The multiverse theory is limited to 4 levels because it is based on the concept of the observable universe. This means that the theory only applies to the portion of the universe that we are able to observe, and beyond that, we cannot make any assumptions about the existence of other universes. The 4 levels represent the different possible states of our observable universe, including the laws of physics, energy levels, and matter distribution.
The number of levels in the multiverse theory is determined by various factors such as the laws of physics, the energy levels of the universe, and the distribution of matter. Scientists use mathematical models and observations from experiments and observations to determine these factors and ultimately determine the number of levels in the multiverse theory.
While the current understanding of the multiverse theory is limited to 4 levels, it is always possible for new evidence or discoveries to lead to a revision of this theory. As our understanding of the universe and its laws continues to evolve, it is possible that the number of levels in the multiverse theory may change in the future.
The evidence supporting the existence of only 4 levels in the multiverse theory comes from various sources, including observations from the cosmic microwave background, particle physics experiments, and mathematical models. These sources provide evidence for the laws of physics and energy levels that are consistent with the 4 levels in the multiverse theory.
The levels in the multiverse theory are not fixed and can change over time as our understanding of the universe and its laws evolves. New evidence or discoveries may lead to a revision of the current theory and potentially change the number of levels. Additionally, as the universe continues to expand, it is possible that new levels may emerge. Therefore, the levels in the multiverse theory are not static and may change over time.
