1. The time

2. Traditionally, time is seen as a form of measuring
the distance between events.
It is composed of past, present and future. The
past is regarded as something which already
happened that cannot be changed. The future,
however, is regarded as a multitude of possibilities
available.
People measure time using several units, some
based on real events (the rotation of the Earth around

3. The classic description of time made by Isaac
Newton
in his "Principia" is that time "flows" constantly,
the same for all.
I mean it is independent of events that occur within it.
This time description was eliminated by Einstein and his
theory.

4. The classic definition of time is based on the way people
perceive its "passing".
We acknowledge events from a personal point of view
and we assume that this is what it is like everywhere.
The classical approach to time does not explain why we
perceive time in this way and not how this effect is
acquired.
Other theories about the nature of time question the
"roots" of this natural point of view.

5. Time accompanies us everywhere,
reminding us of the uniqueness of each moment of
our passing through the Universe.
What is time in its essence?
Was Einstein right when he said that time is
relative?

6. Time is the anonymous that slides between our fingers,
taking with it our whole existence.
Everyone knows what time is because it can be seen
passing.
This is probably the first characteristic of human
experience.

7. Maybe that is why clocks have been invented - the scientific
mode to measure time objectively,
outside our personal experiences.
A few houndred years ago,
people supposed that time and space were simply given by
God.
Saint Augustin from Hippo noticed that
”the attempt of defining time is basically just a lining of words
that are going to get lost without accomplishing a portait of

8. The demonstration of Albert Einstein
which says that that time is relative,
was a real shock for the scientific community and for the
religious one.
Shortly and for everyone’s capacity of understanding,
the essence of the theory is that
”my time is not the same as yours if we are moving
differently” .

12. Philosophers and physicists have been
researching for thousands of years if the passing
of time is a physical effect or an illusion.

13. What is for sure is that in physics there is
nothing that matches a flow or a movement of
time.
Some may say that even if the past or the future
do not have an universal meaning,
it surely exist a distinction in time between the
direction to the past and the direction to the
future.
