I much prefer this explanation.

There is much resistance in mainstream science to a Multiverse.
The Multiverse is beyond our Universe's particle horizon hence there is no way we can test for its existence. This puts it beyond the realm of Science into Philosophy.

Thanks Steven,

Prompted by the Catalyst program and this discussion, I have my battered copy of Stephen Hawking's, A BRIEF HISTORY OF TIME next to me. Time to read it from cover to cover....again.

Stu.
