Accurate Predictions of Gravity without Mass, Null Dark Matter Results, Muon Precession and Solutions to the Hubble Tension, Final Parsec Problem, Information Paradox, Inter Alia: A 3.5-Year Status Report on the Probabilistic Spacetime Theory
The Probabilistic Spacetime Theory (PST) was first referenced in 2020 and published in complete form in 2021. The theory exists to facilitate developments in modern cosmology through specific predictive and explanatory assertions, both to drive and interpret research discoveries. This article describes an extensive appraisal of the theory’s demonstrated predictive accuracy and explanatory efficacy during its 3.5-year lifetime. The theory was found to have forecasted multiple astrophysical and cosmological findings such as black hole expansion without mass, gravity without mass, an excess degree of muon precession beyond the Standard Model prediction, and the self-interaction of so-called “dark matter”. Research outcomes concerning the Hubble tension were also predicted and explicated. Additionally, the PST was found to offer explanations concerning many baffling observations, including the existence of primordial supermassive black holes, the ubiquitous existence of magnetism, and unexpected heat in intergalactic hydrogen clouds. Enigmatic high-profile theoretical issues were also addressed by the PST, including the black hole information paradox, black holes without a singularity, and the final parsec problem. Overall, the theory seems to have demonstrated substantial predictive and explanatory utility during its short lifetime. To facilitate further testing of the PST, predictions of current studies’ outcomes are offered.
