Vibration in space

  1. Feb 4, 2010 #1
    Say someone hits an iron block in space with a metal hammer, causing vibration.

    Will vibrations in space keep vibrating forever?

    To my understanding vibrations stop vibrating on Earth because the object vibrating sends the energy into the air which takes that energy away from it. Since there isn't any air in space to take the energy away will the object vibrating vibrate forever?

    My physics teacher said that eventually the vibration will make the iron block heat up and eventually start giving off photons of heat but he wasn't 100% sure of this answer.
    Please help.
