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 ...

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 ...

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 ...

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 ...

Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of Ask a Spaceman and Space Radio, and author of How to Die in Space. He contributed this article to ...

Dr Jose Rodal posted on the NASA Spaceflight forum that the new paper will be entitled “Measurement of Impulsive Thrust from a Closed Radio Frequency Cavity in Vacuum” and is authored by “Harold White ...

This is a guest post by David Hambling, a freelance journalist and author based in South London, specialising in science, technology and strange phenomena. Martin Tajmar, professor and chair for Space ...

Here's a hint: It's a spaceship engine... that needs no fuel to operate. NASA is going to Mars, perhaps as early as 2033. It won't be a short trip, however, at least not with current technology. One ...

After years of unwarranted hype and dubious experimental claims, the EmDrive, an “impossible” propulsion device that claims to produce thrust while violating Newton’s Laws of Motion, has received its ...

A lingering, improbable concept called the EmDrive says it moves itself without fuel. DARPA funding caused a fresh news cycle and drew attention to the inexplicable design. Momentum without a catalyst ...
