A long-awaited, peer-reviewed scientific paper has been published that indicates the controversial EM (Electromagnetic) Drive appears to work even though it apparently violates one of the laws of motion.

In case you’ve missed the hype, the EM Drive, or Electromagnetic Drive, is a propulsion system first proposed by British inventor Roger Shawyer back in 1999.

Instead of using heavy, inefficient rocket fuel, it bounces microwaves back and forth inside a cone-shaped metal cavity to generate thrust.

According to Shawyer’s calculations, the EM Drive could be so efficient that it could power us to Mars in just 70 days.

But, there’s a not-small problem with the system. It defies Newton’s third law, which states that everything must have an equal and opposite reaction….

Yet in test after test it continues to work. Last year, NASA’s Eagleworks Laboratory team got their hands on an EM Drive to try to figure out once and for all what was going on.

The new peer-reviewed paper is titled “Measurement of Impulsive Thrust from a Closed Radio-Frequency Cavity in Vacuum“, and has been published online as an open access ‘article in advance’ in the American Institute of Aeronautics and Astronautics (AIAA)’s Journal of Propulsion and Power. It’ll appear in the December print edition.
