This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

Could a reactionless, gravity-defying propulsion system actually work? A former NASA engineer says yes, but scientists are ...

Smaller bodies of water, like lakes and pools, don't have noticeable tidal bulges because they lack enough liquid to create pressure that can visibly overcome the pull of Earth's gravity.

For over half a century, scientists suspected a quiet but powerful electric field might be influencing Earth’s upper ...

NASA’s AWE mission just released millions of gravity wave images from space, unveiling atmospheric forces that ripple through ...

NASA identifies five significant risks that could hinder a successful manned mission to Mars, including cosmic radiation and ...

Getting high enough to escape Earth's atmosphere takesa massive amount ... So gravity pulls everything downwards,all the time, but we can overcome gravity if we have enough force inthe opposite ...
