Black holes challenge science so much that even some scientists doubt their existence.
Despite black holes' terrible reputation, we've never actually seen them. We know that black holes exist all over the universe, in every corner of our galaxy. However, that doesn't mean they are easy to find.
You can almost imagine how difficult it would be to try to find a freely floating black hole in the fabric of space time with a black background. This situation is also paradoxical because scientists believe that the birth of black holes was some of the brightest explosions in the universe.
In fact, black holes rise from the corpses of stars that have exploded many times larger than our Sun. The star that burns for ten million years collapses into itself within seconds, forming a black hole. With this collapse, the outer region of the star hits the core, triggering a huge explosion, a supernova... We see this explosion, but we cannot see the rest. A dead core where the immense mass of a star thousands of times larger than the sun is compressed into an infinitesimal space. From this dead core, a high mass black hole is born. The gravitational flow around the black hole is so strong that nothing can escape from it. Not even light..
