That doesn't address the point I'm making. Which is that if the universe can give rise to life, it's more likely to have multiple instances of it than for it to be exactly one. In the same way that it takes more effort to ensure you fill a swimming pool to be so full as to overrun by exactly one drop and no more, than it is to fill it imprecisely and either have no spillage at all because it's nowhere near full or lots of spillage because it's now too full.
- pfdietz 4y agoYou have to be careful to define "universe" here. It's not necessarily what we'd call the observable universe. It might, for example, be all the various branches of a universal wave function defining a vast array of possible universes, none of which could ever observe the others. It could also include sections of space time forever beyond our observational horizon (due to the apparently nonzero cosmological constant.) ET intelligences arising in those inaccessible places would never be able to land here on Earth.
