Understand the tunnel effect. Well, imagine you have a tunnel of 2.8 meters high and a lot of trucks of 3+ meters high that come to the entrance, unfold and go back. It is clear that trucks in principle can’t be on the other side of the tunnel, but they get there from time to time! And if you try to find out from the drivers how they succeeded, no one will be able to answer, they will only shake their shoulders and say, "I go up to the tunnel, I see the mark 2.8 and I understand - well, I came, I am just going to turn and suddenly I am on the other side. How is? He knows it" The tunnel effect cannot be understood, it can only be accepted.
