Three-Dimensional State Universe

The traditional four-dimensional spacetime framework, which treats time as an instrumental parameter, fails to explain many physical phenomena. This paper proposes the Time-Sequence Theory of the Three-Dimensional State Universe, establishing mass, energy, and time-sequence as the three fundamental ontological dimensions of the universe and clarifying the substantivity and driving nature of time-sequence. Based on the correspondence between time-sequence and the Lorentz factor, the time-mass equation (m=τc2) and the time-energy equation (t=Ec2) are rigorously derived. A combined time-mass-energy conservation law is established, proving that traditional mass-energy conservation is a special case under constant time-sequence. The theory is fully compatible with special relativity and can be directly verified through experiments such as the acceleration of nuclear isomers. It provides a testable new framework for understanding the universe and innovating the paradigm of fundamental physics.
