An Alternative Theory to both Special and General Relativity: Greater Accuracy and Simplicity

The theory of world membranes, recently proposed as an alternative to both special and general relativity, is an axiomatic system grounded in four simple, physically meaningful principles. This theory is consistent with all current experimental and observational data. For example, it shows that frame transformations reduce to Lorentz transformations after local linearization, and it predicts motional and gravitational time dilation, as well as length contraction. Unlike relativity, it proves the constancy of light speed measurement locally, rather than assuming it as a principle. The theory also provides precise predictions for phenomena such as planetary precession and gravitational lensing, while reverting to Newtonian mechanics in low-speed and weak-gravity conditions.

This new framework is simpler than relativity, both in its core principles and practical applications, while improving accuracy by addressing gaps between existing theory and experimental results. It solves open problems such as dark energy and dark matter, and resolves issues like the twin paradox, as well as the flatness and horizon problems. Additionally, it leads to singularity-free models of black holes and the evolution of the universe, while offering predictions that diverge from relativity, awaiting experimental verification.
