AI can make mistakes

New "black hole stars" have been discovered, potentially solving the mystery of "little red dots" seen by the JWST in the early universe. These objects are the size of our solar system but emit immense energy. Astronomers also found three black holes in a young galaxy and observed two black holes on the verge of merging. Black holes are extremely dense objects from which nothing, not even light, can escape, defined by their event horizon.

Black hole - Wikipedia

Ablackholeis an astronomical body so compact that its gravity prevents anything, including light, from escaping. Albert Einstein 's theory of general relativity, which describes gravitation as the curvature of spacetime, predicts that any sufficiently compact mass will form ablackhole. [4] The boundary of no escape is called the event horizon. In general relativity, crossing ablackhole...

What Are Black Holes? - NASA

Ablackholeis an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. Ablackhole's"surface," called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos. Matter and radiation fall in, but they can't get out. Two main classes ofblackholeshave ...
