Astronomers using the giant 10 meter Keck telescope have made the most precise measurement to date of the amount of deuterium, or heavy hydrogen, in the universe. This finding provides a stringent constraint on the Big Bang theory for the origin of the universe. Led by David Tytler of the University of California, San Diego, a team of six astronomers observed absorption lines in light from a quasar. Specific wavelengths of the quasar light were absorbed by various types of atoms in an intervening, and very distant intergalactic cloud. They determined that the cloud contained about one deuterium atom for every 40,000 normal hydrogen atoms. This number, which is consistent with other independent measurements, gives the team confidence that they and other scientists are closing in on one of the most important pieces of evidence for proving the Big Bang theory. "According to the theory, primordial deuterium was created by nuclear reactions in the first one thousand seconds of the Big Bang," explained Tytler. "The amount depends sensitively on the number of protons and neutrons present, so if we measure the deuterium, we can determine how many protons, and therefore how much matter is present in the universe." The team involved in this research also included David Kirkman, Nao Suzuki, Dan Lubin and Arthur Wolfe of UCSD's Center for Astrophysics and Space Sciences, and Jason Prochaska of the Observatories of the Carnegie Institute of Washington. Some of the observations were also made with the Shane 3 meter telescope at the Lick Observatory.

For some reason the elites - social/financial/church don't want people to know the Universe is expanding forever and that we're all on "the Long Journey" ------------------------------------------------ FURTHER REFERENCES GO - "search perceptions" - in SEARCH-ENGINE file-ID www.perceptions.couk.com/uef/waffle.txt
