| Summary: | According to the American Heritage Dictionary of the English Language the definition of time
involves the continuity of existence in a sequential way from the past, through the present, into
the future. Just imagine if the universe were completely static, there would be no what so-called
time and no the existence of the matter. The existence of time appears just because things
change [1]. The story of time began from the creation of the universe through the history of
modern human life in the form of the fourth dimension (one temporal dimension along with
another three spatial dimensions, or up to twenty-six dimensions according to the string theories
[2].
Prior to 1900, time was considered to be uniform and the same everywhere in the universe
where the observers measured the same time interval for any event, which departs from the
classical physics of the Newtonian era. This concept stands undeniably for everyday motions on
Earth as an accurate approximation at velocities lower than the speed of light. In 1905, Albert
Einstein proposed his postulates in special relativity, where Newtonian mechanics could not
agree with Maxwell’s equation of electromagnetism [3, 4]. He shared his view about the problem
of the classical understanding of time, in the context of electricity and magnetism, which can be
resolved by invoking a method of synchronizing clocks using the constant speed of light in a
vacuum as the maximum signal velocity.
