Do you remember the scenes in sci-fi films like Star Wars or Star Trek where spaceships vanish in space when they travel? In these films, spaceships go into a vacuum, where it moves faster than the speed of light. We know, it defied the laws of physics. But just recently, NASA confirms it's possible! This engine that they've been studying for so long, which they call EmDrive somewhat does the same!
Experts at NASA can't believe it, too. They say it's impossible, but the results tell otherwise.

A maverick research team at NASA’s Johnson Space Center formally published the evidence
of this milestone. An electromagnetic propulsion system enabled spacecrafts to travel through void without the need of any propellant.
The team calls it, electromagnetic drive or EmDrive, which uses electricity to initiate a thrust into a hole of closed cavity. The spacecraft technically moves by bouncing around microwaves in a vacuum. Theories of experts claim it will let humans travel to Mars in just 70 days!
However, skeptics still can't believe, saying it defies the law of physics.
Newton’s third law, if you remember, states that for every action, there is an equal and opposing reaction. EmDrive, makes travelling a lot faster by going into a vacuum, which clearly breaks this law from Sir Isaac Newton.
EmDrive came from the theory of British scientist Roger Shawyer, proposed 20 years ago. Engineers at NASA’s Advanced Propulsion Physics Research Laboratory, known as Eagleworks, embodied this theory by doing vigorous testing and development, and call it EmDrive.
Though, until today, it's not yet clear how the machine works, EmDrive is surely an achievement to spacecraft innovation. Experts still argue if it's just a part of pseudoscience, or a revolutionary discovery that would let humanity move forward to knowing the unknown.
I say, EmDrive is our key to get to Tatooine. Star Wars fans know it!
