“Ognuno si sceglieva a propria immagine e somiglianza l'alfabeto di riferimento: per i matematici e i fisici erano i numeri, per i cristiani i miracoli, per i sognatori le nuvole.”

Cosmic Paradigm Shift: New Research Doubles Universe’s Age to 26.7 Billion Years

A new study proposes that the universe may be 26.7 billion years old, challenging the widely accepted estimate of 13.7 billion years based on the Lambda-CDM concordance model.

Our universe could be twice as old as current estimates, according to a new study that challenges the dominant cosmological model and sheds new light on the so-called “impossible early galaxy problem.

For years, astronomers and physicists have calculated the age of our universe by measuring the time elapsed since the Big Bang and by studying the oldest stars based on the redshift of light coming from distant galaxies. In 2021, thanks to new techniques and advances in technology, the age of our universe was thus estimated at 13.797 billion years using the Lambda-CDM concordance model.

However, many scientists have been puzzled by the existence of stars like the Methuselah that appear to be older than the estimated age of our universe and by the discovery of early galaxies in an advanced state of evolution made possible by the James Webb Space Telescope. These galaxies, existing a mere 300 million years or so after the Big Bang, appear to have a level of maturity and mass typically associated with billions of years of cosmic evolution. Furthermore, they’re surprisingly small in size, adding another layer of mystery to the equation.

Some theories like Zwicky's ''tired light'' theory, and Paul Dirac's ''coupling constants'' may be one of the possible explanations and putting the ''cosmological constant'' under possible revision.
