Black holes still remain a mystery to scientists, challenging the postulates of modern physics. We hardly understand the principle of their existence and practically do not understand what they really are and what they do. And it’s impossible to find out.
At least with the current level of technology that humanity possesses. The only thing left for us is to observe them and make assumptions about what they are capable of. One of the most popular questions about black holes is this: what will you expect if you fall into a black hole? Let's look at 10 of the most creepy theories that answer this question.
The information paradox of black holes has baffled scientists for decades. This mystery has spawned countless controversies about what actually happens once you fall into a black hole. To make it easier to understand this paradox, let's look at an example from a hypothetical Lucy.
You fly yourself with Lucy into a black hole, and at the last second she decides not to get there and is now watching how you are sucked in there. Lucy sees that as you approach the black hole, your body slowly begins to stretch and eventually splits into atoms. Lucy thinks that you are lost and is grateful to fate that she did not listen to you and did not go after you.
But wait. This is not how the story ends. You actually remain alive and continue to delve into the infinity of the black hole. What will happen to you next is not the essence of our question. The most interesting thing is that you survived, even though Lucy saw you die.
This is the information paradox of a black hole. This is no illusion, and Lucy has not lost her mind. This is what it really is. The laws of physics tell us that you can be both dead outside a black hole and alive while in it. Some scientists theorize that this is not a paradox at all, since you simply cannot observe two realities at the same time.
Others point to cloning (the possibility that another you exist in a different reality) as a possible solution to this paradox, even though it challenges the laws of quantum mechanics about the process of storing information.
There is no definite answer for solving this paradox (yet). Perhaps in thousands of years, humanity will be able to figure out what is really going on. However, it is already known for sure that Lucy is no longer worth taking with you on trips.
There is an assumption that as soon as you get into the event horizon of a black hole, you will begin to experience powerful stretching caused by a large tidal force in a very strong inhomogeneous gravitational field. As soon as you start falling into a black hole, forces begin to act on your body, which will eventually tear you into small pieces (or rather even particles).
Moreover, if you fall into a black hole first with your head, it will move so far away from your body that you will begin to look like spaghetti. The bottom line is the difference in acceleration due to gravity that will affect your head and legs. It will be so colossal that you will stretch out like spaghetti or noodles, if you like. Hence the name - spaghettification.
Distortion of light, space and time
The first thing anyone will notice before entering the event horizon of a black hole is how different light, space and time will become. As soon as you get inside, the laws of physics (those that are known to us) will cease to exist for you, and completely different forces will come into force.
The infinite level of gravity that the singularity in the center of the black hole produces is capable of warping space, turning back time and changing light beyond recognition. Because of this, your perception of what is happening now will be completely different from what happened before the moment you got into the event horizon. Of course, this will last exactly until the moment when you are completely absorbed by the endless darkness and are no longer able to perceive anything at all.
The greatest physicists who lived on our planet, such as Einstein and Hawking, at one time theorized that time travel to the future would be possible through the use of the internal laws of black holes. As mentioned earlier, the usual laws of physics inside a black hole cease to operate and completely different ones take the main role. One of the things that distinguishes black holes from our world is how time flows in them.
The gravity inside a black hole is so powerful that it can warp time. Taking this into account, it can be assumed that the warping of time opens up the possibility of travel in it.
Therefore, if we learn to use such striking differences between space inside and outside the event horizon, then, it is quite possible, due to the gravitational time dilation, we can go to the future, where you will still remain young, while your friends will already grow old.
Of course, do not forget that we have not yet come up with anything other than a way to travel through black holes, we do not even know how to get to them and, more importantly, survive all this.
Nothing will happen to you
If one day we have a choice over which black hole to travel through, then most likely we should choose some kind of supermassive black hole or Kerr black hole.
If we can ever get to a black hole located at the center of our galaxy, which is about 25,000 light years away and about 4.3 million times more massive than our Sun, then perhaps we can be completely safe for our health. go through it.
The concept of this idea is that the gravitational forces of the hole, acting on whoever wants to get into it, will be quite insignificant due to the fact that the event horizon is located much further from the center of the black hole. Thus, you can stay alive inside the event horizon and die only from hunger and dehydration, and, possibly, from the fact that you will finally fall into the singularity. Here you can place bets on what happens first, because there is no more precise answer yet.
Moreover, it is theoretically possible to stay alive and live the rest of your life inside the Kerr black hole, which is a completely unique type of black holes, the theory of which was first proposed in 1963 by the New Zealand mathematician and astrophysicist Roy Kerr.
