BOSS: The Universe's Most Precise Measurement 128

Cazekiel writes "Observing the primordial sound waves created 30,000 years after the Big Bang, physicists on the Baryon Oscillation Spectroscopic Survey have determined our universe's most precise measurements: 13.5 billion years old. The article detailing the study reports: '"We've made precision measurements of the large-scale structure of the universe five to seven billion years ago — the best measure yet of the size of anything outside the Milky Way," says David Schlegel of the Physics Division at the U.S. Department of Energy's Lawrence Berkeley National Laboratory, BOSS's principal investigator. "We're pushing out to the distances when dark energy turned on, where we can start to do experiments to find out what's causing accelerating expansion."'"

    I'm sure that people who have studied cosmology, both theoretical and observational, in extreme depth, for a period of upwards of 20 years, are going to be devestated that "Proudrooster" and "decora" on Slashdot have shattered their entire field with a few brief sentences. Such a waste of man-hours! I'm sure the two of you will be quick to provide us with alternative models of cosmology and interpret them properly for the layman, causing no ambiguities in those who don't fully comprehend the fruits of your genius.

    Seriously, "a headline grab"? This is the ninth data release of a massive project that's been going for more than twenty years since it was first planned in detail, it's been studied by hundreds of extremely well qualified physicists, astronomers and engineers, and is providing data for all of us in the field to use to test models which we construct, from which we extract observable parameters, and test against observation... and you think it's a fucking headline grab? You think it's arrogant? The mind fucking boggles.

    It did say "precise" measurement afterall not "accurate." []

Did you hear that two rabbits escaped from the zoo and so far they have only recaptured 116 of them?
