Antimatter atoms can be precisely manipulated and cooled with lasers
Let me know when they can make a Bose-Einstein Condensate out of them.
. . . don't see why not :
@FearlessFly Yeah, that one sounds like straight rocket fuel. Electrons & positrons annihilate to yield 511 keV each. (I once made Fluorine 20 which decayed to Neon. It came out of the pneumatic too hot to handle, then we had to run to the detector before it all disappeared...
Positrons occur naturally in inverse beta decay so they would have been found even if antimatter hadn't already been predicted to exist.
