Your brain has taken millions of years to get here, and it’s ready for this gaze into the darkness. So let’s get started
Welcome to the place of no return: a region in space where the gravitational pull is so strong, not even light can escape it. This is a black hole.
The edge of a black hole, its event horizon, is the point of no return. At the event horizon, light is drawn in to a black hole, never to escape. And nothing is faster than light.Will gravity rip you apart and crush you into the black hole’s core? Or will a firewall of energy sizzle you into oblivion? Could some essence of you ever emerge from a black hole? The question of how you would die inside a black hole is one of the biggest debates in physics.
The notes stayed in the galaxy and never reached us, but we couldn’t have heard them anyway. The lowest note the human ear can detect has an oscillation period of one-twentieth of a second. This B flat’s period was 10 million years. Theoretically, if you shrank any mass down into a certain amount of space, it could become a black hole. Our planet would be one if you tried to cram Earth into a pea.On March 28, 2011, astronomers detected a long gamma ray burst coming from the center of a galaxy 4 billion light-years away. This was the first time humans observed what might have been a dormant black hole eating a star.
And until now, it has never been done. So far, scientists have detected black holes only indirectly, by their signatures, such as a gamma ray burst, supernova or, perhaps, an object on the brink of a black hole’s event horizon. Typically, if tremendous energy is emanating from a massive core at the center of a galaxy, the core is probably a black hole.
Scientists had smaller ones in mind. In theory, the search for the smallest particles in the universe might kick up mini black holes in the collider’s underground tubes, enabling researchers to observe general relativity and quantum mechanics in action, and perhaps open the door to solving the firewall paradox.
