[quote] The AEGIS experiment plans to make the first direct measurement of Earth’s gravitational effect on antimatter. By sending a beam of antihydrogen atoms through very thin gratings, the experiment will measure how far the antihydrogen atoms fall during their horizontal flight. Combining this with the time each atom takes to fly and fall, the AEGIS team can determine the strength of the gravitational force between the Earth and the antihydrogen atoms.

I know what [del]some[/del] most of those words mean!
Sounds to me like they want to see if Earths gravity affects Antihydrogen by attracting it, like matter attracts matter, or repulses it. I think i read somewhere a while back that antiatoms should be repulsed by gravity Then again, This is mostly a guess so it's entirely possible i'm wrong in every way
[QUOTE]AEGIS team can determine the strength of the gravitational force between the Earth and the antihydrogen atoms.[/QUOTE] But why would it be any different from the force between the Earth and normal matter? I mean, if it was affected differently, then gravity would not be indistinguishable from a constantly-accelerating plane of reference, which is one of the predictions of Relativity. That, or antimatter would accelerate differently, and I think we would've noticed that in particle accelerators.

Aren't antiparticles supposed to be the same as "regular" particles except in charge and their penchant for doing silly things with "normal" matter? We know they have the same mass.
Seems like a waste of time considering what Eudoxia said if so much is similar and there isn't any giant distinction.
They most likely have their reasons, but the article didn't explain enough
