The man outside the pub insisted he invented the word placisity in 2001, but it's still not in the dictionary. This made him angry. He was not in a state of placisity.

Theory of the Plasticity of the Laws of Physics

A theoretical framework proposing that the laws of physics can undergo permanent deformation—that under extreme conditions, they might change in ways that don't revert when conditions normalize. Unlike elasticity (temporary stretching), plasticity implies irreversible transformation: the laws themselves could evolve, learn, or adapt over cosmic time. This theory suggests that the universe's laws might not have been fixed at the Big Bang but might have developed through cosmic history, perhaps through mechanisms analogous to natural selection (universes that produce stable laws persist) or phase transitions (laws crystallizing as the universe cooled). The plasticity of physical laws opens possibilities for cosmic evolution far beyond what traditional physics imagines—a universe whose fundamental rules can change.
Theory of the Plasticity of the Laws of Physics Example: "Her theory of the plasticity of physical laws suggested that the constants we measure today might be different in the distant future—not because anything changes, but because the laws themselves evolve. The universe isn't just unfolding; it's learning new rules."
