I read this on the usless facts gadget on my desktop. I'm not sure I understand it. Care to comment? A sunbeam setting out through space at the rate of 186,000 miles a second would go in a gigantic circle and return to its origins after about 200 billion years.
Sounds like a useless non-fact! --- On Thu, 12/23/10, sfisher01@comcast.net <sfisher01@comcast.net> wrote:

Thanks Joe, at least it is not "just me". I couldn't explain it.

We'll never see past the cosmic microwave background, much less see light from clear all the way around.

Isn't the second number roughly the number of years it takes the Milky Way to do a full rotation? I think that's the fact that they had in mind. ---- Rev. Michael A. van Opstall Department of Mathematics, University of Utah Office: JWB 313 opstall@math.utah.edu
A theory of Space-Time is that if you head out on a straight line you would eventually end up where you started. The Universe will bring you back to where your starting point. It is also why you can never get the "edge" of the universe to see what is on the other side, regardless of the direction you travel you will eventually end up where you began in about 200 billion years. So there is no beginning or end of the universe, no edge, no middle. The Universe is expanding but it is not expanding in anything. And as Einstein's theory says, space is curved although we don't see the curve, it looks straight to us but every straight line sooner or later ends up where it started. -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of sfisher01@comcast.net Sent: Thursday, December 23, 2010 1:12 PM To: utah-astronomy@mailman.xmission.com Subject: [Utah-astronomy] useless facts I read this on the usless facts gadget on my desktop.

The part I liked best was, "The Universe is expanding but it is not expanding in anything." How cool is that?
