In 2014, no less an authority than NASA proclaimed in peer-reviewed papers that it was getting mysterious thrust from the EmDrive, a strange, brassy trumpet of a thing that its creators claimed could ...

Imagine if, after the Wright Brothers made their historic first flight in 1903, they had met with complete skepticism, because the scientific establishment did not believe that heavier-than-air flight ...

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 ...

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 ...

The "EmDrive" claims to make the impossible possible: a method of pushing spacecraft around without the need for — well, pushing. No propulsion. No exhaust. Just plug it in, fire it up and you can ...

Proponents of the EmDrive are still trying to demonstrate it can work, but evidence remains thin on the ground despite a new report. The problem with the design -- the fact that it violates the laws ...
