Question

Is the MWI symmetric in time?

Answer 1

$\underline{\underline{\Huge\mathfrak{Answer ;}}}$

Yaa MWI is perfectly in time-symmetric.

• As every other formalism of quantum mechanics.

• The irreversibility is a second-law-type thing; it's very unlikely for two distinct 'worlds' to recohere for the same reason you won't see an egg uncook itself.

Answer 2

$\textbf{\huge{ANSWER}}$

Ya ! absolutely MWI is in time-symmetric because as all other formalism of quantum mechanics and the irreversibility is a second-law-type thing; it's very unlikely for two distinct 'worlds' to recohere for the same reason you won't see an egg uncook itself.
