Controversy over the true age of the universe

The first clear image of the universe was released by the James Webb telescope last year.

The James Webb Space Telescope's initial observations of the universe cannot be explained using the current consensus cosmological models, which estimate the universe to be about 13.8 billion years old, based on the concept of expansion following the Big Bang.

In an article on The Conversation on August 29, a team led by cosmologist Rajendra Gupta, a lecturer at the University of Ottawa (Canada), proposed a new model showing that the universe is probably 26.7 billion years old, based on new observations by the James Webb telescope of the universe's earliest galaxies.

Images of early galaxies show some date back to the dawn of the universe, 500 to 800 million years after the Big Bang, but their shapes are like galaxies that have evolved over a long period of time.

Smaller galaxies, on the other hand, are more massive than larger-looking galaxies.

In a report published in the journal Monthly Notices of the Royal Astronomical Society , Professor Gupta used a "hybrid" model, which means mixing several different models to create a new model to explain the observations of the James Webb telescope.

Accordingly, he believes that the universe must be older than long-standing hypotheses so that galaxies have more time to develop to the impressive levels recorded by the James Webb telescope.

The University of Ottawa lecturer also said that new observations from the James Webb telescope are pushing experts to think in new physics directions in an effort to reach a consensus to explain the James Webb observations.
