There are few scientific concepts that are as famous as Albert Einstein's theory of general relativity, but even the iconic theory isn't set in stone. Einstein's theory of general relativity states ...

Albert Einstein’s mind reinvented space and time, foretelling a universe so bizarre and grand that it has challenged the limits of human imagination. An idea born in a Swiss patent office that evolved ...

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 ...

Planets that orbit white dwarf stars should be too hot to host alien life, theories suggest. But a new study accounting for ...

Once again, scientists have shown that Albert Einstein's theory of special relativity is right — this time, thanks to a particle detector buried deep beneath Antarctica. Scientists from the 1-gigaton ...

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 ...

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 ...

More than a century has passed since Albert Einstein gave us general relativity, and scientists are still testing the mind-bending theory. In the latest test, an international team of astronomers used ...

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 ...

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 ...

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 ...
