This Crazy Old Star Is Challenging The Big Bang Theory!
Age of the Universe
Dating the Big Bang has always been of paramount importance among the scientific community. Astronomers determined the age of the universe using a combination of observations and scientific calculations.
Age of stars
Now, I know stars are some balls of gas that shine in the universe, burning elements and fusing them into heavier ones, as time passes by.
The Methuselah star, also known by the very boring name “HD 140283”, has been the subject of significant interest and debate regarding its age estimation over the years. Everything started in 1912 when it was first cataloged. Astronomers from the Mount Wilson observatory noted it lay only.
It’s important to note that estimating the age of stars can be a complex process, and various factors like uncertainties in stellar models and measurements can contribute to discrepancies.
In 2013, scientists thought Methuselah might be older than the whole universe!
Population I, II,III
So, where do these uncertainties come from exactly?
It’s about the measurements from the ground. You should not forget that we can only get the age of a star by taking measurements.
The Importance of Better Estimates
The story of Methuselah stresses the importance of having updated measurements, made with different instruments and using different approaches.
