New Model Claims Universe Is 26.7 Billion Years Old Without Dark Matter

Researchers at the University of Ottawa report that an alternative cosmological framework successfully matches several major astronomical observations. The model proposes that the universe is 26.7 billion years old, nearly double the widely accepted age of 13.8 billion years. It also suggests that dark matter and dark energy are not necessary to explain cosmic behavior.

Testing the Alternative Framework

The model is known as CCC+TL, which stands for covarying coupling constants plus tired light. Instead of relying on invisible components, the theory suggests that forces and particles change over time due to shifting fundamental physical constants. Researchers tested the framework against light elements created after the Big Bang, cosmic chronometer measurements, and galaxy rotation curves, finding consistent results without invoking dark matter.

Explaining Early Galaxies

One major puzzle in modern astronomy is the discovery of surprisingly large and mature galaxies in the early universe. The standard model struggles to explain how these structures formed so quickly. Under the alternative framework, the universe had billions of additional years to develop during early cosmic history. This extra time could help explain how massive galaxies emerged much earlier than previously expected.
