Parallel Universe Theory...Comments? Concerns? Questions?

Extract: New research suggests our Universe could be moving forwards in time, while a parallel one moves backwards on the “other side” of the Big Bang.

Physicists have performed an experiment that suggests time in our Universe may be directed by gravity, not thermodynamics, and that the Big Bang could have created two parallel universes - our own, in which time runs forwards, and a mirror one where time runs backwards.

Although the idea sounds pretty out there, the new theory could help physicists solve some of their biggest issues with time - mainly the fact that they still can’t work out why it runs in only one direction.

In fact, this single “arrow of time” is one of the biggest conceptual problems of modern physics and has puzzled physicists for more than a century.
The root of the dilemma is the fact that all of the fundamental laws of physics - such as Einstein’s special and general relativity and Newton’s gravitation - work just as well if time is flowing forwards or backwards.

In models of physical systems, which physicists use to mimic our Universe, a preferred direction of time does sometimes arise, but this typically only happens when researchers tinker with the system and set specific starting conditions.
