| Oct 26, 2014 at 19:48 | comment | added | Kyle Kanos | It doesn't have to be H though, it could be any element or molecule--there's no reason why it would be a clump of only antiparticles. Anyways, this actually appears to be more-or-less a duplicate of physics.stackexchange.com/q/26397 and/or physics.stackexchange.com/q/1165 | |
| Oct 26, 2014 at 19:43 | comment | added | William Grunow | Well assuming that there is significant Anti-Hydrogen somewhere in the universe, that region would be void of Hydrogen presumably. | |
| Oct 26, 2014 at 19:28 | comment | added | Kyle Kanos | $\bar{\rm H}+\rm H$ interactions (e.g., collisions) lead to gamma rays whereas $\rm H+H$ does not. Not sure if there are ways to determine the difference between $\bar{\rm H}$ and $\rm H$ without interactions though. | |
