To simplify calculations, the study uses a planar black hole model (a flat, 2D version) instead of the usual spherical one. Researchers believe their findings may also apply to regular spherical ...

In 2018, astronomers at MIT and elsewhere observed that the black hole's corona—a cloud of whirling, white-hot plasma—suddenly disappeared, before reassembling months later.

Further baffling astronomers, radio data from February, April and May 2024 reveals what appear to be jets of ionized gas, or plasma, extending from either side of the black hole – a rarity for ...

Astronomers found a black hole acting unusually in 2018. Now, it's shooting out radiation at increasing speeds, which is an unprecedented behavior.

A white hole is a black hole in reverse. Instead of absorbing all matter, energy and light outside of it as a black hole does, a white hole emits matter, energy and light, and cannot be entered from ...

White holes are theoretical cosmic regions that are opposite to black holes. Just as nothing can escape a black hole, nothing can enter a white hole.

The device, reported in Advanced Photonics, functions as an optical black hole or optical white hole, and rests on a principle known as "coherent perfect absorption" of light waves. Dependent on ...

One final interpretation of white holes to end the discussion on. “You can think of the Big Bang as the ultimate white hole,” said astrophysicist Ezequiel Treister in a 2011 NASA chat.

The black hole in question is 1ES 1927+654, located around 270 million light-years from Earth, with a mass around 1.4 billion times that of the sun. 1ES 1927+654 first announced its weirdness to ...

A white dwarf star apparently whips around its companion black hole once every 28 minutes, a new study suggests. That means the duo are likely separated by just 2.5 Earth-moon distances — the ...
