In a recent study, a Canadian expert claimed that the age of the universe should be adjusted to 26.7 billion years, as opposed to the generally accepted age of 13.7 billion years. the University of Ottawa A study I published revisits theories regarding galaxy formation and the associated physical processes.
What exactly did the scientists achieve?
The research deals with the analysis of the redshift of distant galaxies, with the help of which the age of the universe has been previously calculated. Based on the accepted Lambda-CDM model, this value is 13.797 billion years. However, the star HD 140283, nicknamed Methuselah, which is only 190 light-years from Earth, originally appeared to be more than 14 billion years old, raising a discrepancy about the age of the universe. However, later research gave the star’s age as only 12 billion years. In addition, the James Webb Space Telescope discovered galaxies that existed only 300 million years after the Big Bang. These galaxies are very advanced and appear to be mature regardless of mass, although current theories suggest they will need more time to form. All this leads to observations that are not currently fully explained.

According to the researchers, if we give physical constants a chance to evolve, some galaxies spotted by the James Webb Space Telescope could be much older, even by billions of years, not just a few hundred million years after the Big Bang. This would explain how galaxies that are thought to be young, advanced, regardless of their mass, can be as mature as older galaxies.
However, the theory should be approached with reservations. Primarily because it includes neglected theories previously rejected by science. In addition, the claim that the universe is twice as old as currently accepted contradicts several theories that have been reliably proven. In any case, there are many reasons why we should treat these ideas as scientific curiosities rather than true innovations.
