A racer of 50Km/hr pigeons releases 1 bird every 5 min
from a 100Km/hr truck. His wife at the loft receives the
pigeons at intervals not of 5 min but
"a somewhat larger time" You are suggesting the
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?

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.

...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
