This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

For more than a century, gravity has been the immovable backdrop of modern physics, a force that can be described and ...

Over the last few years, we’ve heard a lot about the EmDrive NASA has been working on at its Eagleworks lab under the direction of Doctor Harold White. Also known as the EM Drive, the EmDrive is based ...

In major international tests, the physics-defying EmDrive has failed to produce the amount of thrust proponents were expecting. In fact, in one test at Germany’s Dresden University, it didn’t produce ...

One of the ultimate dreams of humans everywhere is limitless, free energy. It's the ability to do the impossible: to pull power out of empty space itself; to create a device that spins ...

Documents were leaked earlier this month about NASA’s study of a proposed EmDrive. It generated the usual host of reactions, ranging from “it totally works” hype to outright dismissal. It’s rare for a ...

The keys to EMDrive experiments are prove the propulsion is real and will work in space. Find a way with theory or experiment to scale up the effect. If it is real and the effect can be scaled up then ...

Since the birth of the space age, the dream of catching a ride to another solar system has been hobbled by the “tyranny of the rocket equation,” which sets hard limits on the speed and size of the ...
