So how old is the Universe anyway?
If you have ever watched Doctor Who, Star Trek, or any science fiction programme, you must have come across this theory of the age of our Universe. Well now, the astrophysicists have calculated the exact age of the Universe… mostly.
The universe is about 13.8 billion years old, according to new research recently published by an international team of astrophysicists.
The oldest light!
The scientists studied an image of the oldest light in the universe to confirm its age of 13.8 billion years.
This light, the “afterglow” of the Big Bang, is known as the cosmic microwave background and marks a time 380,000 years after the universe’s birth when protons and electrons joined to form the first atoms.
Obtaining the best image of the infant universe helps scientists better understand the origins of the universe, how we got to where we are on Earth, where we are going, how the universe may end and when that ending may occur.
The new research adds a fresh twist to an ongoing debate in the astrophysics community about the age of the universe.
Did you know
While this estimate of the age of the universe had been known before, in recent years, other scientific measurements had suggested instead that the universe may be hundreds of millions of years younger than this.
