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 ...

For more than a century, Einstein’s relativity has set a hard speed limit for the universe, with light as the ultimate ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to be folded neatly into the quantum rules that govern the rest of nature. Now a convergence of bold ...

Einstein's theory of general relativity may be over 100 years old, but a 16-year-long investigation of extreme stars has shown that it is still the best description of gravity we have. An ...

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 study of relativistic effects in gravitational fields remains at the forefront of physics research, refining our comprehension of space‐time and its intricate interplay with matter. Notably, ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...
