For decades physicists have been perplexed about why our cosmos appears to have been precisely tuned to foster intelligent life. It is widely thought that if the values of certain physical parameters, such as the masses of elementary particles, were tweaked, even slightly, it would have prevented the formation of the components necessary for life in the universe—including planets, stars, and galaxies. A claim against this will undermine a major argument in support of the existence of a multiverse of parallel universes.

I’m not making a claim it is. What I’m saying is it’s ignored that it does appear to be. And it’s not something that should be just hand waved away.
