Is comunication faster that light possible: yes( maybe )

  1. May 31, 2015 #1
    i think it is possible but its too complicated to write down in english so i think comunication faster than light is possible without anything acctualy moving faster than light. If you had a big stick between earth and the sun and you push the stick towards the sun for 1 inch it will instantly move at the other side too. for light to come from sun it takes 7 min and for this to move at the other side after you push it on your side nothing.look at the image so you can get a better understanding.

    No. You're not taking into account the electromagnetic forces that hold the stick together. The other end won't move faster than the speed of light.
