Scientists speculated about the existence of black holes over a century ago. Nowadays it is commonly accepted that every galaxy in the universe has a black hole at its centre. And what is a black hole? A black hole is a region in the universe with gargantuan mass and high gravitational pull. The mass and gravity of such area exceed several times that of a common star like the Sun. Due its gravity, nothing can escape from a black hole, even the light rays, once they are caught inside by its borderline, called the event horizon. Since no light rays can come out of it, black holes always appear blank. They are invisible black areas in the universe which can be detected only by its interaction with nearby space, time and other matter in the vicinity.

Imagine a black hole as something like a water-well on our earth. Assume that, the well has some sort of magnetic capacity which will attract everything that goes above. If you try to peep into it, you are definitely pulled in, even if you are standing a bit away from its edge. And you can never ever escape. Whatever kinds of rescue devices are brought to this place, and whichever human of Supermanic abilities offered help, the recovery is impossible. Any such retrieval measures is suicidal; they will be killing themselves. The fate of something that goes into the well is uncertain, as nobody has so far returned, once went into the well…
…that was how a black hole appeared in my last night’s dream!
In the dream, I and my friend wished to go to someplace, and we had to go through the dreadful place where this well-like black hole existed. My friend was in haste, so he left first, and I agreed to go after him. I never imagined that my friend would have shown that condemnable courage to offer a furtive look into the black hole. But, fatal things happen sans any procrastination, though happiness always comes delayed.
That was shocking! I never guessed my friend would have even dared to go close to the well. How could he act so stupidly? So what I do next? I have another friend, a trusted one. I can rely on him, though I am unsure about his capabilities. We both decided to go to the black hole for a sneaky inspection. We found the black hole has a circular sidewall apart from the concrete bar overhead supported on two vertical columns.
Though we both were hesitant a bit to approach the black hole, we decided to offer a cautious glance, doing away with our fear. We went close and tried to look into the well, by clutching firmly on the sidewalls. Everything is dark inside the wall. Darkness gushes upwards in a continuous manner from the depth of the well and comes to a halt at the edges of the sidewalls. Is there something attracting us smoothly? We leant a little more towards the mouth of the water well. And yeah, that is true! There is a sort of magnetic pull coming from the depth of the chasm. We withdrew ourselves back. So, it is true! Our friend has done what he shouldn’t have attempted.
A problem! My friend couldn’t have gone inside by simply looking into it. Because as we experienced, the magnetic attraction was not so great that it did not pull us while standing close to it. My reliable friend came with a solution. As we are close to the black hole, we could have controlled the time. Yes, the time! According to Physics, the time in the surroundings of a black hole runs slower than on earth due to gravity. By the way, do you remember Interstellar (2014), the film by Christopher Nolan? We can’t be sure if my friend is completely lost forever in space-time, or whether he is experiencing the pleasant state of timelessness in the web of the black hole.
My reliable friend tried to do something that I couldn’t have done. He manipulated the time, and we both went back to a time phase in the past. We found ourselves exactly a few hours back from the present. We saw my former friend standing at the tip of the black hole. What is he doing there?
We saw him climbing on a nearby tree, and jumping down in such a way that he would not have fallen directly into the well. I understood! He is testing the magnetic power of the well. Would he be pulled in by the black hole, if he let him fall from the tree above, by narrowly missing the mouth of the well? That’s what he is testing. Having such an idiotic curiosity is surely poisonous. We saw him falling straightly into the black hole while jumping down from the tree slightly allowing his body parts to be at the magnetic field of the black hole that extends infinitely upwards. Having witnessed the mishap, my reliable friend brought both of us back to the present time.
After waking up from the dream, I soon recollected that all the history of the entire universe is recorded in a mixed language of English and Mathematics on the inner walls of the well. The inner walls were imprinted by amber coloured digital figures all the way from the top, and that writings extended infinitesimally towards a bottom that existed somewhere in the far ends of the universe.
It seems that reading hypothetical scenarios in Quora makes me watch such weird dreams nowadays.
