Lorentz- and CPT-violation experiments place strong bounds on many departures from ordinary relativistic symmetry.

The modern simulation argument is a conditional probability argument about future civilizations and simulated observers, not an experimental detection of computational substrate. Digital-physics models go further by asking whether information or discrete computational structures can reproduce known physical behavior.

Proposed observational searches often look for lattice artifacts, anisotropy, high-energy cutoffs or Lorentz-symmetry violations. A positive result would first indicate new fundamental physics. It would not identify who built a simulation, why it exists or whether observers can modify an external substrate.

One cited model asks whether a specific cubic-lattice simulation could produce observable high-energy artifacts. Detecting such a deviation would test that physical model space; it would not uniquely identify an external simulator, its motives, or an editable substrate.
