From Slashdot.org, I learned of a posting on a University of Washington webpage that included the above-embedded simulation of the sound of the Big Bang, and the following text.
News and Information
A decade ago, spurred by a question for a fifth-grade science project, University of Washington physicist John Cramer devised an audio recreation of the Big Bang that started our universe nearly 14 billion years ago.
As the universe cooled and expanded, it stretched the wavelengths to create “more of a bass instrument,” Cramer said. The sound gets lower as the wavelengths are stretched farther, and at first it gets louder but then gradually fades. The sound was, in fact, so “bass” that he had to boost the frequency 100 septillion times (that’s a 100 followed by 24 more zeroes) just to get the recordings into a range where they can be heard by humans.
For those who read the comments along the way:

Below are three items posted by Slashdot.net that caught my attention this morning. The first is technology/medical, the second and third have to do with US Constitutionally guaranteed rights.
It's about time some of the folks who have the big bucks recognize the worth of scientific research and development. Yay for Zuckerberg, Brin, and Milner!
(Sorry for the title that harkens back to the 1950s. Well, almost sorry.)
The following are excerpts from an Associated Press news article (linked by the title).

While major airlines offer in-flight Wi-Fi on many flights, the signal strength can be spotty. Airlines and aircraft makers have been striving to improve this with the growing use of wireless devices and the number of people who don't want to be disconnected, even 35,000 feet up.
Engineers at Chicago-based Boeing Co. used sacks of potatoes as stand-ins for passengers as they worked to eliminate weak spots in in-flight wireless signals. They needed full planes to get accurate results during signal testing, but they couldn't ask people to sit motionless for days while data was [sic] gathered.
It turns out that potatoes — because of their water content and chemistry — absorb and reflect radio wave signals much the same way as the human body does, making them suitable substitutes for airline passengers.
In a nod to the humor in using a tuber to solve a high-tech problem, researchers dubbed the project Synthetic Personnel Using Dialectic Substitution, or SPUDS.
A hat tip to Hunky Husband for emailing me a link to the article. In the interest of full disclosure, HH spent just shy of 35 years (Feb 1959 - Sep 1993) with Boeing. HH, being a pharmacist student gone bad, did most of his university work in electronics engineering and worked in avionics* engineering (1959 - 1974) and program management (1975 - 1993).
* Avionics = code for electronics used on aeronautical platforms
Addition of December 16, 2012 - just for Joared - from Slashdot.org:
Original posting - November 14, 2012
High-resolution global atmospheric modeling provides a unique tool to study the role of weather within Earth's climate system. The Goddard Earth Observing System Model, Version 5 (GEOS-5) is capable of simulating worldwide weather at resolutions of 10 to 3.5 kilometers (km).
This portrait of global aerosols [Note: not used, in this instance, to denote hydrofluorocarbons and other man-made aerosols - CC] was produced by a GEOS-5 simulation at a 10-kilometer resolution. Dust (red) is lifted from the surface, sea salt (blue) swirls inside cyclones, smoke (green) rises from fires, and sulfate particles (white) stream from volcanoes and fossil fuel emissions.

As my blog friends have proven to be a savvy bunch (witness comments to previous postings concerning particle physics), I'm sure that you are all well ahead of me in reading about and interpreting reports from CERN's LHC exerimental teams. None-the-less, I pass along the latest posting from Slashdot.org.
While I'm posting, I pass along this thought-provoking article from the same source.
Further, from the same source, comes a hopeful development that reminds me of beating swords into plowshares.
And, finally, an item from the same source - concerning an "Aha!" moment brought on by our own global pollution considerations.
