The results of these experiments indirectly tell us something about our chances of ever meeting aliens:
* No physical collapse => Everett interpretation AKA "many worlds"
* Many worlds gives us the Anthropic Principle for free
* The Anthropic Principle explains the origin of the first living organism, or, to put it another way, the observed existence of the origin of our first living ancestor does _not_ set any lower bound on the probability of the first living organism developing from non-living molecules.
* A very low probability of the origin of life implies the non-existence of any other life in the observable universe.
* Therefore, no aliens.
(The aliens do of course exist in other parts of the total Universal Wave Function, but we never get to meet them.)
