It's akin to a 100 foot long tube of marbles.
Hit one end of the tube with a hammer and
measure the time it takes the energy impulse
to reach the other end of the tube. How fast
and how far did the energy impulse travel?
How fast and how far did each marble travel?

Absolutely. When the old lady in the flat below bangs on her ceiling with
her walking stick, the end of the stick hits the ceiling instantly as she
pushes it upwards. Extrapolating, if an incompressible/inextensible rod or
string could be made, wouldn't that permit communication faster than the
speed of light?

I guess inextensible and incompressible are difficult to achieve, but if
either were possible would the communication still be limited to the speed
of light?
