The ALPHA experiment at CERN is attempting a direct measurement of the mass of anti-hydrogen by trapping atoms of the stuff in a penning trap at high vacuum. The answer isn’t definitive yet as the error bars are huge and extend past zero, but are centered on the positive side. -Bill > mix 1 atom of hydrogen + 1 of anti hydrogen & you end up with 0 mass (+ > LOTTS of energy) > > To be honest it is all over my head > > > > -- > I used to be Snow White, but I drifted. > -- Mae West > -- > https://mail.python.org/mailman/listinfo/python-list -- https://mail.python.org/mailman/listinfo/python-list
