In an infinite multiverse, the need to calculate if our universe is typical leads directly to the devastating three-layered measure problem: ad hoc measures are bad ideas to begin with, all intuitive measures don’t work, and even if multiverse scientists were to find a contrived measure that did work, it would beg the question of what fine tuned and designed it?

While multiverse theory is plagued by many issues, the measure problem is unique. It conclusively demonstrates the multiverse’s failure to explain fine tuning and, for that matter, to explain anything at all. Once you understand the full scope of this problem, you’ll see why the multiverse fails as a good scientific theory, even in multiverse scientists’ framework.
