Negative energy is almost certainly not a thing.

If two objects made up of matter and antimatter collide, they would annihilate each other and release all of their energy as an explosion

If two objects made of energy and anti-energy collided they would also annihilate each other… except there would be nothing afterwards. Total information loss as no energy would escape the impact, since there would be no more energy afterwards.

Yeah I’m inclined to agree.

If negative energy is somehow possible, it causes … an absurd number of paradoxes, very quickly, if it can just… exist, without bounds.

I am not any kind of actual physicist, but if I had to attempt to concieve of some framework where it even might be possible…

I’d go for some kind of 11, 12, whatever dimensional universe, when it would concievably be possible to have energy be able to bleed off in higher dimensions, which might kind of look like ‘negative energy’ to us 3D spacetime things, but actually wouldn’t be.

Of course… all of that is mind bogglingly complex as well, and probably causes paradoxes I am too ignorant to understand.

since energy is a property of matter rather than something on its own, it would be more like a totally inelastic collision.

but while we’re on sci-fi, what if negative enerfy is possible in a moving reference frame?

Wait.

Ok uh… what if…

What if anti-energy + energy = 50.0000…1% matter, and 49.9999…9% anti matter?

We… still don’t actually know why matter dominates the universe over anti-matter, right?

… just spitballing here.

Does that even … possibly make sense?

I don’t know.
