“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 ...

The question of how gravity interacts with the quantum world has long perplexed physicists, but a non-quantum theory of space ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity ...

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, ...

Thanks to the Event Horion Telescope, we now know black holes exist, but a new study published recently in Physical Review D ...

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 ...

Einstein's theory of general relativity predicts that massive objects warp the space-time around them. NASA's Gravity Probe B found that the space-time around Earth is indeed curved by our planet, and ...

General relativity (GR) is the geometrical theory of gravitation published by Albert Einstein in 1915. It unifies special relativity and Sir Isaac Newton's law of universal gravitation with the ...
