London, United Kingdom (4E) – A new study has again resurrected the theory that time did indeed exist before the Universe itself but in another Universe that gave birth to our own.
The study by University of Oxford physicists David Sloan, Tim A. Koslowski and Flavio Mercati suggests a completely new model of the Universe. Their published study re-interprets how time might have existed before the Big Bang itself by circumventing the limits imposed by the existence of the “Initial Singularity,” or that infinitesimally small blip that exploded to give birth to the Universe.
The model proposed by the three scientists starts with a new interpretation of the Initial Singularity.
The conventional wisdom is that physics as we know broke down inside the initial singularity. This breakdown arose from a contradiction in properties at a particular point in time as defined by the Theory of General Relativity.
Sloan, Koslowski and Mercati disagree with the assumption of an inevitable break down in physical laws inside the singularity. Instead, they adhere to the assumption that physics at the Big Bang remained intact but the stage it acted upon “reorientated.”
And instead of a singularity, the team said there is this thing called a “Janus Point.” In this Janus Point, the relative positions and scales of the stuff that comprise the Universe flatten into a two-dimensional (2D) pancake as we rewind time.
Passing through the Janus Point, that pancake turned 3D again, only back-to-front, so that time now moved forward. Sloan, Koslowski and Mercati believe their Janus Point could have profound implications on symmetry in particle physics, and might even produce a Universe based primarily on antimatter.
While the idea of a flipped Universe is nothing new, the model proposed by Sloan, Koslowski and Mercati of working around the singularity problem is novel.
“All the terms that are problematic turn out to be irrelevant when working out the behavior of quantities that determine how the Universe appears from the inside,” said Sloan.
“We introduce no new principles, and make no modifications to Einstein’s Theory of General Relativity — only of the interpretation that is put upon objects.”
