fly with the Sun and the entire solar system around the center of the galaxy at about 250 kilometers per second and make a circle in about 220 million years. So there you go. By the way, if you send hi… Oh, I completely forgot about that example.
Laughs were heard in the hall again.
– Yeah, I was gonna say about the hello from the nearest star. Well, if our neighbor sends us a hello at the speed of light, we'll get a hello in four years. And to fly on a spaceship, even with the speed that is unthinkable for living organisms, and is possible only for unmanned ones (see my articles about the effect of space radiation on living organisms, we have to fly…), as they say, a hundred lives will not be enough. That's me talking about that man-made machine with the highest speed. And that's just to the neighbor. Now let's go back to the new hello and send it from one edge to the edge of our galaxy. Sorry, you'll be waiting 100,000 years. And that's at the speed of light. And that fastest machine takes hundreds of millions of years. It'll take two million years for our letter to reach Andromeda. And this is at the speed of light, which is not only unthinkable in terms of achieving technical devices, but also contradicts all the laws of physics for material bodies. Again, if we remove the same radiation, which will blind everyone even in the flight to Mars. These are the extremes. On the one hand, we cannot reach such a speed for material bodies, because according to the famous formula the mass should be infinite, and on the other hand – even if we reach it, it is still negligible for cosmic distances. No material body can reach the speed of light. When you drive a car or fly in an airplane, or even ride a merry-go-round – you feel when you are pressed to the seat. That is, as your speed increases, your mass increases. Not your personal weight, but your mass. Only immaterial particles can fly at the speed of light. And there are such particles. There's a mystery to it… Now, I'll introduce another technology. It may seem like sorcery to you, but agree – the experiments of alchemists were also sorcery. This is the technology of transmitting thoughts, our consciousness over a distance. Now you will say: it is impossible to transmit them at all. But I will tell you – it has been possible for a long time… and at a distance too. After all, what is the totality of information, books, movies, our negotiations? They are our converted thoughts. Some into radio waves and then into sound speech, others into pictures and our visual perception… and so on. And if you can express part of the thoughts, part of the consciousness, why can't you express all of our consciousness in some form. And I'm telling you, you can. Consciousness can be recorded in the same radio waves or photons of light, then sent, and then decoded. You speak – and your voice is recorded, video is recorded, and then it travels earthly and cosmic distances. And then it is played back on another device. It, that device, doesn't see the same image that was there originally. And how does the image appear at all? The reflection of sun rays from the material body gets into the camera, just like in your eye, and there it is transformed, converted into a form understandable for the brain. That's why a man sees the world in his own way, a snake in its own way, a fish in its own way, and so on. Now imagine if all these animals had intelligence. But that's later.
Ruthra waved his hand, then held his index finger up.
– That's me on the subject of other worlds. Looking ahead, I will say: and you will remember those optimal options that allowed only humans to have intelligence, if there are intelligent beings, according to my theory…
He put his finger up again, and afterward he said pathosily:
– They're just like us.
After a little silence, he continued:
– We're focusing on something else for now. When radio waves… or light waves, even reflections from mirrors… travel colossal distances, are transformed into a form we understand, recorded by us, and then, even after a long time, give us the same information we had at the beginning – we see nothing surprising in it. So why can't we record consciousness, then transmit it over a distance and…" he repeated his signature gesture, "inject it into a person. Into another human being. And I'll tell you this: not just another person on Earth, but another person altogether. Not an earthling.
The last word he said again stretched out.
– Here, of course, we should remind about cloning technology. It is possible to put your consciousness into your clone. You're going to say, "How so? And you'd be right. After all, you are your consciousness. And if someone has your consciousness, then they share your past. Yes. But the future is different for everyone. From the moment your consciousness enters the clone, it's a separate person. You either have to disconnect, let's say, the first body… or… you have a twin. There are thousands of twins. And they all have the same past and individual futures. It's another thing to find that body somewhere out there, far out in space.
Ruthra looked around the audience, paused for a moment.
– I don't see the ridiculousness.
The hall was not left in debt, almost everyone smiled.
– There is another technology for this. This product is based on logical thinking. And logical thinking is based on two facts – infinite time and infinite space. Yes, they are infinite. It is difficult for us to imagine it, because we try to imagine a huge distance, some grandiosely large time, and for infinity they turn out to be minuscule. Imagine if you have to walk the circumference of the equator. Now imagine that to the sun. How many stars are there in our galaxy? About 400 billion. Imagine that this is a beach and every planet on it is a grain of sand. How many grains of sand are there on our planet, even around one sea? Can you imagine a galaxy with billions of stars? How about billions of galaxies? If only in ours there are about 400 billion stars, each with planetary systems… Isn't there a possibility that the Earth will form? You'll say, maybe, yes. This is where we get to the Fermi paradox. As you know, it says, if they exist, where are they? That is, over millions, billions of years of development, they must have reached or surpassed the level of our civilization, and we must have seen traces of their activity. Some kind of spacecraft, some kind of radio conversations. Perhaps we don't see all these things because they haven't reached us yet. Not even radio waves. Think about it, even at the speed of light, radio waves take an extremely long time to propagate for human life, even a technical civilization. Well, let's say they sent a signal. Now let's do the math. Our galaxy is 100,000 years across. That's for radio waves to travel through it. They too, as we know, travel at the speed of light. If this civilization took the path of scientific development 10,000 years ago, even if they already invented radio 5,000 years ago, and they are 20,000 light years away, we don't yet know what will happen in 15,000 years on Earth. Catch a thought. Maybe we'll destroy ourselves and never hear them at all, even if the signal gets through. Or we might hear them in 15,000 years. Maybe our signal will reach habitable planets that are 30,000 light years away. Or maybe the habitable planet is in our neighboring galaxy, the Andromeda Nebula, which is 2 million light years away. In 2,000,000 years, we will hear from them… or they will hear from us. So the answer to the question of whether or not they are there is probably there. And I'll tell you, of course there are! It's logic that says they must be. This is the basis for the following paradox. The theory of many-worlds says that there can exist simultaneously many worlds, and absolutely identical, with identical properties, as if parallel, that is, some of them, it is assumed in this theory, are not parallel, not fantastic, really exact copies of ours.
Rutra did his crowning trick again, looking at his listeners with a testy look.
– A miracle is a miracle to be beyond our everyday understanding of reality. The idea is that what happens in our world is somehow reflected in that world. Fantastic? Quite. But only if it is said of a phenomenon on our planet, as if it were a real invisible parallel world. And then – although it depends on how you look at it. And in the infinity of time and space why not to assume the existence of this reality, especially since we accept the theory of probability. There is a certain logical regularity and paradox at the same time. The point is this: you know very well that there is an antiproton, i.e. a representative of antimatter, a substance with opposite properties. Science is working on how to find other substances, or rather, antimatter. If there is such a reality, substances with opposite properties, then on this basis another logic is formed. If there is antimatter, substances with opposite properties, not the ones we are used to – what kind of world do they make up? An opposite world? Then perhaps there is an
