This is very cool. Scientists have successfully tested an engine with an electromagnetic propulsion drive, or the EM Drive, that could conceivably take humans to Mars in just 70 days. The EM Drive works in a vacuum that replicates space. This breakthrough has gotten comparatively little attention despite its transformative impact on space travel.
This is still an early stage but the potential for the EM Drive is amazing. Indeed, it seems to defy a fundamental concept of physics involving the conservation of momentum — that for something to be propelled forward, it needs some kind of propellant to be pushed out in the opposite direction. The EM Drive simply uses electromagnetic waves.
Can you say warp drive?
