Einstein’s theory of general relativity relies on the four fundamental forces found in the universe. Or so we thought.

Gravity, electromagnetic and strong and weak nuclear forces— is what our understanding of the universe revolves around. Einstein reportedly suggested that these forces stop planets, molecules and atoms from tearing apart while also serving as building blocks for the physical rules of cosmos. Researchers, however have discovered a fifth force of nature that may pretty much overthrow everything we know about how the universe works, reported Daily Mail.

“Einstein’s theory describes (gravity) beautifully well, but there’s a lot of evidence showing the theory has holes,” said team member Professor Andrea Ghez, director of the University of California, Los Angeles, Galactic Centre Group. “The mere existence of supermassive black holes tells us that our current theories of how the universe works are inadequate to explain what a black hole is,” she added.

The team made use of detailed images of the centre of the Milky Way captured by the Keck Observatory in Hawaii.

“By watching the stars move over 20 years using very precise measurements taken from Keck Observatory data, you can see and put constraints on how gravity works.”

Her research goes on to suggest that the gravity existing right in the middle of the supermassive black hole is so strong, that it indicates the presence of a fifth force.

“If gravitation is driven by something other than Einstein’s theory of General Relativity, you’ll see small variations in the orbital paths of the stars.”
