Light from the Past


When you stand and look at the stars, you are really looking at past history. The light from Alkaid, the end star in the handle of the Big Dipper, has taken about 210 years to __reach__ your eyes. If Alkaid stopped __shining__ today, people on earth would still see it __for__ about 210 years. Some of the stars you see here tonight may have stopped existing several thousand years ago. The light from some __faraway__ stars right now will not be seen on earth until thousands, or even millions, of years from now!

But light waves stop only if they strike something, and their energy is transferred __into__ another form. __Otherwise__, they can go on and on, at the same terrific speed, with no loss of energy, forever!
