| Fredi; let us analyse this problem a bit more rationally and
| rigorously.
| You say that now does not exist and that all what matters is the time
| interval.
| Why are they contradictory in your mind!
| Didn't you know that now is an interval!
|
| Tell me the name of THIS century?
| Tell me the name of THIS year?
| What is the name of today?
| Etcetera.
|
| Notice that today is neither tomorrow nor yesterday.
| If tomorrow is a future time and yesterday is a past time then what is
| today?
|
| This hour, this minute and this second are all now(s).
|
| This femto-second is certainly a higher resolution interval that could
| be seen as a point on a macro-scale.
|
| Time is an absolute continuum and points in time are imaginary
| constructs made by the human mind to represent time limits on a
| geometric scale to represent time intervals' magnitudes.
|
| An abstract construct is to reverse the psychological conception of
| time such that we imagine time to flow through us at a point called
| now rather than us living through static time as a continuously moving
| point.
|
| Indeed, absolute time is not static and that is why we cannot move
| back in time because we are not moving at all in time.
| It is time that is flowing from future to past through our perception.
| The extents are infinite and that is why subtracting from the future
| and adding to the past does not make any difference.
|
| To understand why a specialist of the human brain's biochemistry like
| me insists that now must be an interval, I should explain to you the
| human perceptual mechanics in which a quantum of the mental
| observation time must be an interval also. Chemical reactions do not
| happen in time points but they happen in periods or intervals because
| they do involve spatial transitions of chemicals to undergo a reaction
| at some tenable velocity over some time interval; hence "now" must be
| an interval and not a point in time.
If you want to define a "now" as an interval, then how long is the interval
for a "now"?
[EL]
You ignored all the examples I gave you and still asking a meaningless
question.
You are always experiencing "now" Fredi.
You never experience the future even though you may think about it
"now" but never experience that future until that future comes.
You never experience the past even though you may remember that you
have once experienced it when it was the "now".
Now you are reading my post.
I wrote this sentence now but every now is different from every other
now.
We may shake hands and say in one voice "We are shaking hands now".
So "shaking hands" takes time during which we may call it "now" of
when we said it.
How long does it take to shake hands!
As long as it takes Fredi.
<snip>
I just don't believe in absolute time or space.
[EL]
This is fine Fredi; you do not need to believe.
Ask yourself what is the meaning of Galilean, Lorentz, SR and GR
transformations.
What happens when frames of reference are unified by transforming one
into the other?
If you fail to make a logical connection between two events and call
them simultaneous you fail to compare velocities and dates.
What is the meaning of the statement "I was born on the same day on
which Einstein died"?
How long did my birth take and did it start already when my head is
out in the air or not and is it ended yet before my feet were out; of
course not. Ask any delivery nurse about the standard average time
interval of a birth operation if you insist to know how long is "now"
during which it took place. But simultaneity is more flexible than you
think as I have demonstrated.
There is a separate-time-simultaneity like having breakfast and lunch
and dinner on one and the same day.
There is also an overlapping-time-simultaneity like reading a
newspaper while eating breakfast. You may start either of the two
tasks first and then the other and you may end either of the two tasks
first and then the other, but you are sure that you have spent some
time reading while eating and eating while reading.
There is also a contained-time-simultaneity such as hearing the
doorbell ringing while watching television, in which watching is a
longer task that encapsulates the ringing.
There is also an-almost-coincident-simultaneity in which
(statistically) more than 99% of each of two tasks' time intervals is
concurrent to the other. Hence if two tasks had exactly the same time
interval magnitude, it is impossible to empirically confirm the
absolute coincidence of the limits. And that is why real science must
have error margins and tolerance and significance and precision.
<snip>
There is no absolute time "flow".

You are simply wrong because every thing I explained here in this post
is evidence of the opposite.
If relativists did not understand that a universal absolute time flow
must exist then what are they relating and to what end? There would be
no need for any relativity to find the correct places of the pieces of
the puzzle.
When two Time Windows overlap, there is a common time interval between
them.
If we fail to find a Time Window with common intervals with other
being-related-two-intervals it is impossible to tell which of those
two happened first.
All the events, within the universe, which share a common time
interval, form a universal absolute Time Frame limited by that common
time interval of all the universal events that share a common time
interval.
Our task as scientists is not to assume it or believe in it pr predict
it but to prove it and find it.
What else would relativity be about?
