EM Drive (RF resonant cavity thruster)
The law of conservation of momentum says that a rocket (or anything else) can’t accelerate forward without some form of exhaust ejected backward. But in 1998, a British engineer named Roger Shawyer announced the seemingly impossible—he had built a closed system that could generate thrust.
