Stars Could Shine In Many Universes

Posted by kdawson on from the light-of-other-days dept.

A commonplace of cosmologists who argue the anthropic principle is the assumption that if any or a few of the constants of nature took on an even slightly different value, life could not have evolved — perhaps even stars and galaxies would not form. Science News reports on a new calculation showing that, to the contrary, star formation could happen in up to one-quarter of universes with different values of three important constants. "In fact, all universes can support the existence of stars, provided that the definition of star is interpreted broadly," said the researcher, Fred Adams. "...calculations suggest that, contrary to some previous claims, stars are not only common in our cosmos but are also ablaze in myriad other universes, where the laws of physics may be drastically different... Had Adams found that the range of parameters that allowed for stars was very small, that would have suggested that the laws of physics in our universe have been 'fine-tuned' to allow for star formation... Instead, Adams' study shows that our universe doesn't seem particularly special in that regard."

      When I was small and liked to make shit up, I designed "flyingpigs theory" which has 1,235.656565 universes. So there. It's string theory, but with a more realistic name and a bigger number (so it must be better right?).

      there's a difference between theory and hypothesis.

      one has a grounding in reality, one can be made up by 10 year-olds and still be 'valid'

      guess which yours is

      yeah but in another universe he trounced MightyMartian with the ultimate comeback, and MM flew back to Mars to cry to his mama!

    i thought "uni" meant one and only.

    doesn't "uni" mean one and only?

    Which is why I find your double post so delightfully ironic!

    Considering Paris Hilton is famous for being basically nothing more than a rich party girl, and given the popularity of Youtube these days, I bet even a feces throwing monkey could become a star in OUR universe.
