Who needs the laws of physics, anyway? Not NASA. At least, that is what a new peer-reviewed paper indicates. The paper discusses what was a fuel-free rocket engine, which tests now show works. But how ...

If there’s one thing guaranteed to ruffle a few feathers, it’s surely the EM Drive. Billed in some corners as the holy grail of deep space travel, others (including us) have been quick to calm ...

At this point, the EM Drive will be important -- if not for revolutionizing space travel, then at least for dramatically illustrating the difficulty of taking accurate force measurements at extremely ...

A new theory of inertia could explain how NASA is generating thrust with a new drive design, and may even show them how to make it more powerful. Share on Facebook (opens in a new window) Share on X ...
