Scientists announced Tuesday that the telescope had given scientists the longest and most detailed glimpse thus far of the supermassive black hole at the center of our Milky Way galaxy.

The team behind new research on the topic suggests that measuring whether gravitational waves from black hole mergers are right- or left-handed can tell us if the Cosmological Principle — an ...

Back in 1971, a couple of British astronomers predicted the existence of a black hole at the center of our galaxy. And in 1974, other astronomers found it, naming it Sagittarius A*. Since then, ...

There’s a pretty hot party raging in the black hole at the center of our galaxy. Using new observations from NASA’s James Webb Space Telescope (JWST), a team of astrophysicists found that the ...

Illustration: NASA, ESA, CSA, Ralf Crawford (STScI) The black hole at the center of our galaxy is experiencing a flurry of flares, ranging from flickers to brilliant eruptions, according to a team ...

For example, any primordial black hole smaller than 10 12 kg would have already evaporated thanks to Hawking radiation. Anything larger than 10 20 kg would gravitationally lens stars in the Milky Way.

In one framework, gravity operates within the three-dimensional geometry of the black hole. In contrast, particle physics is confined to the two-dimensional surface, resembling a flat disk.

Exotic matter is largely theoretical and has not been observed in nature, but is used in models to explore concepts such as wormholes, faster-than-light travel and the resolution of black hole ...
