New physics model proposes universe is twice as old, no dark matter needed

A pair of researchers from the University of Ottawa, Rajendra Gupta and Nikolaos Samaras, have developed a controversial new cosmological model called CCC+TL (Covarying Coupling Constants plus Tired Light). Their framework challenges the standard Lambda-CDM model by suggesting physical constants slowly change over time and that light loses energy during its journey across space, eliminating the need for dark matter and dark energy. Based on their calculations, this model would make the universe approximately 26.7 billion years old—roughly twice the currently accepted age of 13.8 billion years.

The implications are profound for both cosmology and physics. If validated, this would rewrite our fundamental understanding of gravity, cosmic expansion, and the universe's timeline. For scientists and engineers, it represents a radical alternative to decades of research built on dark matter theories. The takeaway is that an audacious new model is attempting to solve cosmology's biggest mysteries with a simpler, but far more ancient, universe.
