Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

Could the Universe have been born inside a black hole? This question, raised by a team of scientists, challenges the Big Bang ...

Black hole quantum effects are usually thought to be too small to have any observable signatures. This is indeed the case for ...

Alternative black hole models incorporating quantum effects suggest singularities may not be necessary, proposing regular black holes and mimickers without central singularities.

"Frame dragging is an effect present around all spinning black holes." The "wobbling" remains of a star that suffered a grisly death at the maw of a supermassive black hole has helped reveal the ...

The idea behind the Zel’dovich effect came from an unusual place. In 1969, British physicist and mathematician Roger Penrose suggested that energy could be extracted from black holes by lowering ...

Real-Life Black Hole Sounds Like A Mass Effect Reaper ... “Since 2003, the black hole at the center of the Perseus galaxy cluster has been associated with sound,” NASA wrote in a press release.

Without accounting for nonlinear effects, physicists may be wrong about the size and other properties of the black holes they detect—of which there have been many with LIGO over the past few years.

By looking at radio waves and X-ray emissions, a team of physicists has found the supermassive black hole Sagittarius A* to be spinning— and altering space-time around it.

Around black holes, massive objects whose gravitational pull dwarves that of any planet, these relativistic effects become far more pronounced. To understand why, imagine falling toward a black hole.

The black-hole binary in this study, colloquially known as GW200129 (named after the date it was observed, January 29, 2020), precesses several times every second -- an effect 10 billion times ...

The James Webb Space Telescope has shown that the Milky Way’s black hole is constantly blazing with light, releasing long flares as well as short flashes every day.
