The NASA Eagleworks Laboratory team even put forward a hypothesis for how the EM Drive could produce thrust – something that seems impossible according to our current understanding of the laws of physics.
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.

This is yuge.
YUGE, I tells ya!
"bounces back and forth" reminds me of an excellent time-travelerish movie, Primer.
The EM drive may work, however, I don't think you can scale it and get any meaningful thrust out of it. I don't even think you can pop popcorn with it either.
