I’m reading Soylent News and come across the following.

If modern physics is to be believed, we shouldn’t be here. The meager dose of energy infusing empty space, which at higher levels would rip the cosmos apart, is a trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion times tinier than theory predicts. And the minuscule mass of the Higgs boson, whose relative smallness allows big structures such as galaxies and humans to form, falls roughly 100 quadrillion times short of expectations. Dialing up either of these constants even a little would render the universe unlivable.

To account for our incredible luck, leading cosmologists like Alan Guth and Stephen Hawking envision our universe as one of countless bubbles in an eternally frothing sea. This infinite “multiverse” would contain universes with constants tuned to any and all possible values, including some outliers, like ours, that have just the right properties to support life. In this scenario, our good luck is inevitable

Is that why they’ve postulated mutliple universes?

I realize Soylent News is not a physics textbook and that the poster could have got it wrong, but I can’t go look it up in source material. I wouldn’t understand a word of it.

But if that really is the thinking behind assuming multiverses, wouldn’t a much simpler explanation be that the current theories are missing vast aspects of the universe? Maybe we just don’t know everything yet. Human ignorance seems a much likelier explanation than multiverses. Or not?
