Essay Abstract

Assuming the validity of the Many Worlds Interpretation of quantum mechanics (MWI), we examine the possibility of changing the past by memory erasure. We find that while observers cannot change the probability of experiencing certain outcomes, they can nevertheless randomize past events and thus end up in a different sector of the multiverse. We also discuss Tegmark's quantum suicide thought experiment and show that, contrary to conventional wisdom, it {it cannot} be used by an observer to test the validity of the MWI for herself.

I failed to correct two typo's.

Eq. (7), the second term should be |No comet)

Eq. (10), there |O_initial) should be |O_notified)

I did spot these errors, but when I compiled the file for the last time, I forgot to run pdflatex :(

Dear Saibal Mitra,

Nice idea of the possibility of traveling between parallel worlds by applying the time reversal of the MWI branching – forgetting the past. Interesting analysis of this idea. Perhaps this can be related in a way to undoing quantum measurements.

Best regards,

Cristi Stoica
