Physicists have chased a unified description of nature for more than a century, yet quantum theory and gravity have ...

Gravity is big and weird and difficult to study. It moves through space as a wave, sort of like how light does. But these waves are subtle and difficult to detect. They occur in measurable amounts ...

General relativity describes gravitation in a geometrical framework generalizing special relativity and classical mechanics. This term includes theoretical studies of gravity, experimental studies of ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists from ...

Albert Einstein’s mind reinvented space and time, foretelling a universe so bizarre and grand that it has challenged the limits of human imagination. An idea born in a Swiss patent office that evolved ...

When I was five years old, my family moved into a 1930s semi-detached house with a long strip of garden. At the end of the garden was a miniature orchard of eight apple trees the previous owners had ...

How confusing inevitability with reality built decades of paradox. What if general relativity never actually tells us that ...

One day, a mind-bending device called the gravity telescope might bring us visceral pictures of exoplanets far beyond our solar system. Monisha Ravisetti was a science writer at CNET. She covered ...

In many universes, typically those on TV shows or in movies, time travel is not much more difficult than driving downtown in any major city during rush hour. Sure, the traffic can get gnarly, but no ...
