wherever they touch. Some try to explain string theory and some just hold their hands apart and say, 'Of course'!
A lay-person, I have always had difficulty in believing that God is finite...... it just seemed to make 'lay' sense. And since this all makes me so tiny, so miniscule, so 'nothingness', I become calmed and feel that I can be content with the flow of time. I enjoy each moment. I feel very lucky.
Yes.......... Multiverse..... multiverses... groups of them...... groups of groups..... of course.......
