This concept could eventually lead to a laser-firing satellite that could get rid of a large percentage of the most troublesome space junk orbiting Earth, scientists added.

Last year, NASA's advanced propulsion research wing made headlines by announcing the successful test of a physics-defying electromagnetic drive, or EM drive. Now, this futuristic engine, which could in theory propel objects to near-relativistic speeds, has been shown to work inside a space-like vacuum.
