Journey into a black hole

As you approach, you feel the hole pulling harder on your feet than on your head, because gravity is more intense the closer we are to the massive object . Added to this peculiar sensation, he feels as if he were compressed laterally with a straitjacket, since all the points of his body are directed in unison to the center of the hole. This combination of stretching and compression is increasing in such a way that it shreds our beloved director turning him, literally, into a long noodle.

In a few seconds its remains cross the border that separates the universe from the interior of the black hole: it is the event horizon or limit of no-return , where the escape velocity coincides with that of light. Once past it is impossible to leave .

Meanwhile, the rest of the newsroom -which observes from the tranquility that distance gives- will see that the director’s trip is abnormal. As you approach the event horizon, your movements slow down and your wristwatch slows down, until it comes to a complete stop at the event horizon: the newsroom will have to wait an infinite amount of time to see you cross that surface.

Seen from the outside, time freezes on the surface of the black hole, although for the poor director of MUY the journey has lasted a few seconds.

A black hole of ten solar masses causes an acceleration in the event horizon fifteen million times greater than that of the Earth. As the human body can only withstand about ten times the acceleration of gravity on the surface of the Earth, our protagonist would have ceased to exist 3,000 kilometers from the hole.
