Only questions about the results of experiments have a real significance and it is only such questions that theoretical physics has to consider.

Is the basic law of radioactive decay exponential

P.M. Gopych, I.I. Zalyubovskii

Basic theoretical approaches to the explanation of the observed exponential nature of the decay law are discussed together with the hypothesis that it is not exponential. The significance of this question and its connection with fundamental problems of modern physics are considered. The results of experiments relating to investigation of the form of the decay law are given.

How Real is Incomputability in Physics?

José Manuel Agüero Trejo, Cristian S. Calude, Michael J. Dinneen +4 more

A physical system is determined by a finite set of initial conditions and "laws" represented by equations. The system is computable if we can solve the equations in all instances using a "finite body of mathematical knowledge". In this case, if the laws of the system can be coded into a computer program, then given the initial conditions of the system, one can compute the system's evolution. Are there incomputable physical systems? This question has been theoretically studied in the last 30-40 years. In this paper, we experimentally show for the first time the strong incomputability of a quantum experiment, namely the outputs of a quantum random number generator. Moreover, the experimental results are robust and statistically significant.
