Much more exists than we can ever measure or observe. There are phenomena that can’t be measured or observed in our Universe. Such as further away in the universe than our telescopes can observe or smaller than our microscopes can perceive.
Furthermore, other realities in parallel universes exist alongside our reality. These realities likely have completely different physical rules. With different particles, forces and rules no human can imagine.
But with the Multiversescope I can measure these different realities. This device can measure different kinds of particles and forces of other realities and model them.
