Scientists keep discovering the number 10^122 occurring in mathematical relationships in the natural world [hat tip: GeekPress]. The last time
this happened, it was when 10^4 kept appearing in both electromagnetic and strong/weak nuclear contexts, and it turns out
that it signaled a common relationship between the two. So scientists are concluding that the best explanation is some common, underlying factor
that explains why the same ratio keeps coming up.

Now here's what I'm wondering. If we're just one universe among a huge number, and the constants in each universe are different, then we just happen to be the universe with these constants. So why assume some common explanation for why the constants are the ones we've got? Doesn't the multiple universe explanation make the search for a common explanation otiose? At least that's what you'll hear if you try to make an inference to the best explanation when the constants happen to be in the narrow range that allow for the development of life. So what's different about this inference to the best explanation when both arguments involve what cosmological constants we happen to find ourselves with?
