In the heirarchy of black holes, intermediate mass black holes (IMBH) lie in between stellar mass black holes and supermassive black holes. But the problem is that we've never found one. There have been hints, but nothing conclusive.…

The JWST has shown us some strange things about supermassive black holes (SMBH) in the early Universe. Many of them are far more massive than we think they should be.…

When a massive star dies, it can leave behind a black hole. That much has been understood for decades. But the most monstrous black holes in the universe, the heavyweights detected by the faint ripples they send through the fabric of space and time aren't…

Black holes don't live forever, but they might live long enough to look like white holes

Black holes live forever, at least according to general relativity. Once material crosses a black hole's event horizon, it is trapped forever, until the last day of cosmic time. But we know that isn't true. General relativity is a classical model.…

The Universe’s biggest black holes may not be born giants after all. Scientists analyzing gravitational-wave signals from dozens of black hole collisions found evidence that the heaviest black holes are likely “cosmic recyclers” — formed through repeated…

Black holes evaporate through Hawking radiation, meaning their days are numbered. But a new study finds they could enter a metastable stage where they look similar to white holes.
