Currently we have:
1. Absolute time (AT) :
AT is the only time exist. The passage of absolute time is insensitive to motion or gravity. However, there is no clock time unit (including a clock second) that represents the same amount of AT in different frames. A clock second in the observer's frame will represent a specific intervall of absolute time. We use the LT to calculate the clock time value on a moving clock for a specific interval of absolute time (such as a clock second) on the observer's clock.
For example:
Delta(t')=gamma*delta(t)
This equation means that one second on the moving clock contains the same amount of AT as gamma seconds on the observer's clock.

2. Clock time:
A clock second on the rest frame of the clock will represent a specific interval of AT. A clock second in different frames will represent a different interval of AT. This means that a clock second is not a set interval of AT.

3. It is important that we accept the existence of AT. Why? Because all the processes of our universe are carried our on AT.

Interesting reflection on the nature of time.

Although I don't agree with everything.

I think that if we take the principle of covariance and refutation of any
absolute frame of reference, all the laws of physics are the same by
change of frame.

In particular, it is obvious that time also passes in the same way in all
frames of reference, since none is absolute, nor has priority over
another.

And anyone who contradicts would face a verbal inconsistency.

So, yes, time passes the same way everywhere. And we can take in
comparison, 100 men who are all 1.60m tall. They are all the same size. If
we move them relative to each other, they will still be the same size, but
their visual appearance will be different depending on how they move.

Those who will be furthest appearing the smallest, and vice versa.

I think that it is so with the nature of time, and that the only correct
time, the only real time, that I note Tr, is the time measured by the
subject himself.

All other times are observable times (To) by chronotropic effect; or
apparent times (Tapp) by chronotropic (gamma) and anisochronic effect
(cosine of the angle between the sight of the subject and the direction of
the mobile).

But it's not easy to talk about these things, the basics of which we are
only beginning to understand.

It is enough to see the enormous difficulties that certain posters show
when it is a question of simply understanding how a "Langevin" works, each
one believing to understand it, whereas only doctor Hachel really
succeeded in it, and that the others are still to the trail to understand
the notion of spatial reference mollusk and the elasticity of distances
and lengths.

Have a good evening.

Slow rate is real.... by strength of gravity and high speed.
