Wire Vs Wireless delay race.

  1. Jul 9, 2011 #1
    If we where to make a wireless phone call to a planet 1 light year away the lag/time delay would be 1 year.

    They would have to wait 1 year to hear what we say today.

    But if we used a long (long is an understatement) piece of wire connecting the 2 phones, what kind of delay would there be if any and why?

    Transmission along a wire would be slower. See: http://en.wikipedia.org/wiki/Wave_propagation_speed" [Broken]

    Information can never travel faster than the speed of light.

    I think energy is transmitted through the wire at the speed of greased lightning.
