Explore the physics behind traveling from the Earth to the Moon and discover where gravity effectively becomes zero. Learn how gravitational forces balance, why astronauts feel weightless, and how ...

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

Thanks to not-so-recent advances in technology, we can shoot just about anything into space, or at the very least into Earth's orbit. At first, we launched spy satellites during the Cold War, but once ...

Try as they might, scientists can’t truly rid a space or an object of its energy. But what “zero-point energy” really means ...

The LIGO gravitational wave observatory in the United States is so sensitive to vibrations it can detect the tiny ripples in space-time called gravitational waves. These waves are caused by colliding ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. A newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...
