The drawings we make about it are awful. But it’s basically chemistry moreso than quantum physics.

Quantum foam is “iffy science. I like the idea of quantum foam but I saw a couple of studies that put some severe doubt on quantum foam.

Ask yourself: Is spacetime “grainy”?

I personally “believe in” quantum foam but it’s an article of faith. I like the idea of variable speeds of light (Wheeler) and loop quantum gravity (a newer spin foam model).

Yet I have to ask myself: Is this not a new version of “the aether”?

I want to believe in quantum foam but so far, experiments seem to show that the speed of light is annoyingly consistent even across long stretches of spacetime.

So, I leave such “nothing to something” notions as a fantastical science fiction/religious category and instead focus on what we *do* know scientifically: photons are a product of matter.

====

While the quantum foam model comes and goes in popularity, the generalized idea is pretty stable:

All is spacetime. There’s no “nothing” per se.

There’s “stuff” everywhere you go. Pick any voxel of space over time and you’ll never find nothing there.
