A compass and scale image of the Borg 58 galaxy field, showing five tiny galaxies clustered together 13.1 billion light-years away, is seen in this January 10, 2012 handout. The circles pinpoint the galaxies. Astronomers uncovered the cluster, the most distant such grouping ever observed in the early universe, using NASA's Hubble Space Telescope. The sharp-eyed Wide Field Camera 3 aboard NASA's Hubble Space Telescope spied the galaxies in a random sky survey. The young galaxies lived just 600 million years after the universe's birth in the big bang. Reuters

A new theory has been proposed by Dr Julian Barbour of College Farm, Dr Tim Koslowski of the University of New Brunswick and Dr Flavio Mercati of the Perimeter Institute for Theoretical Physics. The researchers said that a "mirror universe" was created to the universe, during the Big Bang and that not one but two universes were created at that time, both of which moved equally in direction but opposite to each other.

According to the Daily Mail, the theory might help answer questions related to the beginning of time and the past. The research was an attempt to answer question relating to the "arrow of time," a concept that time time was "symmetric" and that everything moved only in the forward direction.

The "mirror universe" theory suggested that it moved backwards through time. They added that through time, the intelligent beings in one universe could perceive the other to be moving in the opposite direction.

A model was assembled with 1,000 particles to prove the theory. The researchers said that their theory showed that when one moves backwards through time to disorder, one would come out to the other side that was in order again and which was a "mirror universe."

Barbour said that time was a mystery and that all the known laws of physics looked the same irrespective of the way that time ran. He added that in the world, everything goes only in one direction.

He gave an example of the melting of an ice cube in a glass of water and compared it to the universe which moved from structure to disorder. He said that the universe was expanding and that everyone got older and the order seemed to grow, in the immediate vicinity. He spoke about how people, at the end of the 19th century, thought that the universe would end in a "heat death" where the temperatures in the universe was the same everywhere.

When gravity was taken into consideration, the "mirror universe" did not hold true. Lee Billings wrote that the sheer force of gravity resulted in setting the stage for the expansion of the system as well as the origin of the arrow of time.
