Proponents of the multiverse idea must show that, among the rare universes that support life, ours is statistically typical. The exact dose of vacuum energy, the precise mass of our underweight Higgs boson, and other anomalies must have high odds within the subset of habitable universes.

In a Multiverse, What Are the Odds? | SOMEONE SOMEWHERE
Testing the multiverse hypothesis requires measuring whether our universe is statistically typical among the infinite variety of universes. But infinity does a number on statistics. 20 The theory of eternal inflation casts our universe as one of countless bubbles in an eternally frothing sea. If modern physics is to be believed, we shouldn’t be here.…
Roger Penrose of Oxford University has calculated that the odds of our universe’s low entropy condition obtaining by chance alone are on the order of 1:10 123, an inconceivable number. If our cosmos were indeed but one member of a much vaster multiverse of randomly ordered worlds, then it is vastly more probable that we should be observing a much smaller universe.
Eternal inflation predicts that our observable universe lies within a bubble (or pocket universe) embedded in a volume of inflating space. The interior of the bubble undergoes inflation and standard cosmology, while the bubble walls expand outward and collide with other neighboring bubbles. The collisions provide either an opportunity to make a direct observation of the multiverse or, if they ...

Our Improbable Existence Is No Evidence for a Multiverse ...
The physicist Lee Smolin has calculated that the odds of life-compatible numbers coming up by chance is 1 in 10 229. Physicists refer to this discovery as the “fine-tuning” of physics for life ...

What Is (And Isn't) Scientific About The Multiverse
As I've explained before, the Multiverse is not a scientific theory on its own. Rather, it’s a theoretical consequence of the laws of physics as they’re best understood today.
