How can the universe contain stars older than itself?
Riddle Me Thus.
From Mirror.co.uk :
‘A star that is “older than the universe” is baffling scientists, suggesting there might be something fundamentally wrong with the Big Bang theory.
Detailed measurements of the expansion rate of the universe, based on Einstein’s theory of General Relativity, place the Big Bang at around 13.8 billion years ago.
However, recent analysis of a star known as “Methuselah star” using the orbiting Hubble Space Telescope suggests that it is 14.5 billion years old – some 700 million years older than the universe.
The Methuselah star, code-named HD 140283, was first catalogued in 1912, and lies only 190 light years from Earth.
Another possible explanation for the discrepancy could be to do with “dark energy” – the mysterious force that acts as a counter to gravity.
Astronomers already think dark energy played a critical role in the Big Bang, but they have no idea where it came from.
“It’s a riddle of cosmic proportions: How can the universe contain stars older than itself?” Roberts wrote in an article for UAE-based media outlet The National .
“That’s the conundrum now facing astronomers trying to establish the age of the universe.”
