Curious...

Photon travel at C, means that time is not ticking, so photon will never get old, decay, and will be immortal, eternity, is that true? but if we slow down photon (light), is the time starts to tick?<br /><br />Is Tachyon really exist? in antoher dimension? beacuse if it travel /> C, we will never be able to observe it, Tachyon has a negative time property?<br /><br />Thanks for any information, just curious. <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> </div>

Photons travel at c with respect all frames of reference except the photons frame of reference = not moving, so immortal, may never get old, nor decay, but not because of traveling at c.<br />Slow light likely is absorbed then re-emitted after a delay rather than traveling less than c. Neil
