Some evidence of a multiverse.
It is a little sad the way good words get ruined sometimes. They start off with meaning X and then, for a few decades, they become closely identified with concept T. After awhile people realize that T is just a subset of what X used to mean, but by now the word that used to refer X now refers to T. So a new word needs to be invented to refer to what X always meant.
That is now happening with the word “universe”.
500 years ago the word “universe” referred to everything that existed.
For the last 80 or 90 years the word “universe” has referred strictly to the observable universe.
Now the word “multiverse” is starting to refer to what the word “universe” used to refer to.Source
