Re: Matter/anti-matter asymmetry

There's even a possibility that there is no asymmetry. That is,
distant parts of the universe are made of antimatter. They
would have to be remote enough that we wouldn't see the
characteristic annihilation signature at the interface between
the regions, but other than that the physics would be the
same. There is an experiment known as the AMS experiment,

Surely there would be some sort of gamma ray background produced as
annilation took place. Also the asymmetry has been observed with
particle accelerators here on earth, so if there is no asymmetry it
will mean that the asymmetry observed is caused by matter itself.

BTW - The experiment would be done far better on a dedicated unmanned
satellite. Please do not try and justify the Molloch that is destroying
all space science. See
