Learn how researchers used Einstein’s theory of general relativity to create the most accurate simulations to date.

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 ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

Learn how Albert Einstein’s theory reveals that time on Mars runs faster than on Earth — and why that tiny shift matters for ...

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 ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet their unification remains one of science’s greatest challenges. Now, ...

This temporal lag is a direct consequence of Albert Einstein’s Theory of General Relativity. The rule is simple: the weaker ...

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

If you're going to Mars you'd best take along a jar of anti-aging cream because while you're there you're going to age faster ...

The only known duo of pulsars has just revealed a one-of-a-kind heap of cosmic insights. For over 16 years, scientists have been observing the pair of pulsars, neutron stars that appear to pulsate.

Like Max Planck, Albert Einstein first studied mathematics because he was told that everything interesting in physics had already been discovered. But in 1905, Einstein, a young cleark at the Swiss ...
