Groundbreaking Propulsion Method Using Relativistic Electron Beams Could Enable Interstellar Travel

A new propulsion method, using relativistic electron beams, could make interstellar travel feasible within a human lifetime. Researchers Jeff Greason and Gerrit Bruhaug have proposed accelerating electrons to near light speed to deliver kinetic energy to spacecraft. This method could enable probes to reach 10% of the speed of light, drastically reducing travel time to…
