Is the universe 26.7 billion years old?

A new study shows that the universe could be twice the known age. The study, based on the early galaxy data from the James Webb Space Telescope, proposes that the universe is actually 26.7 billion years old and that the light from these distant galaxies has been "tired" by its long journey through space. This would explain why the galaxies appear to be more massive than they should be. The study combines the century-old tired light hypothesis with the covarying coupling constant model to explain the nature of the galaxies discovered by Webb in the early universe. It is controversial, and other astronomers are not yet convinced that the universe is twice as old as we thought. However, if more evidence is found in favour of this new model, it could replace the currently accepted cosmology model and solve several astronomical problems.
