Stars Could Shine In Many Universes
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."
I dont read slashdot for 2 days and I missed the fact that there are more than 1 universes... shit!
That's funny, I always thought they came in herds.
Or maybe in packages - contents may have expanded during shipping.
"It's the height of ridiculousness to say for those 9 lines you get hundreds of millions."
Yes, the design is so good it works even if the 'constants' are way off. Convinces me, now I just need to work out which religion to sign up for!

I can't wait to meet the evil me and see how I look with a pointy beard.
Lay of the shrooms, maaaan.
Oh stop it. In a parallel universe, this makes perfect sense.

but what if i stick my head in the sand?

Only physicists can get away with this sort of crap. Any other field of science would be up in arms. Where is the falsifiability, asks Sir Karl Popper in his grave?

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!
Well, back to rejecting software patent applications.
I wonder if Adams found that the range of parameters would all result in the answer to the meaning of life in all universes being 42.
that the universe is truly just a 4 quadrant cube with 4- 24 hour days rotating simultaneously within 1- 24 hour rotation of a 4 quadrant created earth?
"all universes can support the existence of stars, provided that the definition of star is interpreted broadly"
hell yeah, in fact there's a 'star' right here on my desk
of course you must accept that my definition of 'star' looks remarkably like your definition of 'cup of coffee', but that's a minor point
But varying the other 16 produced hairy women, so he skipped them.
