The folks who brought us QM and string theory do not shy away from dragons. There have never been bigger dragons in the history of thought. Someone needs another horse to ride. The shy one's been rode hard and put away wet.
Indeed, quantum mechanics and string theory was a bold move into the mysterious.
Years ago, the implication of a Big Bang (a beginning of time) was such a "dragons be there" issue that even Einstein kluged a cosmological constant to avoid it. Of course, later he withdrew that idea.
But even today, to avoid the implication of a beginning we are offered an assortment of multi-universe theories. I don’t object to the theories – except the ones that base the alternate universes on the physical laws of this one. It’s presumptuous per se and doesn’t resolve the anthropic principle. It is also ideology, the necessary conclusion of metaphysical naturalism.
There's a reason some theorists want other universes to exist: They believe it's the only way to explain why our own universe, whose physical laws are just right to allow life, happens to exist. According to the so-called anthropic principle, there are perhaps an infinite number of universes, each with its own set of physical laws. And one of them happens to be ours. That's much easier to believe, say the anthropic advocates, than a single universe “fine-tuned” for our existence.
