Question: Are there other universes?

Paul Brack answered on 16 Jun 2015:

Some scientists think so, but we have no evidence yet. Some think that there are loads of parallel universes, where everything is the same except one little thing, like maybe you wore different shoes today. Some people think that there is an endless series of Big Bangs, giving birth to new universes all the time.
