Busy Beaver–based bounds as physical laws of growth and convergence
Establish that, in our universe, directly measurable physical quantities obey the Busy Beaver–derived bounds on rates of change—specifically, that no such quantity can grow faster than Radó’s Busy Beaver function BB(n) or slower than its inverse BB^{-1}(n), and that no such quantity can converge to a finite value faster than 1/BB(n) or slower than 1/BB^{-1}(n)—thereby confirming these limits as genuine physical laws.

I conjecture that these limits are novel physical laws governing which rates of growth and convergence are possible in our universe.
