Gotcha, makes sense. Are we sure the density of the intergalactic medium is high enough to make interactions between matter and antimatter produce light visible

Gotcha, makes sense. Are we sure the density of the intergalactic medium is high enough to make interactions between matter and antimatter produce light visible from long distances, though?
- danbruc 10y agoWe have bounds on the density near such boundaries and their distance from Earth above which they would become visible.
