Weighty thoughts on antimatter
A pulse of particles speeds into the vacuum chamber. Positrons, 20,000,000 antimatter particles, clumped in a pulse one nanosecond deep. Like a silent, angry swarm they are targeted into a porous silica target. The positrons are confined by a magnetic field, increasing their interaction with the silica. Some attract electrons and synthesize into positronium, a…
