The MICROSCOPE mission tested the weak equivalence principle with free-falling objects in a satellite. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

Einstein’s Theory of General Relativity is currently our best approximation of how the universe ticks. But there are holes.

Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another. When you purchase through ...

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 ...

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 ...

Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of ...

An international team led by Japanese researchers has made a 3D map of 3000 galaxies 13 billion light years from Earth, and found that Einstein’s general theory of relativity is still valid. Since it ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

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 ...
