From the fall of an apple to the glow of the farthest known star, gravity quietly choreographs almost everything that happens in the cosmos. It shapes planets and people, bends light into celestial ...
Gravity, as most people understand it, is the familiar force that pulls a falling apple toward Earth. But for astronomers and ...
To understand gravity, Einstein had to rethink space and time as a single connected fabric. He showed that mass bends this fabric, guiding how everything moves. NOVA is available to stream on pbs.org ...
Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen. In 1935, ...
Astronomers have long been puzzled by a cosmic mystery: planets orbiting two stars—like Star Wars’ Tatooine—are surprisingly rare, even though they should be common. New research suggests the culprit ...
A century ago, Edwin Hubble began the race to the edge of the cosmos Damond Benningfield In 1930, Albert Einstein met with astronomers (including Edwin Hubble, at Einstein's left, back row) at Mount ...

The faster you move, the stranger time becomes. By imagining how light travels to two people moving at different speeds, Einstein showed that time isn’t absolute. His thought experiment revealed that ...
What if the technology you use every day depends on a subtle distortion of time itself? The answer lies in a century-old idea ...