Then he suggested that if black holes are formed from dying binary neutron stars, then it will be possible to get inside such a black hole completely safe and sound, since the centrifugal force will prevent the emergence of a singularity in its center.
The absence of a singularity in the center of the black hole, in turn, means that you will not need to fear infinite gravitational forces and you can survive.
According to Einstein, until the very end, you will not understand what is happening
Einstein suggested that if a certain level of free fall is achieved, then it is possible to cancel the influence (or rather the perception) of the forces of gravity. This means that if a person in free fall ceases to feel his own weight, any thing that is thrown into a black hole with him will not appear to be falling. Rather, it will seem like it will float.
Einstein developed this idea and, on its basis, deduced the world-famous theory of general relativity, his perhaps the most successful idea. And perhaps it will be the happiest thought for you if you fall into a black hole. Even if you fall into God knows what, you still won't be able to understand what you are falling, until you fall into the singularity.
However, if at this moment someone can watch you from the side, then they will definitely see that you are falling. All of this is related to perception. Whatever surrounds you, it will fall relative to you (and as a result you will not be able to understand that you are falling), while for all those who will follow you, it will not be so.
It is known that black holes ultimately consume absolutely everything that falls into their event horizon. Even the light cannot escape a tragic fate. Less well known is what happens to all these doomed particles further. According to one theory, anything that enters a black hole from one end is ejected outward from the other end. And this second end is the so-called white hole.
Of course, no one has ever seen any white holes (and black holes, too, frankly. We know about their existence only due to their powerful gravitational effect), so no one can say with certainty whether they are really white. However, the reason they are called that is because white holes are the exact opposite of what black holes are.
Instead of absorbing everything around them, on the contrary, they spit out everything that is inside them. And as in the case of a black hole, from which it will not be possible to escape, if you get into its event horizon, so with a white hole everything is the same. Just the opposite: you cannot get into it.
In short: the white hole spits out everything that was absorbed by the black hole into an alternative universe. This theory has to some extent led physicists to wonder about the possibility that white holes are the basis for creating our universe as we know it. And if you ever get into a black hole and somehow survive and can get out from the other side through a white hole in an alternative universe, then you will never be able to return back to our universe.
You will follow the history of the development of the Universe
As mentioned earlier, there is a possibility of black holes without a singularity at their center. Instead, there will be a so-called wormhole in the center. If we find a way to travel through a wormhole, then, most likely, we will become a witness to the history of the evolution of the universe, which can be observed all the way to whatever is at the other end of the wormhole. It will look as if someone has launched a video with the history of the Universe in infinitely fast rewind.
Unfortunately, this story will still have a bad ending. The faster the picture moves, the faster you will get closer to your death. The light will become more and more blue-shifted and charged until you are completely roasted alive by its radiation.
Travel to a parallel universe
If one day you fall into a black hole, whether deliberately or accidentally, the first thing to do is to try to look around. Maybe you can find a way out this way, who knows. Even if it turns out that you will not be able to return to the Universe where you came from, then being in a parallel Universe may not be such a bad end to your journey.
Physicists theorize that once you reach the singularity of a black hole, it can serve as a kind of bridge for you between this and an alternative reality, or the so-called "parallel universe". What happens in this new universe remains a mystery and a field for our imagination.
Some theories even suggest that there are an infinite number of alternative universes, each with an equal number of completely different "you".
Ever thought about the choices you've made in your life? What would happen if you got a job not for this, but for that job, met that girl or guy, instead of sitting at the computer every day? Would you be richer or poorer if you hadn’t done or done what you were once asked to do? So, in an alternate universe, you will have a chance to find out.
You will become part of the universe
Hawking once suggested that certain particles entering a black hole undergo a kind of filtering process into positively charged and negatively charged ones. These particles are very slowly absorbed by the black hole. When immersed in it, negatively charged particles lose their mass.
Positively charged particles have enough energy to stay outside the black hole as radiation.
According to Hawking, black holes are slowly but surely losing their mass and getting hotter. They eventually explode and scatter their contents, called Hawking radiation, back into the universe. This, at least in theory, means that you can become part of the universe, like a Phoenix reborn from atomic ash.
Bonus: you just … die
Sometimes we love to ignore the most obvious and dire consequences of an event, being blinded by the likelihood of more joyful coincidences.
As sadistic as it may sound, the most likely result of your falling into a black hole will be that even before you can simply understand your presence inside it, you will not even have ashes left of you. You won't even have time to understand that you've witnessed what physicists talk about as the key to understanding the mysteries of the universe.
