If it's antimatter why isn't it coalesced into antigalaxies that we would be able to see visibly, and is instead diffused as a dark fluid?

- excalibur 8y agoIt is, we can't see them because they emit dark energy "light". /s
- garmaine 8y agoWe would see gamma radiation producing events at the interaction interface, even if it is just interstellar gas occasionally colliding. Not to mention the occasional universe bleaching bursts of energy that comes from an antimatter galaxy colliding with a regular matter galaxy.

- delecti 8y agoI know you put the "/s", but in case anyone isn't aware, as far as we know the photon is its own anti-particle. So light from anti-matter stars would still just be light.
- Filligree 8y agoGiven the spacetime interval between photon creation and destruction is always zero, I'd find it moderately bizarre if there was an antimatter version of them.
- mrfusion 8y agoThey could repel each other gravitationally too. Seems like that’s how antigravity would would work. I don’t even think we know that about antimatter yet.
