It is impossible for humans to enter a black hole, and can humans enter a black hole?

This statement is uncertain, but it is still possible, because time and space are relative. We know that when the speed of an object reaches a certain speed, the time in the space-time in which it is located will slow down and the space will shrink, which is what we call one day in the sky and ten years on the earth, and when the speed is closer to the speed of light, it is not impossible for one second in the sky and one billion years on the earth (let alone in the next few years).That is to say, the universe in which it is located will be relatively small and small (of course, it is also a closed space-time region), when it is small to a certain extent, it itself seems to us to be a black hole, so whether we humans can enter the black hole as soon as possible, the key is to create a speed, of course, this speed has to be the speed of the real thing.

Because as far as we can see from now, it seems that only physical particles can have a noticeable effect on space-time. Of course, it is impossible for us humans to withstand such high speeds in real-time space, so this idea can only be realized in virtual space. We can come here and envision:

If humanity can make a major breakthrough in particle acceleration in a few years, it may be possible to create a very wonderful thing in real-time space with the astonishing speed of real particles"Wormholes"(Void space-time) so that we humans are able to do so in this man-made"Time and space are channeled"Take a shortcut into a black hole.

Haha, a few years, my brother, you're kidding. It's okay to show for a few hundred years.

In addition, I would like to correct some of the opinions of the people upstairs that the volume of black holes is actually very small, and the more massive the black hole, the smaller its size, and some super black holes are only the size of a football or a blue ball. What we can observe and judge now about the space with a black hole is only its "suction disk" and "gravitational belt", and the so-called entering the black hole does not mean landing on the surface of the black hole, even if we can resist its strong gravitational pull, such a small place is not enough to gain a foothold. Rather, it means that we pass through the super gravitational zone of the black hole, because the gravitational force of the black hole is huge, so the time and space around it are severely distorted, and we can use this characteristic of the black hole to travel long distances in space or time travel.

To achieve this, it is impossible to have a few masters like Albert Einstein and Stephen Hawking, and after hundreds or thousands of years of painstaking research.

Of course you can, but once you're in, you're no longer you. Instead, it became the simplest thing in the universe - time and space - hehe, what it feels like to enter a black hole, no one knows this. But it's certain that the huge tidal forces there will tear you apart ......

Unlikely, first of all, the closest black hole to the Earth is too far away, and the manned technology out of the solar system is not yet mature. And the pressure on the edge of the black hole is too great, and it will be torn apart before it gets close.

No, the huge gravitational pull of the black hole will stretch people and tear them to pieces. This is true even for even the toughest objects.

If the landlord asks about the next few years, I can say "impossible" very directly

And I thought that in the next few years, we wouldn't even be able to fly out of the solar system, let alone go to a black hole.

Not to mention entering a black hole.

It may be almost zero, and now human beings are only conjectures about everything outside the solar system.

No, the black hole is actually a small ball, because the density is too large, the gravitational force is also very large, and the light cannot break through the gravitational circle of the black hole, so it is black, and if people get a little close to it, they will either be torn to pieces, or they will be pulled into ramen. It is almost impossible for a person to get in alive.

It can't be, if you get in, you will be burned to death, because the black hole is like a bottomless abyss.

It is your destiny to enter a black hole. Of course, when you go in, it's just some elementary particles floating around. Perhaps, this will happen in four billion years.

Black holes are still conjectures, and it is still a question whether they can be proved to exist in recent years; So your question is just a conjecture of conjecture, and it doesn't make sense.

It's not impossible. But we can't wait for that day.

A black hole is a big hole that is very black and very black.

At the current rate of technological development, it is impossible.

You can get in, and he's going to jump you to one end of the hole, but not you, it's your substance, and you don't exist at that time, and everything is the same.

Even if you wear an extremely strong protective suit, you will be torn apart by the powerful tidal force of the black hole and become part of the black hole.

The black hole comes to suck you, and you go in ......

The black cave can be entered now.

Humans can't go into black holes.

The gravitational pull of a black hole is already extremely terrifying, and if you are too close, the gravitational pull on your head and feet will be very different. Different forces mean different accelerations, so your head and feet fall towards the black hole at different speeds, so that your entire body is elongated to be far thinner than a noodle.

Black holes

A black hole is a celestial object that exists in the universe in modern general relativity. The gravitational pull of a black hole is extremely strong, allowing the escape velocity within the event horizon to be greater than the speed of light.

Thus, "a black hole is a celestial body with such a curvature of space-time that no light can escape from its event horizon".

In 1916, the German astronomer Karl Schwarzschild calculated a vacuum solution to Einstein's field equations, which showed that if the actual radius of a static spherically symmetrical star is less than a fixed value, a strange phenomenon will be produced around it, that is, there is an interface - "horizon", once entering this interface, even light cannot escape.

This value is called the Schwarzschild radius, and this "incredible celestial body" was named a "black hole" by the American physicist John Archibald Wheeler. Black holes cannot be directly observed, but their existence and mass can be known indirectly, and their effects on other things can be observed.

At 21:00 Beijing time on April 10, 2019, mankind's first black hole** was unveiled, which is located at the center of a giant elliptical galaxy M87 in the constellation Virgo, 55 million light-years away from the Earth, with a mass about 6.5 billion times that of the Sun.

What kind of existence is inside a black hole?

Traveling through that point in the universe would be a completely unsurvivable journey, where time is meaningless, even the fastest particles can't escape, and everything means you're entering a black hole.

For this trip, you have to make an assumption: you are an observer, not a living being that actually fell into a black hole, which means that gravity and energy will not have any effect on your observations. With this seemingly unrealistic assumption, let's take a look at what the inside of a black hole looks like!

At first, the journey to the black hole will be beautiful. Although it is considered pitch black, space is actually dotted with colorful distant worlds that seem to illuminate everything around you endlessly, except, of course, your destination, a pitch-black ominous sphere: the Black Hole.

This sphere can be thought of as a waterfall of light, and at the edge of the waterfall even light cannot escape, and a line of edge is clearly set off by the distorted light behind it, and this edge line is called the "event horizon". As you accelerate towards the viewport, you pass through a photon layer, where the photons reflected from you begin to orbit the black hole, and after a full rotation, they return to your eyes, meaning that you can see the back of your head right in front of you.

The further you go, the more distorted space will appear behind you, knowing that you are facing away from a window to the universe, and your speed has been accelerated to near the speed of light, but it has only just begun.

We all know that the faster you go, the slower time will go. The closer you get to the black hole, the more time dilation will affect you, and your time will pass so slowly that if you look behind you, you can see everything that will fall into the black hole from now on.

Again, in front of you, objects are subjected to greater time dilation, which means you can see everything that fell into this black hole before you, and you can even see the entire history of this point in the universe at a glance, from the big ** all the way to the distant future.

However, this phase doesn't last long, because you're gradually surrounded by vision, until the last small point of light behind you also blueshifts beyond the ultraviolet spectrum and finally disappears, and then you can't see anything anymore, and that's when things finally start to get really interesting, or life is weird.

Because matter has been stretched and shattered into its basic building blocks, all those atomic properties that gave it texture, shape, structure, and color no longer exist, all quarks and gluons are compressed in positional space and expanded accordingly in momentum space, and all motion points to singularities.

We can't describe what it would be like to be like, because the properties of things we depict only apply to our plane, not to a singularity. It's better to think of a black hole as a space with Planck length in diameter, rather than in a traditional sense.

In the process of falling into the black hole, if your body is not particleized, you will find that your body will be stretched very long, you will not be able to see anything outside the black hole, you will feel that everything around your body wants to be still to you, you will not have feelings.
