“Nothing” doesn’t exist. Instead, there is “quantum foam” (bigthink.com)

So I wonder, even if it's only appearing very briefly it's still going to exert some small gravitational effect. And who is to say the density of quantum foam is perfectly evenly distributed through the universe, within, through and between galaxies? Could this be an alternative explanation to dark matter?

Would be nice if we could measure quantum-foam activity depending on gravity well intensity. Let's say somewhere around Venus and Pluto to compare (sun's well).

I think Wikipedia articles about zero-point energy and quantum-foam explain this well.

Btw, wasn't there an experiment with a laser vibrating a nano-particle with nearly lightspeed, separating the particle & anti-particle pair before annihilation, creating matter from nothing?

Ah, btw, Casimir effect.
