Here is an important article to read about significant new discoveries related to the "Big Bang" and expansion of the Universe:
http://www.princeton.edu/pr/pwb/03/0217/
"In August 2006, using NASA's Chandra X-ray Observatory, a team from NASA's Marshall Space Flight Center (MSFC) found the Hubble constant to be 77 kilometers per second per megaparsec (a megaparsec is equal to 3.26 million light years), with an uncertainty of about 15%. [3]" Wikipedia

Hubble constant, a number which represents the expansion rate of the Universe.
Its value is:
71 +/- 3.5 km/sec/Mpc

http://en.wikipedia.org/wiki/Hubble's_law
"As of the 2006 data, that figure has been refined to 70 +/- 2.4−3.2
(km/s)/Mpc."
This, of course, is what we THINK the expansion rate is, given our current technology and knowledge (and current assumptions on the age of universe). And, of course, assuming that the universe IS expanding.
