Big Bang? What Big Bang? In a new theory, researchers suggest that the start of the universe may have involved no bang at all.

“Our theory suggests that the age of the universe could be infinite,” study co-author Saurya Das, a theoretical physicist at the University of Lethbridge in Alberta, Canada, told LiveScience.

In 1929, Edwin Hubble came to the conclusion that “there must have been an instant in time when the entire Universe was contained in a single point in space. The Universe must have been born in this single violent event.” This is what became known the Big Bang theory, NASA explains.

The formulation brings up two major points. First, that the universe possibly had no beginning which involved an infinitely small and infinitely dense point of matter. Second, that more information could be discovered on the make-up of dark matter. Dark matter is the substance that makes up most of the universe, and up until now has remained somewhat mysterious.
