Here's an example from public sources.
The Human Brain Project (HBP) is a large human brain research project founded in 2013 in Geneva, Switzerland. The project involves hundreds of scientists from 26 countries and 135 partner institutions. The HBP project is unprecedented in its scale and the largest in the history of human brain research, with a budget of 1.6 billion dollars.
Similar projects have been launched in the US (BRAIN Initiative), China (China Brain Project) and Japan (Brain/MINDS).
Scientists have been able to transfer human consciousness (though not completely) into a computer. Now researchers are trying to upload human consciousness not only into a computer, but also into another human organism.
There is a lot of information about such works, conducted in the USSR, already in open sources. In her interviews and partially in her book "Brain Magic and Labyrinths of Life" academician Natalya Bekhtereva tells about such works carried out in secret research institutes in the USSR. Back in the days of the Soviet Union, being a secret communicator, I myself knew about such works directly from telegrams marked "top secret". And from negotiations – even more "frank" information. Here I should specify that I heard similar and more incredible information in negotiations, of course, in a closed network, not from the military, but directly from the employees of secret research institutes, because I was at the facility where they were testing new types of weapons. And the scientists talked about everything they were working on. So, according to them, this technology in the USSR was developed by a secret academician, who died after an unauthorized test on himself. There was, of course, and another version, which was put forward by colleagues: the academician transferred his consciousness into a younger employee, and made his body dead. A brilliant alibi.
Chapter 5. Tangled Couples
Now let's get to the fact that the reality of what we are going to speculate about is taken on faith. We do, after all, believe in the atom, god, dark matter, the human soul, and many such things. Or at least partially in any of these and similar things.
So believe that there is everything in infinity. And do not forget my main postulate: if you said "not everything", it means that you have presented a minuscule part of this eternity. Therefore I declare that these parallel worlds really exist, moreover – they are an exact copy of ours. I will cite quantum teleportation as proof. Since not all my dear readers understand subtleties of this process, I will make detailed explanations.
Let me explain how it can be. In physics, quantum teleportation is a very real thing. What is it? It is a transfer of quantum state of an electron, i.e. a tiny particle, of which, however, our world and we ourselves consist. So, it is a transfer of particle states over a distance by means of a coupled (or entangled) pair separated in space.
Quantum entanglement is a phenomenon in which the states of two (or more) particles appear to be interdependent. For example, it is possible to receive a pair of particles which are in an entangled state, i.e. connected with each other as if by kinship ties, and then if at measurement of a regular circle, let's say, of the first particle the helicity turns out to be positive, then the helicity of the second particle will always be negative… and vice versa. Such interdependence is always preserved even if these objects are separated in space beyond any known interactions. So, logically, they should have no connection. But a change in the parameter of one particle leads to an instantaneous change in the state of another. It's a miracle. And this miracle is possible because the process occurs instantaneously… not just above the speed of light, but instantaneously. And here I can prove that this is not some kind of miracle, but quite a natural phenomenon. According to the laws of physics, as we know, nothing can be transferred from one place to another at a speed greater than the speed of light. Accordingly, we know nothing about anything that moves above the speed of light. Quantum teleportation does not transfer energy or matter over distance. The fantastic notion of teleportation comes from a specific interpretation of the experiment: the original state of the particle collapses after all that has happened, as if it were to appear elsewhere. That is, the state was not copied, but transferred from one place to another. Well, now you will say that this is nonsense, because in fact both energy and information are transferred. Information, I think, for sure. Because the state of one particle is transferred to another particle. All right. Let's do this – you will believe me without these scientific details, because the fact of influence is there, but there is no scientific substantiation yet.
Let's return to our thought experiment. In order to realize such an experiment, first of all, we need to invent a technology with which we can copy your brain, that is, what you really are, transmit its state over a distance with instantaneous (or almost instantaneous) speed, and then – the most interesting thing – put this state into another brain. Now for the even more curious part. You have probably all seen how under the influence of hypnosis a person becomes, to put it mildly, a different personality. It is as if the body remained, but the consciousness, the personality became different. Similarly, in this case, when realizing such an influence, the consciousness, getting into a new body, puts that brain as if in a coma state, that is, it disconnects it, and then acts on its own. Besides, a timer program will be laid down, and it, this first mind, will switch off at the appointed time and return to the original body. And the person from which the mind and consciousness were sent will then know and remember everything that he felt in another's body. Here is a miracle, which is partially already real.
Imagine if someone had told you at the dawn of the invention of electricity that one day the whole world would be wrapped in wires. You would have said, "There are not enough resources for that, it is impossible to realize. Wouldn't you? And now think… if I tell you that such installation, which probably will not differ much from virtual reality installation, will become a common commodity, and such flights to parallel worlds will be entertainment and attraction. Well? You'll say: here it carries. Discoverers have always fled from primitive consciousness to the depths of space. Let's get rid of primitive consciousness.
Some will say, "Wait, wait, wait, let's deal with it on Earth. Let's assume that all this is true. The technology of consciousness transfer already exists. Quantum teleportation is known to science. But tell me, please, what makes you think that there are these parallel worlds?
I'll answer: it all comes from what I said. I was talking about quantum entanglement. That is to clarify: entanglement is not from the word "entanglement", but from the fact that one particle has a double, which allows parallel reality, somewhere its state changes with instantaneous speed. Repeats the particle like you in a mirror – your reflection.
Quantum teleportation provides the answer to the existence of these worlds. It's hard to believe, but it does. It's been going on for billions of years. We're all made up of these particles. We know what photography, x-rays, tomography are, and it doesn't surprise us anymore. What's that… cloning and genetically modified foods don't even surprise us. So why not assume that our whole world, consisting of molecules, atoms, particles and so on, emitting all this every second, has not folded into the same world in another area, where the appropriate conditions exist. Why shouldn't that be allowed to happen? So, logically speaking – all of this is there, is there in numerous forms, that is, one world is reflected in another, and that one in a third, and so on. Of course, with each copy, and taking into account the conditions around, the subsequent world will already be a little different.
As for the practical part, I think there are not enough fingers on my hands to list in what areas and for what purpose this process can be used. For example, even in Earth conditions it is possible to create several clones of one person, settle them in special agencies, in different parts of the world, and the sought person can instantly transfer consciousness across oceans and continents, remaining herself. It's the same in those worlds. Initially, once there, the same technological setups and the same clones can be created. That is, traveling to far and distant space will not be a problem at all.
