In 1932, when they began studying how stars behaved within galaxies, astronomers found too few stars to account for the gravitational pull necessary to keep a galaxy together. Something unseen--termed " dark matter " --had to account for the missing mass, and there had to be a lot of it. Most experts now estimate that 90 percent of the universe is comprised of this elusive stuff. " Dark matter " has escaped detection because it does not emit enough electromagnetic radiation--perhaps none at all. At first, scientists inferred its existence by measuring its gravitational effects on nearby stars and galaxies. But in 2000, scientists found evidence of " cosmological shear, " a phenomenon in which light from distant objects bends under matter's gravitational pull. Dark matter may be dying stars, brown dwarfs (objects nearly as large as stars), or vast clouds of neutrinos--fundamental particles that are very difficult to detect. One of the strongest candidates is the hypothetical WIMP, or Weakly Interacting Massive Particle, perhaps 50 times heavier than a proton. Once dark matter is identified, the task of determining how much exists would begin. Some scientists believe there may not be enough dark matter to halt the universe's ever-accelerating expansion, and as stars burn off their fuel (in about 10 trillion years), the universe will grow cold and dark. Conversely, there may be enough dark matter to tip gravity's scales, and start the universe on the road toward a " Big Crunch " --in about 50 billion years--with everything contracting back into a cosmic singularity similar to how the universe started. Were a Big Crunch to occur, the resulting singularity could produce another Big Bang. This hypothesis--of a universe that oscillates between expansion and contraction--mirrors the creation myths found in Hinduism's ancient Puranic texts. Perhaps their anonymous authors, who presciently placed the age of the universe in the billions of years, knew somethings we do not. _______________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx Quote Link to comment Share on other sites More sharing options...

It brings home some of the very interesting findings of Modern Physics. We live in exciting times, the findings of Physics are the greatest ally of the ancient philosophies of Hinduism. Not Puranic tales - the philosophies like Samkhya and Vedanta are closer to the mark, but I do not think any of these Physicists are aware of this. Surely, we will make them aware... : ) jay Quote Link to comment Share on other sites More sharing options...
