British inventor Roger Shawyer proposed the EM Drive or Electromagnetic Drive in 1999. It was the best way to travel to Mars and other space destinations, except for one thing—it broke Newton's Third Law of Thermodynamics: every action has an equal and opposite reaction.
NASA has finally peer reviewed the EM Drive and, hokey smokes, it works! Leave it to science to continually defy its own laws to reinvent itself. More evidence that the universe is "stranger than we can imagine."
