For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth ...

Scientists observed a spinning black hole dragging space and time as it tore apart a star, confirming a key prediction of Einstein’s theory of relativity ...

For the first time, astronomers have captured the brilliance of a superluminous supernova via gravitational lensing.

Astronomers have observed a star wobbling in its orbit around a ravenous supermassive black hole that is ripping it apart and ...

Astronomers observed a star wobbling around a spinning black hole, revealing rare evidence of Einstein’s frame-dragging ...

Even worse, the orbit of Mars is elliptical (think of a slight oval rather than a perfect circle), which means that sometimes ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to be folded neatly into the quantum rules that govern the rest of nature. Now a convergence of bold ...

Scientists detect a 20-day wobble from a star-shredding black hole, confirming spacetime twisting predicted by Einstein.

If you're going to Mars you'd best take along a jar of anti-aging cream because while you're there you're going to age faster ...

Albert Einstein and Carl Sagan both knew a lot about science. Sagan said, “We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything ...

The idea that we might be living in a simulated reality has worried us for centuries. Now physicists have found some ...

Summary: Time doesn’t flow uniformly across the solar system, and new research reveals just how differently it unfolds on Mars compared with Earth. By tracing subtle gravitational and orbital ...
