Each Everettian world has an amplitude, which is a Complex Number not a Rational Number or even a Real number like a probability, associated with it. The square of the absolute value of that Complex Number can give you the probability that you are in that world, and Gleason's theorem proved that is the only way Schrodinger's Wave Equation can produce a probability without self contradictions. There are worlds where the scientific method would fail, for example there is a world where you flip a fair coin 1000 times and get heads each time, in such a world you would incorrectly conclude that the coin was not fair, but the square of the absolute value of the amplitude of such a world would be very small. So You're probably in a world where the scientific method works very well. > *always occur with probability one. * Probability is the wrong word to use in this case, a Everettian world either doesn't violate the laws of physics and thus exists or it does so it doesn't. However probability can be a useful concept in trying to figure out which world you're in.
