Elon Musk has called antimatter power ‘the ticket for interstellar journeys’; and physicists are exploring how to harness it.

Summary

  1. Antimatter is made up of particles almost like regular matter, but with opposite electric charge.
  2. When antimatter contacts regular matter, they can produce enormous amounts of energy.
  3. An antimatter engine could theoretically get us to Proxima in just five years.
