Am I the only person in the world who had never heard of this before last night?
The Wilkinson Microwave Anisotropy Probe (WMAP) is a NASA Explorer mission that launched June 2001 to make fundamental measurements of cosmology -- the study of the properties of our universe as a whole. WMAP has been stunningly successful, producing our new Standard Model of Cosmology. WMAP continues to collect high quality scientific data.
- NASA's Wilkinson Microwave Anisotropy Probe (WMAP) has mapped the Cosmic Microwave Background (CMB) radiation (the oldest light in the universe) and produced the first fine-resolution (0.2 degree) full-sky map of the microwave sky
- WMAP definitively determined the age of the universe to be 13.73 billion years old to within 1% (0.12 billion years) -
- WMAP nailed down the curvature of space to within 1% of "flat" Euclidean, improving on the precision of previous award-winning measurements by over an order of magnitude
- The CMB became the "premier baryometer" of the universe with WMAP's precision determination that ordinary atoms (also called baryons) make up only 4.6% of the universe (to within 0.1%)
- WMAP's complete census of the universe finds that dark matter (not made up of atoms) make up 23.3% (to within 1.3%)
- WMAP's accuracy and precision determined that dark energy makes up 72.1% of the universe (to within 1.5%), causing the expansion rate of the universe to speed up. - "Lingering doubts about the existence of dark energy and the composition of the universe dissolved when the WMAP satellite took the most detailed picture ever of the cosmic microwave background (CMB)."
- WMAP has mapped the polarization of the microwave radiation over the full sky and discovered that the universe was reionized earlier than previously believed. - "WMAP scores on large-scale structure. By measuring the polarization in the CMB it is possible to look at the amplitude of the fluctuations of density in the universe that produced the first galaxies. That is a real breakthrough in our understanding of the origin of structure."
- WMAP has started to sort through the possibilities of what transpired in the first trillionth of a trillionth of a second, ruling out well-known textbook models for the first time.
- The statistical properties of the CMB fluctuations measured by WMAP appear "random"; however, there are several hints of possible deviations from simple randomness that are still being assessed. Significant deviations would be a very important signature of new physics in the early universe.
- Since 2000, the three most highly cited papers in all of physics and astronomy are WMAP scientific papers.
What the fuck? Shouldn't this have been a bigger deal the past few years? I realize I spend too much time with my nose stuck in my Sweet Valley High VHS tapes, but you'd think this would've made enough of a splash to break through to even me. Shit's amazing.
NASA's like an umpire; we hear about the fuckups/tragedies, but never when they do their job ridiculously well. What the fuck. We love to wander around romantically wondering "why are we here?", but when someone moves towards actually knowing the answer we're not interested in hearing about it I guess.
Also, does NASA actually have a sense of humor, giving it an acronym to look like a radio station call sign? I also don't know why NASA would be so excited about making the Guinness Book of World Records. That seems odd.
Speaking of the WMAP, the Nobel Prize for Physics in 1978 was partly won by a man named Robert Wilson, whose discovery of the cosmic microwave radiation background served as a confirmation of the Big Bang Theory, and is obviously a direct link in the chain from the theory of the Big Bang to the WMAP.
My dad's name was Robert Wilson. And my brother's name is Edmund Wilson. So when it comes to namesakes in my family, we have:
Robert Wilson: Nobel Laureate in Physics, partly responsible for discovering the origins of the universe.
Edmund Wilson: the preeminent literary critic of the 20th century and F. Scott Fitzgerald's "intellectual conscience."
and then there's
Greg Wilson:
Sigh.
