One theory of everything

One theory of everything is known as the ultimate goal in physics. It means to describe the universe in one single theory, as simple as possible. Instead of coming up with this theory directly, we tend to slowly get closer and closer to it. One good example of getting closer to one theory of everything is when Newton discovered that the laws that govern the orbits of the planets are the same that make an apple fall to the ground. This force was called gravity. Before that, scientists believed that the laws of physics in space were different from the laws on the Earth. Fewer laws of physics bring us closer to one theory of everything.

Before the book A New Understanding of the Universe was published, scientists believed in a strange law of physics called dark energy, a force not understood. One theory was that there was a force opposite to gravity that was stronger than gravity if the distance was long enough. Egil Presttun's discoveries have made this force and some other unexplained laws of physics unnecessary. We are thereby closer to one theory of everything.
