What is a black hole?

You have to know how to travel tens of thousands of light-years outside of our solar system. Brave the depths of the great interstellar voids, you’ve been witness to some of the most painful, beautiful, and incredibly powerful events in the universe, from the birth of the new solar-energy systems for the violent death of a massive star’s life. And now, for your swan song, you’re going big, you’re about to go for a swim in the pitch black darkness of a massive black hole and see what’s on the other side of the mysterious event horizon. What do you think of that now. Read on, brave explorer.

Close to the sample,

First, we need to clear up a few definitions. There are a lot of different types of black holes: some are big, some are small, some of them with electric charges, and without it, and some of the fast spins, and others may be more sedentary. For the purposes of the adventure in this particular story, I’m going to stick to the simplest possible scenario: a huge black hole with no electric charge and no spin whatsoever. This is, of course, is certainly not realistic, but it’s still a fun story with a lot of cool physics on the way. We will be able to have a more realistic trip for a visitor, based on the assumption that we survive this hypothetical journey into a black hole, which we don’t).

From a distance, it’s a black hole, it is surprisingly quiet. After all, it’s just a solid object, just like any other solid object. The force of gravity and the force of gravity, and the mass is the mass of a black hole with the mass of, say, the sun’s pull on you is exactly the same as the sun itself. All that’s missing is warmth, and light, and warmth, and radiation. However, if you feel like it’s a job to keep a safe distance, it certainly could be.

So why on earth would you get a job if you were going to continue on?

The black hole itself is a singularity, a point of infinite density. But you can’t see the singularity; rather, it is cloaked by the event horizon, which, as a general rule and it might be wise to consider the “surface” of a black hole. In order to proceed, you need first to pierce that veil.

Beyond the horizon

The event horizon is not a physical barrier. It’s not a membrane or surface. It is simply defined as a certain distance from the singularity, and the distance at which if you fall below that threshold, you can’t get out. You know, not a big deal to me.

This is the distance from the singularity where the gravitational pull is so extreme that nothing, not even light, can escape the black hole’s clutches. If you are below this limit, and decided you had enough of this ‘black hole’ of exploration for the company, then it is a bad thing. As much as you have fired your missiles, would in itself not be further away from the singularity. You’ve been caught. It is doomed.

But it is not. You will need to have a couple of moments in order to enjoy the experience before you meet your inevitable demise, if “enjoy” is the right word. How long does it take to reach the singularity, depends on the mass of the black hole. A small black hole (a few times the mass of our sun is considered “small,” you can’t even blink an eye. A very large one, at least a million times brighter than our sun, and you’ve got a handful of heartbeats to experience this mysterious part of the universe.

But to hit the singularity, you have to. You don’t get a choice. Inside the event horizon, there is nothing that can continue to be used. You have to always be compelled in order to leave their homes. And special offers from all your possible futures.

Out of the black hole’s event horizon, can move in any direction in space, that is, you want to be. Up? On the left? A little bit of both? Neither? The choice is up to you. But regardless of where you do (or don’t) are going to be in the area, you always have to travel into the future. You just can’t escape it.

Inside the event horizon of a black hole, these are common-sense understanding of the break. At one point, the singularity is in the future. You just need to travel in the direction of the singularity. Turn around, turn round, run and round, it doesn’t matter, the singularity is always in front of you. You will have to hit that singularity, in a finite amount of time.

The clock is ticking.

A rendez-vous with eternity

If you are in the in the direction of the singularity, and you’re not cloaked in darkness. In the light of the surrounding universe, and fell and continues to fall behind you. Due to the extreme force of gravity is slightly shifted to higher frequencies, and due to the time dilation of the out-of-universe developments, but it is still there.

That’s not to say that it’s not funny.

Because of the mass of the black hole is concentrated in an infinitely small point, the differences in gravity extreme. You’re stretched head to toe, in an aptly-named process is known as spaghettification. And, what’s more, you are pressed up along my stomach. This pinch has been active in the rays of light to you as well, and the focus of the incident light, a light band across the waist.

The appearance of the singularity, that is, the grotesque, and distorted as well. It’s pitch black — you can’t see it, because it is in the long-term future, as well as the long-term future, and you don’t know what it’s like until you’re there. However, instead of a small dot, massive gravity and the differences stretch out to swallow the majority of your vision for the future.

As you approach the singularity, it seems as if you have the right to land on the surface of a vast, featureless, empty, and black planet.

When death stretches out of the horizon to the horizon, and then you’ve got it made.
