Web18 de jan. de 2024 · Black holes have no such mathematical-physical limitations. As Insider explains, the supermassive black hole at the center of our astronomical neighbor, the Andromeda galaxy, has a diameter as big as Jupiter's revolution around our sun, 516 million miles. Its mass isn't a mere 4 million times that of the sun, like Sagittarius A at the center … WebBlack holes are some of the most fascinating and mind-bending objects in the cosmos. The very thing that characterizes a black hole also makes it hard to study: its intense gravity. All the mass in a black hole is concentrated in a tiny region, surrounded by a boundary called the “event horizon”. Nothing that crosses that boundary can return to the outside …
