In a multiverse theory, multiple universes coexist. They all share some fundamental laws of physics but may differ in their specific details. To describe the evolution of these universes, physicists use a set of equations known as the “best equations”. These equations are based on the laws of physics that govern the universe we live in, and they allow scientists to make predictions about the behavior of other universes.
The best equations are important because they provide a way to understand the evolution of the multiverse. By studying these equations, scientists can learn about the different ways that universes can form and evolve. This knowledge can help us to understand our own universe and its place in the multiverse.
