Hi, I have a question. If it were to turn out that the universe is curved, would it then be possible to use that information to find out how large the universe is? Similiar to how you could be shown a fraction of a circle, and be able to draw out, from the curvature presented, how large the entire circle is.

Just to show I'm not still grumpy, I also found these interesting sites:

http://www.astro.ubc.ca/people/scott....html#universe

http://background.uchicago.edu/~whu/...roduction.html

http://universe-review.ca/F02-cosmicbg.htm#universe

Hope someone else likes 'em.

Hi Kebsis

Scientists tell us their observations are that the universe is flat, within 2%, out to the light horizon, a diameter of 92 billion light years. So if anyone can do the math, that should set a lower bound on the curvature, and therefore the size, of the universe (for whatever curvature or topology you favor).

Sorry I can't do the math for you, I am but a humble motor mechanic...

Thank you, Steve Limpus, for your two comments. My responses follow:

Thank you for referring me to the multiple Internet references. I can appreciate that it took considerable work on your part to put that list and quoted material together. It'll take me some time to go through them, but I intend to do so in a timely manner Much thanks for your effort.
