DARPA gave researchers $1.3 million to build a prototype engine that is fueled by light.
German physicists launched the SpaceDrive project to explore possible sources of error in EmDrive experiments. Their first experiment identified a possible source of false positives in past successful EmDrive tests.
The EmDrive propulsion system might be able to take us to the stars, but first it must be reconciled with the laws of physics.
It's still not clear how it works, but pilot-wave theory may have something to do with it.
Mach effect pioneer James Woodward breaks down the significance of a leaked paper detailing the successful test run of NASA’s 'impossible engine.'
More problems with the EmDrive: As pitched, it's an "absurd" perpetual motion machine.
Imagine blasting through space without the need for extra fuel.
