TIME IS NOT RELATIVE
N. Joica
[email protected]
In Relativity, mistakenly, the time passes slower for the observer who is in motion
relative to a reference frame, no matter if the observer is moving closer of farther apart from
the observer at rest.
An observer at rest would calculate time for the observer in motion as:
1
∆t '
∆t = ∆t '∗α = ∆t ∗
=
2
v
v2
1− 2
1− 2
c

In relation (1) there are two mistakes:
I.We cannot calculate the way in which time passes for the observer who is moving.
We can calculate only the way in which the passage of time is perceived (seen) by him.
II. We can calculate the way in which) the passage of time is perceived (seen) for the
observer who is moving only in the case in which he is moving away from the one at rest,
because in his (alpha = constant of proportionality) calculation, WAS PLACED THE
CONDITION THAT THE OBSERVER IN MOTION IS MOVING AWAY FROM THE
ONE AT REST.
In order to be used to express the way in which the passage of time is perceived for the
moving observer regardless of the direction of his movement, alpha has the next relationship:
1
α=
v2
1 − cos β ∗ 2
c
(2)
Where beta = the angle of observation. According to (2), we can see that as the moving
observer approaches the one at rest, β∈(PI/2;3PI/2), the observer at rest ‘sees’ the time of the
one who is moving pass faster, and if the moving observer recedes, β∈(3PI/2; 0)∪[0; PI/2),
the observer at rest ‘sees’ the moving observer’s time pass slower.
In the case where beta=PI we have:
1
∆t = ∆t '∗α = ∆t ∗
1 − cos(PI )

We have a special case when beta=PI/2 or beta=3 PI/2

CONCLUSION
Relations (1) and (2) do not tell us how time flows for the moving observer, but only
for the fixed observer. (Understanding this optical illusion, indicates we should be more careful
in our assumptions. For example, a star sends out light with a constant frequency. Depending
on the direction of movement, we observe that when the star is moving away, the light will
suffer a displacement towards the red end of the spectrum (the frequency of light is geting
smaller). When the star is geting closer, light will be displaced towards the violet (the
frequency of the light is growing). According to this example, we can say that if the frequency
of the light that we took as a standard unit of time varies with the direction of relative motion.
OBSERVATION
In the same way we can demonstrate that in every relation in which we have to use
alpha, it must be replaced with the general relation (2) and then we can calculate how the
measurements will be perceived from the inertial system at rest. An exception to this rule might
be when trying to express the height. It is possible that the height may vary with speed
considering the ether as an absolute fixed reference frame.
