Reply to comment by -domi- in A first-of-its-kind experiment simulating the cosmos with ultracold potassium atoms suggests that in a curved, expanding universe pairs of particles pop up out of empty space by marketrent
Negative/positive particle pairs don’t break any laws because there is no net energy change

Most particles don't have zero mass, so the energy also has to come from somewhere.

Ground state fluctuations generate the paired particles.

Surely, that's a change in entropy going to wrong way, though? Do we have any other evidence of materializing matter for free at zero energy investment? What about mass?

It’s not a zero investment - the energy comes from the ground state so-called “zero point” energy
