Time might not be a real part of the universe, but just a side effect of things trying to relax.

The Takeaway
We usually treat time as a background stage where everything happens. This new theory suggests time is not fundamental at all; instead, it 'emerges' when local systems try to resolve conflicts in their own physics. It is like saying the 'tempo' of a song doesn't exist until the instruments start trying to play together. If this is right, our entire understanding of history and the future is just a simplified limit of a much weirder underlying process. It brings us one step closer to figuring out why the 'arrow of time' only points one way.
From the abstract
Classical dynamical laws are conventionally formulated as closed evolution equations defined on fixed geometric backgrounds and a global time parameter. We develop a formulation in which neither prescribed evolution laws nor an external clock are assumed a priori. Grounded in the principles of conservation, locality of interaction, and independent local frame freedom, the framework treats spatial geometry as a relational structure that may evolve together with the state. We introduce a notion of
