I promise that after this video you will look at quantum mechanics differently, and maybe even understand something. After all, modern science completely changes our understanding of it. For example, today scientists can conduct a double-slit experiment with a controlled collapse of the wave function, thereby forcing us to adjust all the most well-known interpretations of quantum mechanics. Moreover, this experiment is no longer carried out with elementary particles such as a photon or an electron, but with real huge molecules of several thousand atoms. But what is amazing is that in the near future, this figure will grow to millions of atoms. Such dynamics make you wonder, where is the real border between the quantum and classical worlds? Will we be able to scale quantum properties to the size of some animal or even a person. In any case, quantum mechanics is already moving to a scale where gravity begins to make a significant impact. It begins to intertwine with the general theory of relativity, which is practically incompatible with it. Which, in theory, expands the search area for quantum gravity, but at the same time creates unacceptable situations, for example, when different quantum states of an object will create different gravitational fields superimposed on each other. That is, space-time itself will be in a superposition. And these are not some interpretations or hypotheses. This is a foreseeable scientific future, lying on the path of revolutionary scaling of modern quantum computers. I understand that at first this may seem incomprehensible and complicated. However, I will try to explain everything as clearly and in simple words as possible. As usual, it will not be easy in places, but I am sure that you can handle everything. And to understand everything, we will answer the questions: What is a wave function and superposition? What is quantum decoherence? How is quantum mechanics related to gravity? And finally, where is the boundary of the quantum world? ______________________________________________ LEAVE A TIPS FOR COFFEE????: via the link: https://www.donationalerts.com/r/veli... on boosty: https://boosty.to/velikohatskiy/donate to the SBER card: 4276 3802 0263 9097 (Andrei V.) _______________________________________________ SOCIAL NETWORKS: I'm on Boosty: https://boosty.to/velikohatskiy I'm on Telegram: https://t.me/velikohatskiy I'm on Instagram: https://instagram.com/andrei_velikokh...
