Re: Anti-matter

["William J. Larson" <Bill_Larson@compuserve.com>]

I'm not aware of experimental evidenve of the gravitational properties =

of antimatter.  Since gravity is so weak this is a very hard experiment =

to do.   Has it been done and I missed it?  Until experiment speaks,
theorists must remind themselves, they really know nothing about
the gravitational properties of antimatter.  Nature is under no constrain=
t
to be the way we imagine it should be.

particle.  The gravitational "field" would be the same and antiparticles
move along geodesics just as well as particles.
