The most important number for the physics world in the year 2023 was the number "1.25".
The research on particle physics had always stagnated when it came to the proof of the existence of high-dimensional space. According to the ADD phenomenological model's explanation of gravity and other forces, the world we observed was only a part of the higher dimensions. The electrons, protons, photons, and other particles in the Standard Model could not enter the higher-dimension, only gravitational field lines could.
The discovery of the Z particle gave a new explanation for the theory based on the phenomenological model.
The world we saw was only a fragment of the higher-dimensional space, the electrons, protons, photons, and other particles in the Standard Model might only be 3D projections of other particles in the higher-dimensional space.
