In the most comprehensive test of general relativity near the monstrous black hole at the center of our galaxy, researchers report that Einstein's theory of general relativity holds up, at least for ...

Einstein’s Theory of General Relativity is currently our best approximation of how the universe ticks. But there are holes.

Like Max Planck, Albert Einstein first studied mathematics because he was told that everything interesting in physics had already been discovered. But in 1905, Einstein, a young cleark at the Swiss ...

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 ...

July 26 (UPI) --It's been more than a century since Albert Einstein published his theory of relativity. And while new research shows that it remains intact, they also say new questions have arisen. A ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the ...

Since 1915 when Albert Einstein published his theory of general relativity, scientists have worked on testing its limits, and with the results of this 16-year test, it still holds up. Professor ...

A star known as S0-2 (the blue and green object in this artist’s rendering) made its closest approach to the supermassive black hole at the center of the Milky Way in 2018. (Nicole Fuller / National ...

A 54-page document handwritten in 1913-1914 by Albert Einstein and Swiss engineer Michele Besso, sold in Paris earlier today for €11.6 million (US$13.0 million). It’s not the most valuable document ...

Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold ...
