Alexander Franklin Mayer is an American independent theoretical physicist and author who works outside the academic mainstream on questions in relativity, gravitation, and cosmology. Writing under the self-styled title "Jay Pritzker Fellow in Theoretical Physics," he is best known for arguing that the standard, or "canonical," model of cosmology is fundamentally mistaken and that phenomena attributed to dark energy can instead be explained by a reinterpretation of the geometry of time. His views are not accepted by the physics community and fall outside established consensus.

Biography

Mayer works as an independent researcher based in the San Francisco Bay Area, publishing through his own imprints and websites rather than through a university appointment. He has presented his ideas under the banner of the "Jay Pritzker Foundation" and the associated title "Jay Pritzker Fellow in Theoretical Physics," and maintains an online presence at sensibleuniverse.net, the blog afmayer.blogspot.com, and the social-media account @GeometryOfTime.

In December 2010 Mayer prepared a paper for circulation among participants of the workshop "Experimental and Theoretical Challenges to Probing Dark Energy," which was sponsored by the France-Stanford Center for Interdisciplinary Studies. His work has otherwise been distributed primarily through self-publication and online forums rather than peer-reviewed journals.

Scientific contributions

Mayer's central thesis, developed in his book and accompanying manuscripts, treats local proper time as a geometric object and, on that basis, offers an alternative interpretation of gravitational redshift and of cosmological redshift. From these considerations he argues that the observed dimming and reddening of distant objects does not require an accelerating, dark-energy–driven expansion of the universe.

Building on this framework, Mayer contends that redshift–magnitude and galaxy population-density data from surveys such as the Sloan Digital Sky Survey (SDSS) and the 2dF Galaxy Redshift Survey are in tension with the standard Lambda-CDM model. In place of the canonical model he proposes a cosmology that he describes as reviving de Sitter's 1917 solution of the Einstein field equations, derived from arguments of symmetry, and he characterizes the resulting universe as "boundaryless yet finite." He has claimed that his approach naturally addresses a number of outstanding anomalies in standard cosmology, including the Hubble tension, the σ8 clustering discrepancy, the lensing anomaly, and large-angular-scale anomalies in the cosmic microwave background.

These proposals depart from established derivations in general relativity and Big Bang cosmology and have not been adopted or corroborated by mainstream researchers; discussion of his manuscripts has largely taken place in "against the mainstream" online venues rather than in the professional literature. His book On the Geometry of Time in Physics and Cosmology was self-published (Serenford Scientific Press, 2009; ISBN 978-0-615-28941-0), and an expanded version bearing the longer title On the Geometry of Time in Physics and Cosmology and the Fall of the Canonical Cosmological Model was released in 2011.
