Ethan Siegel: How we can get a universe from nothing?

possible evidence for dark energy/NASA, CXC, SAO, A.Vikhlinin et al.

He brings in dark energy:

So why do we say we have a Universe that came from nothing? Because the value of dark energy may have been much higher in the distant past: before the hot Big Bang. A Universe with a very large amount of dark energy in it will behave identically to a Universe undergoing cosmic inflation. In order for inflation to end, that energy has to get converted into matter and radiation. The evidence strongly points to that happening some 13.8 billion years ago.

When it did, though, a small amount of dark energy remained behind. Why? Because the zero-point energy of the quantum fields in our Universe isn’t zero, but a finite, greater-than-zero value.

Well then, dark energy better exist or his theory is in trouble.

    Cool if he’s got the mechanics to get something out of something because dark matter has to exist and dark energy which is still something. I’m sure he can replicate this and create the universe

    News, Siegel has relabelled something as no-thing, properly — non-being. A basic error. There is no good warrant that some quantum foam will credibly toss up a fine tuned cosmos with responsible rational (not merely computational) morally governed creatures in it. He and others of like view need to explain why we have an actual world instead of a Boltzmann brain or simulation world. KF
