The rapid expansion of the universe has been the most perplexing enigma in physics. To unravel this cosmic puzzle, scientists turn to the fundamental laws of physics, including Albert Einstein's ...

COLUMBIA, Mo. – Scientists have attempted to disprove Albert Einstein’s theory of general relativity for the better part of a century. After testing and confirming Einstein’s prediction in 2002 that ...

The fabric of space and time is not exempt from the effects of gravity. Plop in a mass and space-time curves around it, not dissimilar to what happens when you put a bowling ball on a trampoline. This ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Black holes, regions of spacetime in which gravity is so strong that nothing can escape, are intriguing and extensively ...

Albert Einstein's general theory of relativity describes gravity as the warping of space-time geometry by mass, a concept distinct from Isaac Newton's absolute space and time, and has been empirically ...

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 ...

The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...

Earth’s mass and rotation affect the fabric of space and time. “This NASA mission is the culmination of 45 years of work at Stanford ...

The accelerating expansion of the Universe has puzzled scientists since its discovery in 1998. This phenomenon, one of the ...

Albert Einstein changed science forever with special and general relativity, redefining space, time, and gravity. Yet after his greatest triumphs, he became obsessed with something even bigger — a ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...
