The theory itself raises the very interesting
question “If time is just another dimension,
and everything moves forward, why it is not
possible to change the direction of time? “, in
other words, “Why cannot we travel back in
time?”
Even though this timeless universe theory is
still at the philosophical stage, some latest
quantum mechanical experiments have
suggested it can be right. Specifically, some
evidence has been found to back the fact that
the things we consider reality does not exist
until it is measured.
The current answer is,
Therefore, according to the way quantum

Timeless universe
At the beginning of the 1970s, quantum
physicists were faced with a common
problem. It was that the theory of relativity
does not always compatible with quantum
mechanics. John Wheeler and Bruce Dewitt
who were trying to unify them have devised
the Wheeler-DeWitt equation where time
had no value as a concept.
Later, a British scientist Julian Barbour
developed the concept further. According to
him, “There is no such thing as Time. Basically,
the universe is timeless.”
