Fun idea, but &quot;according to scientists&quot; and &quot;according to prevailing quantum theory&quot; are questionable. The many worlds interpretation isn&#x27;t as mainstream as this implies (and many non-physicists think).<p>Personally I don&#x27;t think it makes any sense at all, although I have a mere batchelor&#x27;s degree in physics so I&#x27;m not particularly well qualified to judge. I&#x27;ve never had a satisfactory answer to the simple emperor&#x27;s new clothes question, which requires no knowledge of QM to ask, &quot;If every outcome happens, in what sense is one outcome more probable than another?&quot;<p>Because it is (experimentally, based on repeat trials), and QM furnishes us with the probabilities.<p>This is sometimes stated as &quot;How do you get the Born rule?&quot; but it&#x27;s a simple and obvious question as soon as any sort of multiverse is proposed. I&#x27;m aware of the attempts to answer the question using decision theory but while they produce the right numbers they fail to provide a convincing justification for or interpretation of them (vs the simple, experimentally falsifiable frequentist view &quot;if you repeat the experiment you&#x27;ll see the frequencies approach these probabilities&quot;).
