Space trawl nets galactic result

Posted April 09, 2008 8:47 AM

From COSMOS magazine - News:

A ten-year star survey that found hundreds of thousands of galaxies has seen the project's Australian and British leaders lauded by a U.K. space conference. Their research led to a number of discoveries, including the first accurate calculation of the ratio of dark matter to 'normal' matter in the universe. Other key results included confirmation that the universe does not have enough matter for its gravity to rein in its continuing expansion, and that today's galaxies grew from tiny quantum density fluctuations in the early universe.

mapped more than 220,000 galaxies.

Out of the estimated 100 billion (give of take). Or a ratio of 10,000,000. to 22 (Think thats right). Quite an extrapolation. I'm not knocking the work it's orders of magnitude better but to say .000,002,2 percent tells us "this" is how it works. Makes me scratch my head. ( it's late, I don't feel good, and I hope the math is correct)

This should give us a better guesstimation of the probable number of galaxies.

Still far better than I could do.
