Modern theories of cosmology appear to predict that our region of space is a minuscule fragment of a huge ‘multiverse’, where over vast distances physical properties, and perhaps the nature of physical laws themselves, can change.
This talk explains what has drawn cosmologists to this viewpoint and indicates that there is some observational evidence supporting it. The talk also covers some rather unnerving implications of these ideas, including the possibility that the multiverse contains many, maybe even infinitely many, perfect copies of ourselves.
