• A Quest for a Theory of Everything - Physics
    Physics is the foundation for a Theory of Everything. ToeQuest is a science-based website and emphasizes a scientific approach to theory development. Although we venture to the fringe of science, and maybe a step or two beyond, we avoid the crackpot arena. We seek out individuals with a great ideas who are willing to share, explore, and help others.

  • Dark Matter -- "The Tip of an Iceberg of Another World Unrelated to Ours"

    dailygalaxy.com -- Answering the observation that the dark matter particle might not be detectable at a colloquium organized by the Kavli Institute for Cosmological Physics at the University of Chicago, Michael Turner, a theoretical cosmologist trained in both particle physics and astrophysics who coined the term “dark energy,” said that for 20 to 30 years, this idea that dark matter is part of a unified theory has been our Holy Grail and has led to the WIMP hypothesis and the belief that the dark matter particle is detectable. "But there’s a new generation of physicists that is saying, 'Well, there's an alternative view. Dark matter is actually just the tip of an iceberg of another world that is unrelated to our world. And I cannot even tell you about that world. There are no rules for that other world, at least that we know of yet.

    "Ten years ago," Turner says, "I don't think you would've found astronomers, cosmologists, and particle physicists all agreeing that dark matter was really important. And now, they do. And all of them believe we can solve the problem soon. It's wonderful listening to particle physicists explain the evidence for dark matter, and vice versa –astronomers explaining WIMPs as dark matter."

    "As cosmologists," said Rocky Kolb, who studies the application of elementary-particle physics to the very early Universe, and is the co-author with Michael Turner of The Early Universe, the standard textbook on particle physics and cosmology, "one of our jobs is to understand what the universe is made of. To a good approximation, the galaxies and other structures we see in the universe are made predominantly of dark matter. We have concluded this from a tremendous body of evidence, and now we need to discover what exactly is dark matter. The excitement now is that we are closing in on an answer, and only once in the history of humans will someone discover it."

      Thanks Robert for this most interesting post,I think dark matter is really just etheric matter slightly out of phase with the physical universe and thereby almost undetectable,but we can see its "wake" and thats what all the excitement is about.

      regards michael.
