Talk:Light-year


 * Can we percieve a light year with a chronological history or is it some protruse formation of gamma, photon, and light measured by rad per planet and then divided by the sun and the graph of fixed light on paper causing a motion of time or is it the aging process and quick maturation of cell activity in radioactivity.--Abbeyhuling
 * I think you should read the definition again. That explains what a light year is simply enough. A light year isn't just restricted to the distance that light travels in one year though as radio waves, X-rays, gamma rays, UV and infra-red (or anything else on the EM spectrum) all travel at the same speed, therefore covering a fixed distance in the same amount of time.--Scimitar 21:53, 18 Jun 2005 (UTC)
