Top 10 Weirdest Cosmology Theories

Stephen Battersby over at New Scientist SPACE has a nice little article on the weirdest of the weird in Cosmology.
  1. Clashing branes -- explains why our universe is a membrane floating in higher dimensional space, interacting with other universes via gravity.
  2. Evolving universes -- black holes create baby universes, and only those with the right conditions survive.
  3. Superfluid space-time -- postulates that space-time is actually a superfluid flowing with zero friction.
  4. Goldilocks universe -- is our universe special? Special in that out of an infinite number of possible universes, ours have the right properties to exist.
  5. Modified Newtonian dynamics -- reformulates gravity to make dark matter explain. Maybe we don't know everything about gravity after all.
  6. Cosmic ghost -- by adjusting Einstein's general theory of relativity, some strange substances pop into existence. Called the ghost condensate, it explains dark energy and dark matter.
  7. It's a small universe -- and it's shaped like a funnel, with a narrow end and a wider, flared out end like the shape of a trumpet.
  8. Fast light -- way back in time ... at the beginning of the universe, light used to travel a heck of a lot faster.
  9. Sterile neutrinos -- proposed to be dark matter.
  10. In the Matrix -- maybe our universe isn't really real, and we're all living in a simulation.

Civil disobedience is called for

Image
In an act of desperation, Tim DeCristopher chose civil disobedience to disrupt the bidding process that saw 149,000 acres of public land leased off to oil companies in Utah. The lease of the land to oil companies, to allow drilling, has been contested by many who wish to preserve the pristine land, located near Arches National Park, the White River, the greater Desolation Canyon region, Labyrinth Canyon, the benches east of Canyonlands National Park, Nine Mile Canyon, the Book Cliffs and the Deep Creek Mountains. It is one of the final sell-off by the dying Bush administration. DeCristopher showed at the auction, registered as a bidder, and started bidding -- and winning -- with no intention of purchasing or paying for the auctions he won. Way to go dude! You're a hero!
