To the black hole and back

(ORDO NEWS) — A black hole is a region of space-time, the gravitational attraction of which is so strong that even objects moving at the speed of light, including quanta of light itself, cannot leave it.

Every galaxy has a black hole, and it is the center of this galaxy, the Milky Way also has a black hole, it is called Sagittarius A.

Black holes are very diverse – their mass can vary from a few solar masses to billions of solar masses.

When a star runs out of fuel for thermonuclear fusion, if the mass of the star is at least 2.5 times that of the sun, it turns into a black hole.

Each star has its own event horizon – the border crossing which no object can get out of it.

For Sagittarius A, the radius of the event horizon is not even the radius of the orbit of Mercury, while for the largest open Black Hole – NGC 3842, it can be several radii of the orbit of Pluto.

Sooner or later, the technologies of mankind will reach such a mark that their devices will be able to travel to Black Holes and directly study them.

In this article, we will discuss how the journey of a starship to the Black Hole at the center of the Milky Way will be.

For starters, the device may have difficulty approaching the Black Hole, not in the sense that it takes a very long time to fly to it, but that, according to the Theory of Relativity, Black Holes noticeably bend not only time, but also Space.

Thus, the space near the Black Hole will be larger than the space farther away, thus the starship will be pushed out of orbit, but in fact, strange as it sounds, the starship will stand still. One of the ideas of instantaneous travel in space is based on the same principle.

The same process is observed with pressure on the ball at one point – the matter of the ball is bent, while taking with it the point drawn on it.

However, it is possible to make adjustments with the motor, much like walking up a moving staircase in the opposite direction.

Due to the same curvature of space-time, the spaceship will stretch to several kilometers, if not tens of kilometers.

It is worth mentioning that time will go slower there than outside the Black Hole. Thus, if the device is controlled remotely, you will have to constantly correct its time.

And if he is inhabited, then if he manages to get out of orbit, then when they return, they will become younger than their peers. It will seem to them that two months have passed, but in fact more have passed.

There will also be big communication problems.

The fact is that the gravity of the Black Hole is enough to bend the radio signal coming from the starship to the station observing it, and it will not be possible to observe it, because the light will also be unpredictably bent.

This also eliminates the option of remote control, so that astronauts and scientists will have to go at their own peril and risk with this starship to the Black Hole. Orientation and use of the navigation system will also fail, and the researchers will not be able to understand where they are.

However, if they start to go out of orbit, then this can be found out by turning off artificial gravity and checking if objects fall to the floor, if so, then they fell out of orbit and before it’s too late, you need to turn on the engines and go back to the previous orbit.

Moreover, in order for the device to stay in orbit, near-light speed is required, at which objects will again be bent, but any curvature of the crew will not affect the crew, although they will be noticeable.

Even halfway to the center of our galaxy, the Sun has to develop a speed of 500 kilometers per second just to stay in orbit, and no one knows if it keeps in its orbit, or falls a little into the Black Hole.

All these facts make it incredibly difficult to travel and explore black holes.
