“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.

I don't think so. Remember: This is energy being converted to mass, not mass coming out of nowhere.

Ah right. So, an alternative to dark energy and dark mass?

[–] NoneOfUrBusiness@kbin.social 2 points 6 months ago

No no that's a completely different phenomenon. This is the phenomenon involved in Hawking's radiation and similar.

Correct me if I am wrong, but as I understand it mass and energy is equivalent no? And it also still baffles us as to why rest mass and resultant mass from energy should be equivalent at all?

Yes.

I don't know about this one. I'm not an expert so don't quote he on it, but I don't remember hearing this before.

Then why wouldn't it exert gravitational force?

[–] NoneOfUrBusiness@kbin.social 2 points 6 months ago (1 children)

It does, but that's the thing: It does either way. There should be no change due to the conversion of energy to mass.

Ahh, I see what you mean. Thanks for explaining it
