For many years I have been interested in the question of how the universe performs calculations. Why our calculations require colossal resources. It is very difficult for us to model not only the absorption of a star by a supermassive black hole, but even the behavior of an ordinary, at first glance, liquid. What can I say about liquids? Even an atom more complex than hydrogen is difficult to model. And the more accurate our model, the more impossible our calculations become. But in nature, even in familiar conditions, an incredible number of interactions occur. And in space the scale of events is even more colossal. And somehow no lags are noticeable.
It would seem a difficult question. And our minds cannot understand how this can be realized. However, it seems that everything is very simple. If we accept that all matter we perceive is a perturbation of quantum fields, then everything comes down to the superposition of waves in quantum fields.
P.S. If only it were so simple to understand what quantum entanglement is…
