About this episode
In previous episodes, we discussed the multiverse's sole "prediction" that we are typical
observers in a typical universe. However, this ignored the major problem that it doesn't seem
possible for an infinite varied multiverse to use probabilities to make any prediction whatsoever
because there are an infinite number of copies of every possible universe!
To get around this problem, multiverse scientists use something called measures to compute
probabilities in an infinite multiverse and then determine what a typical universe looks like. They
thereby attempt to rescue multiverse theory from the fatal flaws of a naive multiverse, but end
up running directly into the measure problem we'll discuss next time.
