Multiverses are a lame attempt to get around the staggering odds against evoloserism and evolosers. Relativity is a bunch of bullshit just like evolution. There is only the one universe which we live in, there aren't any others. There is only one time, there is no such thing as "space-time".

The whole facade of 20'th century bullshit magic physics is collapsing and will be gone in another 30 years.
