Some of the hardest questions in cosmology begin where the usual math gives up. Push Einstein’s theory far enough back toward ...

Sophia Varughese has two passions: astrophysics and music. Her senior thesis is a scholarly look at black holes and ...

For decades, one of the biggest questions in cosmology has remained frustratingly out of reach: what, if anything, existed ...

This November, Einstein’s theory of general relativity will celebrate its 100th anniversary. Despite its advanced years, Einstein’s soon-to-be centenarian theory is holding up remarkably well. That’s ...

In the hunt for extraterrestrial life, we usually look for planets orbiting sun-like stars and icy moons. But there is another possible candidate—planets circling white dwarfs, the hot, dense remnants ...

“The one sentence statement of general relativity is that ‘gravity is the curvature of spacetime,’” explains Dr. Sean Carroll, assistant professor of physics at the University of Chicago. “Really, the ...

Answering some of the biggest questions in astrophysics—for example, about black holes and the origin of the universe—might require overhauling general relativity. In this artist’s illustration, ...

General relativity has withstood perhaps its toughest challenge to date. The theory, which Albert Einstein published in 1916, revolutionized our understanding of physics and the cosmos. It explains ...

Albert Einstein's theory of general relativity has been proven right again — and this time, physicists have pinned down just how precise it is: Any deviations from his theory of general relativity are ...

While the equation E=mc 2 is famous throughout the world, it was just the first step in Albert Einstein’s discoveries. The formula, describing the relationship between energy and matter, laid the ...
