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

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

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

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 ...

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.

Scientists Built a ‘Toy Model’ of a Black Hole Bomb—and Brought a 50-Year-Old Theory to Life. ... Electrical waves spin off in random ways until they compound and create a runaway effect.

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.
