Parallel Worlds pro et contra - стр. 84
– I'm curious," Iulia was the first to answer.
She was the most active.
– I'm intrigued too," Catherine replied.
– I hope you don't need a degree to understand," Andrian said a little jokingly.
YatSan remained silent, but she signaled with a look that she was waiting for more information.
– So, let's begin. I have to tell you about such a topic as the theory of multiworld interpretation. Don't ask me what, why and why yet. I told you from the beginning – you have to believe me. For you little by little my story, training, what is happening – everything will be put together like pieces of a mosaic into a picture. Consider that you yourself are picking up the puzzles to understand the overall meaning. Going further. Let's say, for example, we are living in ancient Egypt at the moment of completion of the construction of the pyramid of Cheops. Tell me, was it a grandiose event?
Before they could react in any way, Ruthra himself answered:
– Yes, you're going to say it's huge. And I will say, yes, it's grandiose, comparable to the first human space flight. And what would you say at that time if someone asked you to explain the existence of molecules or the structure of the solar system? You would have considered it magic, devilry and fantasy, if not to say nonsense. So now in our world quite serious scientists, and for a long time already, consider the existence of parallel worlds. Yes, yes.
Ruthra took note: although their faces remained serious, a slight chuckle ran through them.
– Let's hear what science has to say about it. A multiverse is a hypothetical set of all possible real-life parallel universes, including the one we are in. According to the hypothesis of Hugh Everett, the creator of the many-worlds interpretation of quantum mechanics, we live in a universe, or rather, a multiverse, in which many successive worlds are constantly being born and branched off, each containing a different version of you. I'll tell you right away – don't try to memorize everything by heart. We will come back to this topic many times, and I will give details, explain everything. So, physicists who studied this topic used the many-worlds interpretation to explain the incomprehensibility of the Copenhagen interpretation, namely, the statement that an unobservable phenomenon can exist in two states. There is the Copenhagen interpretation, Everett's many-worlds interpretation, and a bunch of other theories, but these are the main ones. So instead of saying that Schrödinger's cat is both alive and dead – the many-worlds interpretation says that the cat has simply "branched off" into different worlds: in one it is alive, in another it is dead. Now here we need to sort of move on to this cat.
