What we don’t know about the Universe… could fill the Universe. Two theoretical physicists have suggested nothing like the Big Bang a role in the of our universe 13.8 years ago, refuting Edwin Hubble’ 1929 theory that the universe was contained in a single point in space and some violent event caused it to expand.

“Our theory suggests that the age of the universe could be infinite,” co-author Saurya Das, a theoretical physicist at the University of Lethbridge in Alberta, Canada, LiveScience.
The study denies claims of an infinitely small and dense point of matter being in the beginning of the Universe, as stated in the Big Bang Theory.

“So when we say that the universe begins with a big bang, we really have no right to say that,” Robert Brandenberger, a theoretical cosmetologist at McGill University in Montreal told LiveScience.

The Big Bang theory comes from Einstein’s general theory of relativity.

The two scientists looked at the two dominant physics theories, quantum mechanics and general relativity, and concluded that they cannot be reconciled as they both fail to dark matter.

So they decided to regroup, and found “holes in Einstein’s theory.”
way to test the theory is to look at how dark matter is in the universe and see if it matches the properties of the proposed superfluid… If our results match with those, even approximately, that’s great,” Das said.

Both scientists confirm that the universe was once very small and hot, but agree that it is infinitely old.
