<table border='0' align='center' width='95%' ><tr><td class='quotetop'>Quote: (Octan @ Oct 19 2004, 06:55 PM)</td></tr><tr><td class='quotebody'> I don't get the whole "universe is expanding" thing. They say they know it's expanding because they see stars as having "red shift," but if they don't know how red the stars are to begin with, how do they know how much red shift there is??? Scientist: We know there's red shift because the stars appear redder than they ought to be. Me: How do we know how red they ought to be? Scientist: By taking how red they are and then adjusting for red shift. <img src='http://definecynical.mancubus.net/forum ... iggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif' />  </td></tr></table>  And to answer the other part of your question, the objects in the universe are getting farther apart, and this is happening (assuming the scientists are right) at an accelerating rate.

I have a theory It is just to be contraversial but it was inspired by Homer Simpson. The Universe is Doughnut shaped Hear me out on this one guys, then bombard me with the scientific disproving: There is a giant black hole in the middle of the universe. It is connected to another equally big one. When I say Big I mean BIG; the two together are the height of the univese. These keep the univese in constant motion and so it is not so much expanding as going around and around. It may even spin a little, who am I to say? Perhaps the black holes have spin but they cancel out. I don't know. I'm gonna do a sketch cos I'm not bein too clear. And Restecp to VisiMisi on the Red Shift stuff.

And, doughnuts are the food of the gods . . . MMM . . . doughnuts . . . But, by this theory we probably would see a red shift in the stars in one direction and a blue shift in another. This would also lead to some interesting ideas about interstellar travel.
