The discovery has caused scientists something of a headache as it seemingly contradicts measurements we already have of the Cosmic Microwave Background, or in other words the ancient rumble of noise from the Big Bang.
Dr Adam Riess, from the Space Telescope Science Institute in the US, said: “This surprising finding may be an important clue to understanding those mysterious parts of the universe that make up 95% of everything and don’t emit light, such as dark energy, dark matter and dark radiation.”
The findings will appear in a forthcoming issue of The Astrophysical Journal.
One possible explanation could be a new type of subatomic particle that may have changed the balance of energy in the early universe, scientists believe.
The country launched its Dark Matter Particle Explore (DAMPE) satellite on December 17 and has finally started sending back information.
