Over the last year, a number of researchers around the world have suggested that NASA’s controversial EM Drive might work after all. Tests done over the last two years at NASA’s Eagleworks Lab seem to indicate that thrust is being produced by this device without any propellant of any kind. Even the military is taking an interest.

The problem with the EM Drive is that it seems to contradict the known laws of physics – a point that has made most scientists reject the possibility that the EM Drive could actually work. According to Newtonian theory, all reactions require an equal and opposite reaction. But that doesn’t seem to be happening with the EM Drive.

But despite the skepticism of much of the scientific world, researchers from Europe to the United States and China have found small but consistent thrust being produced by this device – dare we say engine. But if the EM Drive functions as advertised, it could mean a revolution in space propulsion.

Today, space propulsion is dominated by chemical rockets that have to carry tons of fuel with them as they travel. This places a limitation on their speed and how much cargo they can carry. Without the necessity of carrying fuel along, a spacecraft equipped with an EM Drive and powered by solar panels or a nuclear reactor could travel ridiculously far and fast.

Currently, it takes anywhere from six months to two years to reach Mars from Earth. Calculations show an EM Drive equipped spacecraft – manned or unmanned – could reach Mars in 70 days or less. This is roughly equivalent to how long it took colonists on sailing ships to travel across the Atlantic to the New World. So this is literally a game changing technology – if it works.
