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 ...

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 ...

Albert Einstein had described the special theory of relativity in 1905. The result of Einstein's thinking about light, this theory introduced brand-new ideas to science. It opened up an entire field ...
