Adjunct professor, Physics, L’Université d’Ottawa/University of Ottawa
My current research interest is in astrophysics, cosmology, and general relativity, especially the dynamics of the universe under evolutionary physical constants beyond the standard model. I have shown that variations of constants are correlated and thus are not possible to observe as, in most observations, they cancel, e.g., lunar laser ranging, binary pulsar timing, gravitational lensing, and evolution of planetary orbits. I have hypothesized that the observed redshifts of distant galaxies are not only due to the expansion of the Universe but also caused by the photons losing energy due to cosmic drag while traveling over large distances.
I currently teach astrophysics and cosmology to senior undergraduates and graduate students. I enjoy teaching and learning through teaching.
We need to consider alternatives to dark matter that better explain cosmological observations

Do constants of nature the numbers that determine how things behave, like the speed of light change over time as the universe expands? Does light get a little tired travelling vast cosmic distances? It was believed that...
