<p>This is something that has bugged me for a while:<p></p><div><br></div><div><span>Why can a photon only interfere with itself across multiple universes (interference), but can't interact with other photos in the same universe? i.e, why don't two photons interact when fired directly at each other?, and yet the same photon can interfere with itself across multiple universes?</span><br></div><div><span><br></span></div><div><span>Thanks,</span></div><div><span>Layman</span></div></p>
