Any comments on Believing in alternate universes?

Answer 1

Why not?

Answer 2

In physics?
A number of physicists, not otherwise known to be mad, have entertained the idea as it is consistent with mathematical models which otherwise do a very good job of accounting for the nature of the universe and in particular some non-instinctive effects found at the quantum level.

Until recently the other option which also covered the phenomena was "the Copenhagen interpretation" with its own associated non-intuitive ideas. (And Schrodinger's cat)

Whether new findings and discussion on quantum entaglement wil ease the situation, or prove the universe is still weirder than was thought, remains to be seen.

One thing seems clear. These "other universes" are not for travelling to. SF writers please note. they go off perpendicular, not parallel, to the particular one that I experience, (whatever "I" is).

But, (academically) consider quantum suicide.

Answer 3

There is no evidence for it, so its not something I would do.

And some of the theories say there never could be evidence for it, which means it is not science.
