We have two points A and B, separated by 10 light years away.
WE have an iron tube conecting the two points, so this tube its 10 light years long.
We are at point A and want to communicate with B, we have two options:
-move slightly the iron tube---> instantly the observer at B will receive the news
-send a light pulse---> we will need to wait for 10 years until B observes the light
Isn't the first method faster?
