    NASA’s WMAP is the Wilkinson Microwave Anisotropy Probe (which is a mouthful, and why we just call it WMAP). It was designed to map the Universe with exquisite precision, detecting microwaves coming from the most distant source there is: the cooling fireball of the Big Bang itself.

    WMAP Results

    A lot of this information was determined a while back, just a couple of years after WMAP launched. But now they have released the Five Year Data, a comprehensive analysis of what all that data means. Here’s a quick rundown:

    1) The age of the Universe is 13.73 billion years, plus or minus 120 million years. Some people might say it doesn’t look a day over 6000 years. They’re wrong.

    2) The image above shows the temperature difference between different parts of the sky. Red is hotter, blue is cooler. However, the difference is incredibly small: the entire temperature range from cold to hot is only 0.0002 degrees Celsius. The average temperature is 2.725 Kelvin, so you’re seeing temperatures from 2.7248 to 2.7252 Kelvins.

    3) The age of the Universe when recombination occurred was 375,938 years, +/- about 3100 years. Wow.

    Good to have even more knowledge about the universe.

    Do you ever look to what is peer reviewed? Credible? The best knowledge we have at a given time?

    Naaaaaaaaaah... why would you do that?

    How can relatively smooth, directionally uniform Wmap data be reconciled with the clumpy data of current observational astronomy? Mathematical physics seeks to provide answers:

    it is interesting informtion..but it is not absolute and subject to revision or even a profound reinterpretation of the conclusions,,,so... that it may be the best knowledge at a given time..is a fair statement, to represent it as indisputable fact.. case closed is not

    Science - as far as I know - treats all knowledge as tentative. I can't think of any scientific theory that was or is held as absolute and not subject to revision. That should reassure you, well as much as it can, coming from a non-scientist like me.
