Learn how gravity and mass are pulling two stars into tighter, faster orbit around each other, with an explosive collision ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy.

Could a reactionless, gravity-defying propulsion system actually work? A former NASA engineer says yes, but scientists are ...

This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

Muscle mass decreases due to decreased use and a lack of stimulus through exercise equipment, and bone loss occurs while ...

Webb captured an Einstein ring formed by a distant galaxy's light bending around a closer one. This rare alignment magnifies ...

A newly published study in the Journal of Cosmology and Astroparticle Physics JCAP has not detected any signals attributable to quantum gravity effects in the neutrinos observed by the underwater ...
