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 ...

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 ...

Researchers present the most precise test yet of the weak equivalence principle, a key component of the theory of general relativity. The report describes the final results from the MICROSCOPE mission ...

The European Space Agency (ESA) has launched one of its most precise science experiments to date — the Atomic Clock Ensemble in Space (ACES)—to the International Space Station (ISS). This is no ...

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 ...

Physicists are close to performing the most accurate tests of Einstein’s ideas about gravity ever undertaken. Their first-of-its-kind experiment involves using two kinds of extremely cold atoms aboard ...

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 ...

"Studying the rate at which galaxies formed lets us directly test our theories and, so far, we’re lining up with what general relativity predicts at cosmological scales." When you purchase through ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Two cutting-edge atomic clocks — the most accurate ever ...

In new studies published in Physical Review Letters and a special issue of Classical and Quantum Gravity on September 14, a team of researchers present the most precise test yet of the Weak ...
