Time

Time is that immaterial entity which controls our lives. It can make our lives short or long, but actually it only goes by, with its inexorable passage. What is more, our minds adapt themselves for our pace of life which is like a mill wheel or like a succession of cogwheels according to some ancient civilizations.

However, having grounds for theory of physics by Albert Einstein, the speed of the light is a universal constant, in other words it doesn’t depend on the system of reference, it is absolute and any other magnitude can change its value depending on the system of reference.

Taking several equalities and being ‘c’ the speed of the light and ‘v’ the speed of the system of reference, we get this equalities for length and mass:

Length l’ = l √ (1-v²/c²)

Mass m’ = m / √ (1-v²/c²)

And using the transformation of Lorentz, and so on we get the following equality for the time, having x values of length:

Time t’ = (t - vx/c²)/ √ (1-v²/c²)

Oversimplifying, apart from physics considerations, time is not absolute according to the theory of the physics. Fortunately or unfortunately, we cannot notice it every day because we would need to travel with a speed in the order of speed of light.

In my opinion, it’s true that time seems to slow down when we do activities that we don’t like and it flies when we are enjoying with something, but this is only an effect of our own mind.

To sum up, more research needs to be done and more theories as ‘strings theory’ must be developed, and great minds like Einstein, Hawking, Susskind, Written or Lanza are necessary, in order to find the ultimate true about time. That is why we don’t even know the one per cent of all that we could know; therefore human being has a long, hard and amazing task ahead.
