We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

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 ...

Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold new line of research now argues that gravity is not fundamental at all, ...

The first image of a black hole, captured in 2019, has revealed more support for Albert Einstein's theory of general relativity. The new finding has suggested his theory is now 500 times harder to ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

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 ...

A study by physicists affiliated with the Foundational Questions Institute (FQxI) found that time ...

Decades in the making, a space probe that delves into Albert Einstein's general theory of gravitation remains grounded on Earth, caught in its own space-time continuum of technical snags, costly ...

General Relativity, Einstein’s seminal theory of gravitation, remains a pillar of modern physics by describing gravity as the curvature of spacetime. Nonetheless, persistent questions—ranging from the ...
