NASA engineer David Burns used special theory of relativity to devise a 'helical engine ' that could theoretically accelerate to 99% of the speed of light. The mechanism of the helical engine itself ...

Trying to fathom the concept of a light-year is not by any means easy - it’s literally how far light travels in a year, roughly 9,460 billion kilometers or 5,880 billion miles. That’s a lot of zeros.

New Scientist is reporting that NASA engineer David Burns is making some bold claims about a conceptual new spaceship thruster he calls the “helical engine” — a concept the magazine admits “may ...

Spacecrafts of the future could be propelled by in-space engines that require zero fuel, if one engineer’s proposal comes to fruition. David Burns, an engineer based at NASA’s Marshall Space Flight ...

A NASA scientist has cooked up plans for a bonkers new rocket engine that can reach close to the speed of light – without using any fuel. Travelling at such speeds, the theoretical machine could carry ...

The NASA Marshall Space Flight Centre engineer has advanced an alternative to traditional fuel for propelling rockets through space. This is a huge, helix-shaped engine powered by a particle ...

David Burns’s idea for a “helical engine” with no propellant is ingenious (19 October, p 15). He imagines a movable ring, whose mass is much greater when it slides in one direction than the other. But ...

An engineer who works for NASA has put forward a proposal for a new way to travel through interstellar space—a "helical engine" that could, potentially, push a spacecraft forward without the need for ...
