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

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

One of the most exciting questions, particularly when we are discovering that our planet is a ball, is, ‘Why don’t people on the bottom of the Earth f.

Often misunderstood as "hovering," satellites are actually in constant free-fall, perpetually missing Earth's surface as the ...

Earth and the Moon are forever locked in a gravitational embrace that has played a critical role in determining the fate of both worlds. Although they have grown more distant since their formative ...

Buckle up, nerds: NASA is building the first quantum gravity sensor for space—a suitcase-sized instrument that could soon be measuring everything from subterranean water to hidden reserves of ...

A patent has been filed for a space station concept that generates gravity by rotating its ring-like living quarters in Earth ...

The list of challenges space explorers will face is formidable. They'll have to produce breathable air, clean water, and food in extremely hostile environments lacking all of the above. They'll also ...

The proposed 1,300-foot-tall lunar structure would spin three times every minute, generating Earth-like gravity for its inhabitants. Reading time 2 minutes Interest in the Moon has been reignited ...

Discovering a machine that could somehow produce thrust without releasing propellant would be a game-changer for human space travel. There’s just one problem—such a device would defy the laws of ...
