The physical laws of our current universe are suspiciously finetuned for life to exist

Confirmation of a multiverse could raise some intriguing questions about the origins of life and our own place in the cosmos. According to our current understanding, the physical laws of our universe are suspiciously fine-tuned for life to arise – atiny difference in any one of several physical constants might make liquid water much rarer, render complex organic chemistry unworkable or leave matter itself unable to hold together. The usual scientific solution to this problem, called the ‘weak anthropic principle’, simply states that if the laws of the universe didn’t have the particular behaviours we observe, we wouldn’t be around to see them, so we shouldn’t be so surprised. ‘Strong anthropic principles’ take things a step further with the assumption that, for some reason, the universe has to give rise to something like its present set of life-friendly parameters, perhaps even because the existence of conscious observers is a requirement for the universe to exist.
