(NEW FRONTIER NEWS) – Astronomers are puzzled over new measurements that show that the universe is younger than some of the stars it contains.
The most precise measurements of the Universe’s age show that it is 13.8 billion years old with only a margin of error of only 20 million years in either direction based on the cosmic radiation left over from the Big Bang.
This measurement is contradicted by a star called HD 140283, which is nicknamed the Methuselah star, whose age has been estimated at being 14.5 billion years old. The star, which is 200 light-years away from Earth, has a very low iron content, which suggests it was made when iron was still not common in the universe.
“It’s a riddle of cosmic proportions: How can the universe contain stars older than itself?” physicist Robert Matthews wrote for The National.
“Astronomers now know it contains very little iron — which means it must have been formed before this element became common in the universe,” Dr. Matthew wrote, “And that implies HD 140283 must be almost as old as the universe itself.”
Dr. Mathews said that new research into gravitational waves could explain the discrepancy, but that it is early and could change.
Some, however, are looking at older theories including one from Fred Hoyle, who coined the term “Big Bang”, which claims the Universe has always existed and had no beginning.
“In the meantime, theorists have been busy dreaming up new physics that might solve the problem,” Dr. Matthews- wrote.
