[snip irrelevance]

Under SR, it is claimed that a clock
A at speed v >0 runs slower than a clock B at rest.

As observed by A, yes .. not as observed by B, and not as observed by
someone who sees oth A amd b moving at the same speed

So, SR claims that clock B runs slower when measured
from A's frame.

Yes

That's a sort of paradox, fella.

In the sense that it is not what one would expect withou understanding SR
(ie it is not an intuitive results) .. yes.

The
origin of that paradox is in the definition of time as
"that what clocks measure". Now, replace A and B
clocks by thermometers.

Why?

At initial conditions thermometers
A and B are in contact, displaying the same temperature
T_0, and the relative speed is v>0, but after a time t, they are a
distance r apart, and two synchronized relays were triggered
to heat both thermometers to T_1 > T_0 uniformly.

Ok

An observer
in A would see how thermometer B runs slower than thermometer
A, it is saying the rate of temperature change of B is slower than
that of A. But, an observer in B would see A running at slower rate
than that of B. It is clear that both thermometers are increasing
their
respective temperatures from T_0 to T_1, but seen from different
inertial frames the rates of change would be different.

Yes .. no problem there

Temperature and time are actually the same physical object.

No

The same way there is an absolute temperature 0 K , there is an
absolute time 0.

No

A clock at absolute temperature 0 K would be
observed running at a rate of 0 wrt any clock at a higher absolute
temperature.

A clock at 0k would indeed not run .. as any running of it would increase
its temperature above 0K

That's precisely the situation.

So what? If you pull out the batteries or forget to wind it, it will stop
as well.

If you pull out the batteries or forget to wind the clock, that's a
different
kind of stop. That's not the kind of stop I'm referring to. A clock
stopped,
because of no batteries powering it, is not a fair clock, it just
loses 1
second per second, but time is still running. I'm talking about ideal
clocks
(fair clocks).

Why?, Why would any running of
it increase its temperature above 0 K?.

Do you even know what temperature is?


Yes, I know what temperature is. If there is an energy flow between
two systems,
their respective temperature are equating to achieve a thermal
equilibrium. When
that thermal equilibrium occurs, then we can say their respective
temperatures
become the same and the energy flow stops.

The answer is easy, fella.

Yes .. motion causes temperature.

Yes .. motion causes temperature, but
temperature can cause motion, too. You only
have to heat a gas to see that.

Time and temperature are the same thing.

No .. that is complete and utter nonsense. Time is not temperature.

Correct, we all intuitively know that time is not temperature, but
IMHO both have to do with energy flows. It happens that SR
suggests me that maybe that what we call time dilation is the same
phenomenon as a thermodynamical state of a system observed from
a different inertial frame. Maybe I'm wrong, as usual :-),
anyway, I think it is an interesting possibilty.

Thanks for your attention
