'Impossible' rocket drive works and could get to Moon in four hours.

The British designed EM Drive actually works and would dramatically speed up space travel, scientists have confirmed

Interplanetary travel could be a step closer after scientist confirmed that an electromagnetic propulsion drive, which is fast enough to get to Moon in four hours, actually works.

The EM drive was developed by the British inventor Roger Shawyer nearly 15 years ago but was ridiculed at the time as being scientifically impossible.It produces thrust by using solar power to generate multiple microwaves that move back and forth in an enclosed chamber.This means that until something fails or wears down, theoretically the engine could keep running forever without the need for rocket fuel.

The drive, which has been linked to Star Trek's Impulse Drive, has ledt scientist scratching their heads because it defies one of the fundamental concepts of physics - the conservation of momentum - which states that if something is propelled forward, something must be pushed in the opposite direction.So the force inside the chamber should cancel each other out. 

However in recent years Nasa has confirmed that they believe it works and this week Martin Tajmar, a professor and chair for Space Systems at Dresden University of Technology in Germany also showed that it produces thrust.The drive is capable of producing thrust several thousand time greater than a standard photon rocket and could get to Mars within 70 days or Pluto in 18 months. A trip to Alpha Centauri, which could take tens of thousands of years to reach right now,could be reached in just 100 years.

"Our test campaign cannot confirm or refute the claims of the EM Drive but intends to independently assess possible side-effects in the measurments methods used so far. "said Prod Tajmar in anew

"Nevertheless, we do observe thrust close to actual predictions after eliminating many possible error sources that should warrant further investigation into the phenomenon."

"Our measurements reveal thrust as expected from previous claims after carefully studying thermal and electromagnetic interferences. 

"If true, this could certainly revolutionize space travel."

Shawyer also claims that he is just a few months away from publishing new results confirming that his  drive works in a peer reviewed journal.

However scientist still have no idea how it actually works. Nasa suggested that it could have something to do with the technology manipulating subatomic particles  which constantly pop in and out of existence in empty space.

Prof Tajmar presented his findings to the 2015 American Institute for Aeronautics and Astronautics' Propulsion and Energy Forum and Exposition this Week.
