Canceling photon momentum

  1. Feb 18, 2004 #1
    if two photons are cancelling , does the resultant exist ?
    For example if there are two laser beams exactly cancelling in space, the result is no doubt invisible, but does the "beam" exert momentum, gravitational bending etc?

    There are two laser beams exactly cancelling everywhere in space and in every direction that there is no laser light. No momentum (impulse) or gravitation has come of it to my knowledge.
