Two teams of researchers have been studying the
flow of time in the universe. They have put forward the theory that the Big
Bang could have produced a second mirror Universe where the time flows in the
backward direction. The physicists proposed that the time flows in reverse
direction in that mirror Universe.

The physicist, Julian Barbour from the
University of Oxford in UK told “Time does not pre-exist. The direction and
flow of time we have to conclude from what is happening in the Universe. When
we consider it that way, it is predictable to say that time starts at the central
point and flows away in opposite directions.”

Physicists have been studying for decades over the fact that it is not vital for time to move forward. Lee Billings states that “Whether through Newton’s gravitation, Maxwell’s electrodynamics, Einstein’s special and general relativity or Quantum Mechanics, all the equations show that our Universe work precisely whether the time flows backward or forward.”

In 1927, a British astrophysicist Arthur
Eddington suggested that there exists an arrow of time. The second law of
thermodynamic states, in any isolated system such as universe, entropy keeps on
increasing. Our concept of Universe is that the Big Bang began with low entropy
and then everything moved toward high entropy. But this theory does not let the
time to move backward but the other laws of physics do.

Two more physicists, Sean Carroll from the
California Institute of Technology and Alan Guth from MIT (Massachusetts
Institute of Technology) used a different particle model and concluded the same
result. In this particle model, they produced a cloud of finite particles and
released it into an infinite Universe. They noticed the formation of 2
different arrows of time, one of them was directing toward the center where
there was low entropy and the other was heading toward increasing entropy.

Finally the whole cloud was spreading, giving
rise to entropy between them. Probably this central part with low entropy agrees
Big Bang, satisfying the concept of no beginning of time. Carroll and Guth have declared their findings
and documented that there are many drawbacks and still need to be corrected.
But with Barbour’s team’s joint study, it is worthy to say that there is
something else other than this single universe, which was created from the
beginning of time. However, I suppose that the Time Bat was correct.
