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.

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 ...

Don't miss out on the headlines from Space. Followed categories will be added to My News. Travelling at such speeds, the theoretical machine could carry astronauts to Mars in less than 13 minutes, or ...

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 ...

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 ...

A NASA engineer has proposed an alternative for space travel that could send a craft hurdling through space 'close to light speed'. Called a helical engine, this concept suggests pushing a particle ...

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 ...

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 ...

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 ...
