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 ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Time feels like the most familiar thing in the world, yet it hides one of physics’ hardest questions: why do we only remember ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths ...

Physicists from JILA — a CU Boulder and National Institute of Standards and Technology institute — were able to measure an effect called time dilation at the smallest scale ever, which they say could ...

In another verification of the validity of Einstein's theory of general relativity scientists have used two finely tuned optical lattice clocks to make new ultra-precise measurements of the time ...

“The chief attraction of the theory lies in its logical completeness,” wrote Albert Einstein after publishing his general theory of relativity in 1915. “If a single one of the conclusions drawn from ...

When black holes collide, the impact radiates into space like the sound of a bell in the form of gravitational waves. But ...

The supermassive black hole at the center of the Milky Way is the most extreme astrophysical object located within a million light-years of Earth. With an estimated four million solar masses, it's the ...
