Ottawa, Canada (SPX) Jul 12, 2023
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."
"Our newly-devised model stretches the galaxy formation time by a several billion years, making the universe 26.7 billion years old, and not 13.7 as previously estimated," says author Rajend

The mystery of the first galaxies of the universe is an indomitable urge of human beings. The formation of them is mastered by the nature of dark matter which is also one of the most important problems faced by fundamental physics. However, understanding the nature of dark matter-for example, whether it is cold or warm-and its subsequent effect on the first galaxy formation is a huge challenge.
