Parallel Worlds pro et contra - стр. 85

Ruthra looked at Andrian and noticed his desire to show his knowledge of the subject, but the girls didn't know, because it wasn't a woman's subject. So, with a nod, Ruthra continued:

– So, the cat experiment. It was presented to the world by someone very clever and imaginative – Uncle Schroedinger. What is the experiment? The point is that at the atomic level there are processes that are miracles and mysticism for our material world. These are such processes as, for example, a flying atom, which at first has the shape of a ball, but as soon as we decide to photograph it, that is, see it, it turns into a line. There are such oddities in the microcosm. It's as if this particle sees us, or rather, the observer, and appears in a different image. You may ask, how do we know that the atom was a ball before it was seen? And I will answer you: there is a trace that it leaves on the screen in front of it. It has to be recorded somehow, that it was there at all. I'll explain more about that later, but for now about this cat. It's actually a thought experiment. There is no cat. So, conditionally, we take a cat and put it in a box. We put a flask of poisonous gas, a radioactive atom and a Geiger counter. The radioactive atom may or may not decay at any moment, that's its nature. If it decays, the counter will detect the fact – and a special mechanism will break the flask with gas, and the cat will die. If it doesn't, the cat stays alive. Here's the one with and without surveillance. We close the cat in the box – from this moment, from the point of view of quantum mechanics, our atom is in a state of uncertainty: whether it has disintegrated or not. For us, while we are in ignorance, without precise observation, before we open the box and look in it – it will be in two states at once. And since the cat's life directly depends on the state of this atom, it turns out that the cat is literally alive and dead at the same time. That's how quantum theory depicts this situation. Now we move smoothly to the multiverse. So what's the point? In different variations it is as if the life of the cat, i.e. atom, and consequently – of all atoms and, of course, of everything that consists of these atoms – is under question: how it is there – in the world where another event happened. Here I will go a little bit ahead and say that we should add such a mystical phenomenon as quantum entanglement. This is such a thing, when two particles are friends, let's say, but they were separated, they scattered. Well, they're twins, let's say. So these twins can fly apart over incredible distances, but they can stay connected to each other. A bond so strong that it's instantaneous, faster than the speed of light. Of course, you don't have to know all the laws of physics, but I'll tell you that in our world, in our universe, there is nothing greater than the speed of light. No, because it's a law! But not in this case. Nevertheless, it is still a kind of mysticism: how and with what help they make this connection – no one knows yet. A miracle in the solid laws of exact science. It sounds delusional, but it is a fact. Here I have already told you about two mystical phenomena. Now, of course, you'll think: why did he gather us here and tell us such things? But you're interested, aren't you? Aren't you?
