1+3 Spacetimes? Are we subluminal entities in superluminal universe?

In modern physics, our understanding of the universe is typically based on the concept of 4-dimensional spacetime, consisting of three dimensions of space and one dimension of time. However, there has been ongoing research and discussions in the physics community about the possibility of a universe made from 1 space and 3 time dimensions. This idea challenges the conventional understanding of spacetime and raises new questions about the nature of time and the structure of the universe. Some scientists believe that a 1 space and 3 time dimension universe could potentially provide new insights into long-standing mysteries in physics, such as dark matter and the unification of quantum mechanics and general relativity. In this new topic, we will explore the concept of a 1 space and 3 time dimension universe, its implications and current understanding, as well as the ongoing debates and discussions surrounding this exciting area of physics research.
