Like seriously, why the fuck are you following me, I'm not that interesting.

Identify yourselves stalkers!

Because "yer a peein"

So, my understanding of particle physics is rudementary at best, but I got to thinking that since anti particles are electrically opposite to normal particles, the electromechanical forces within an atom would be identical in magnitude if the charges were reversed. So theoretically there could be anti hydrogen, anti helium.etc. My question is, if a body in space was constructed of antimatter, how could we tell outside of sending normal matter and seeing if the sample gets annihilated.

All this is based on my assumption that anti atoms can exist, if they can't I would appreciate an explanation as to why.

I can't access it anymore and any comments made there aren't in my comment history. Anyone else?
