Evaluation of Theories and Methodologies: Relativistic Physics vs. the Dynamic Universe — With Remarks from Physics and Reality 2024 and Cosmology on Small Scales 2024 Conferences

In the classical ideal, a physical theory provides understandable dynamic explanations and yields novel predictions of phenomena. Relativistic Physics (RP), namely the special and general theories of relativity and relativistic cosmology, does not meet the classical ideal. This discrepancy has been addressed by transforming the classical ideal into a ‘relativistic methodology’, where it is accepted that nature is not fully understandable, predictions are prioritized over dynamic explanations, new phenomena may be accommodated in an orderly fashion with the aid of additional hypotheses, and anomalous data may be disregarded. Relativistic methodology and the enduring confidence in RP stem from tradition, where physicists who have learned to conceptualize reality through RP see it as the only alternative. The greatest 20th-century philosophers of science —Karl Popper, Thomas Kuhn, Imre Lakatos and Paul Feyerabend— have taught us that to fully understand a theory’s weaknesses, it must be juxtaposed with an alternate theory, and that its replacement requires a superior theory. Here, RP is confronted with Tuomo Suntola’s Dynamic Universe (DU). Suntola claims that DU matches or surpasses RP’s predictive accuracy for several central phenomena from the terrestrial to the largest cosmological scales, while adhering to the classical ideal and cohering with quantum mechanics. If this claim withstands scrutiny, DU deserves further attention from physicists, philosophers and funding institutions.
