re: There is a much more powerful particle accelerator sitting in the center of the Milky Way galaxy
let's not mess about with small fish here. Making little circles on the earth is old hat.
I propose the Equatorial Particle accellerator, with a tube girdling the earth at the equator. 6371 km in radius, 40,000 odd km in circumference.
of course, there would have to be corrections for the particle streams to account for earth's rotation, but that's easily done...
