Assume a stick of length 15*3*10^8 metre. One end points towards me, at the other end we place a ball very near to the end of the stick. If i push the end pointing towards me with some force, instantaneously the ball will be moved(~). At the same time, a light beam emanating alongside me would take 15 seconds to reach that ball. How can i change the information of a space even before the light beam reaches out to that place (~)? This question appears to be childish, pardon my innocence, explain me please. I've been baffled by this question since my childhood. I know this question is a flaw or immature way of understanding a concept, please find out the misconception I've been thinking of. P.S: I'm NOT gonna SHAKE, or BANG, or MAKE VIBRATE the stick. This situation is slightly analogous to newton's gravity model which contradicts with light's speed limit later overturned by einstein's general theory of relativity, but not completely i think. (~)-Doubtful.
