What would be the state of a universe that contains only antimatter? Is it in a state of contraction or expansion similar to ours?
As what Feynman diagram shows antiparticles travel backward in time, so if we can transform ordinary matter into antimatter by changing the protons to antiprotons, neutrons to antineutrons, and electrons to positrons, the new form of matter will travel backward in time. So a time machine is really a matter-antimatter converter.
