An artist's visualization of the star S0-2 as it passes by the supermassive black hole at the galactic center. As the star gets closer to the supermassive black hole, it experiences a gravitational ...

Testing Einstein: conceptual image showing S0-2 (the blue and green object) as it made its closest approach to the supermassive black hole at the centre of the Milky Way. The huge gravitational field ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

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 ...

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

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 ...

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 ...

PARIS, FRANCE - NOVEMBER 23: Specialist in the Books and Manuscript department at Christie's, Vincent Belloy poses with the Einstein-Besso manuscript written jointly by Albert Einstein and Michele ...

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 ...
