Louis Marmet is a Canadian experimental physicist whose work spans precision spectroscopy, atomic clocks and time metrology, as well as the critical study of astronomical redshift and alternative, non-expanding cosmologies. He is the son of the physicist [/php/index.php?tab0=Scientists&tab1=Scientists&tab2=Display&id=148 Dr. Paul Marmet], with whom he shares an interest in questioning the standard Big Bang model, though the two are distinct researchers.
Biography
Marmet earned his Ph.D. from the University of Toronto and pursued a career in experimental atomic and optical physics. He worked at the National Research Council of Canada (NRC), where he contributed to the development of Canada's primary frequency standards, including work on the NRC cesium fountain atomic clock that realizes the SI second. He later became an adjunct professor in the Department of Physics and Astronomy at York University in Toronto, where he has continued research on high-precision optical and microwave spectroscopy of atoms, atomic clocks and time standards, and real-time digital instrument control.
Alongside his laboratory work, Marmet has been active in the community of researchers who examine the foundations of modern cosmology, and he has participated in the Chappell Natural Philosophy Society (CNPS). He is a contributor to and organizer of "A Cosmology Group," an online forum that compiles peer-reviewed literature and alternative models bearing on the interpretation of the cosmological redshift.
Work
Marmet's experimental research has centered on precision frequency generation and measurement, nonlinear optics, laser (optical) cooling, and the physics of atomic clocks. At the NRC he collaborated with colleagues such as Pierre Dubé and Christian Gigault on the construction of the NRC cesium fountain frequency standard, and he took part in experiments testing the one-way isotropy of the speed of light.
In cosmology, Marmet is known for a systematic 2018 survey of proposed redshift mechanisms, in which he catalogued and quantitatively compared more than sixty physical processes that have been advanced to explain the spectral red-shift of distant astronomical objects, including the solar-limb redshift, the redshift of quasars, and the cosmological redshift-distance relationship. He has proposed and studied a "spectral transfer redshift" (also described in the context of a Static Cosmology with Stimulated-Transfer redshift, SSTz), a mechanism based on a stimulated-emission process between photons that preserves the propagation direction of one interacting photon. To support quantitative comparison, he has published online calculators for both the standard ΛCDM model and his static-cosmology alternative. His writings emphasize testing competing models against observational data rather than assuming any single framework.
