In 1919, a total solar eclipse offered the only chance to test Albert Einstein's radical new theory of gravity, General ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

Scientists detect a 20-day wobble from a star-shredding black hole, confirming spacetime twisting predicted by Einstein.

The speed of light has been one of science’s most trusted markers of stability. For more than a century, the idea that light moves through space at a constant speed has supported some of physics’ most ...

For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth ...

Theoretical physicist and Nobel Prize winner, Kip Thorne, came to the BYU campus to lecture about his discoveries and ...

Researchers at TU Wien have integrated quantum physics with general relativity, revealing significant departures from ...

The seventh day of the 18th annual Space Telescope Advent Calendar features a distant galaxy seen through a patch of space ...

A radical new theory begins with a central claim: consciousness is the fundamental field of reality; time, space, and matter ...

The surface of Earth is finite. We can measure it. If it was expanding, then its size would grow with time. And once again, good ol' Earth helps us understand what the universe might be doing beyond ...

Is the universe infinite? It's one of the most profound questions we can ask, and here's the short answer: We don't know. While we have learned a great deal about the universe, a portion of the cosmos ...

By studying faint distortions in galaxy shapes across a vast region of sky, scientists probed the hidden structure of the universe. In the standard picture of the universe, nearly everything is hidden ...
