At the start of the 20th century with the findings of the Theory of Relativity and Quantum Physics, Modern Physics did away with the fixed Newton conception of the world. Matter is no longer regarded as static and passive, but as a dynamic active “bundle of energy” which is in a state of constant flux. The traditional concepts of time and space, of isolated objects, and of cause and effect have lost their importance.
In modern Physics the universe is a dynamic indivisible whole which always necessarily also includes the observer.
