It is quite true that many scientists, many physicists, maintain that the physical constants, the half dozen or so numbers that physicists have to simply assume in order to derive the rest of their understanding ... have to be assumed. You can't provide a rationale for why those numbers are there. Physicists have calculated that if any of these numbers was a little bit different, the universe as we know it wouldn't exist.
