A racer of 50Km/hr pigeons releases 1 bird every 5 min

someone's watch is responding to the motion and
the finite speed of the birds shouldn't be considered.

Not at all . when considering question of light propagation, you need to
take the speed that light travels into account.
So if we substitute light for the birds the watches will
go bonkers?

You might .. but I think I'll survive just fine.

What problem do you see when light is involved?

You are the one claiming that clocks get funny for
light but not for racing pigeons.

Actually I don't think you ever said the racer's watch
wasn't going slower to explain his wifes observations
so for all I know your sense of reality is as strange
as your maths.



But we were talking about clocks and lengths. Not about light
propagation.
The slowing of clocks and contracting of length as projected into another
relatively moving frame of reference is not some optical illusions due to
the speed the light is travelling. Even if you COULD instantaneously get
information about the lengths and clocks, you'd still end up with length
contraction and time dilation being 'seen'.

People get instantaneous information about clocks and rods
thousands of times a day.

No ..they don't .. you cannot get information faster then the speed of
light.

One station knows of the arrival of a code at another station
an ocean away, within 10 ns. That is only time for light
to propagte ~3 metres.

...well probably not on your side of the looking
glass where sentence precedes verdict.

Eh?

Are you as good with primary school maths as you are
with SR?

Yes .. equally proficient. SR is not really that difficult .. you should
try to understand it too .. you might get it one day.
I AM trying.

I'm glad. Keep it up. despite your off-topic posts, you are obviously and
intelligent person

If I can just figure out how the pigeon droppings get into
the racers watch to slow it, everything will be much clearer.
