For nearly 20 years, scientists have debated the viability of an EmDrive, a hypothetical type of engine that could propel a spacecraft without the need for any fuel. Now, a team of German physicists ...

George Hathaway provides a detailed analysis of the EMDrive and the recent peer reviewed research paper that measured some thrust and tried to eliminate sources of ...

On 17 November 2016, a team of engineers from an experimental research group (nicknamed Eagleworks Laboratories) at NASA’s Johnson Space Center published the results of a test purporting to ...

A radio frequency (RF) resonant cavity thruster is a proposed type of electromagnetic thruster. Unlike conventional electromagnetic thrusters, a resonant cavity thruster uses no reaction mass and ...

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 ...

Given fuel usually makes up the majority of the mass of any spacecraft trying to break the bonds of gravity, developing propellantless propulsion systems might be the key we need to really open up ...

Researchers at NASA's Eagleworks advanced-propulsion lab have been working on a technology that can theoretically bring humans to Mars in just 70 days. The rocket propulsion engine known as EmDrive is ...

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 ...

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 ...

Two German researchers claim they have produced measurable amounts of thrust using a copy of NASA’s controversial EMDrive. It’s a result that has many people talking, but don’t plan your trip to the ...

More experiments on the much-overhyped EMDrive continue to prove absolutely nothing except that it’s easy to create ambiguous results if you’re sufficiently sloppy with your experimental design.

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Imagine a rocket that works without fuel. You pump energy into it and ...
