The Black Holes

Black holes are massive astronomic objects where gravity is so strong, that any particle, even the light, can escape from it. Black holes are the most fascinating and misterious objects in the universe, they are formed from dead stars, that when it run out of fuel, its core collapse and that trigger a supernova explosion.

Black holes are invisible, its core its completely black, because light particles can't escape from it, so it can't reflect light and isn't visible. But black holes don't suck thing, it only absorb those thing that get in it. The light can curve and form a light ring around it.

There are million of black holes in our galaxy, but they aren't as big as the supermassive black holes. The supermassive black holes are millions times bigger than the Sun, it's know that there is a supermassive black hole in almost every galaxy, included ours.

Although black holes where at first speculative solutions for Einstein equations of the Theory of Relativity, in 2019 the Event Horizon Telescope took the first photo of a black hole, it is at 55 million light years away from Earth. This discovery is a great event
