Heisenberg's uncertainty principle is one of the most famous and perhaps wrongly understood ideas in physics. This principle tells us that in nature there is fuzzines, which is the fundamental limit of what we can know about the behavior of quantum particles. Namely, we can only determine the movement and behavior of quantum particles with the probability. Unlike the universe, as Isac Newton defined it, where everything is determined and predictable, if we know the initial conditions, according to this principle there is a level of fuzzines in quantum theory. Some of Heisenberg's ideas are that the vacuum is not empty, and that energy is not continuous, but that it has come in discrete packages (quanta), and that light can also be described, at the same time, as a wave and as a stream of these quanta. However, this means that everything that is considered objective and intuitive is questionable. This theory is known as counter-intuitive.
