Imagine you are one lightyear away from a photon sensitive (light sensitive) switch. So it is obvious that light would take one year to reach to the switch. Now I have a one lightyear long plank. I simply point the plank towards the switch and press it. Now I just did work which light would take 1 year to do in a matter of seconds.
Now the question is, did I break the laws of physics?
Please do not give an answer like " it is impossible to make a plank this long ". Just think about it. Even I am thinking about this question right now.
