A prediction made by Albert Einstein in his theory of general relativity has come true as astrophysicists have detected light coming from behind a black hole. A team of scientists made the analysis ...

A century after Albert Einstein sketched out his radical picture of gravity, astronomers have now watched a black hole ...

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 ...

For the first time, astronomers have directly observed a spinning black hole bending space and time, as predicted in Albert ...

Finally, scientists have their finger on the pulse. Spinning dead stars, known as pulsars, blast powerful beams of radio waves into space. As a pulsar spins, its beams sweep past Earth, producing a ...

E = mc^2. General relativity. The photoelectric effect. Brownian motion. Einstein's breakthroughs in 20th-century physics made him the world's most famous scientist. And the recognition is ...

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 ...

Everyone knows Albert Einstein was a genius, but can you explain what he’s famous for? Arguably his foremost theory, his general theory of relativity, turns 100 years old this week. It was actually ...

The Princeton that Albert Einstein knew in 1933 was sharply divided by the color line; a long-established border—marked by ...

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 ...

Small modeling errors may accumulate faster than previously expected when physicists combine multiple gravitational wave events (such as colliding black holes) to test Albert Einstein's theory of ...
