I'm writing my tattoo artist and thought I'd share this progress with you all. I'm planning on a CMB tattoo eventually put on my right inner bicep.
CMB=Cosmic Microwave Background Radiation
Also known as the "afterglow" of the big bang.
In general, the radiation is everywhere and between 2 and 3 Kelvin. That's 2-3 degrees above absolute zero, in the vague range of a half meter wavelength, in the microwave region.
I realize this material might take a few minutes to grasp, but this is the BASIC image for my tattoo along with the information behind it. I'm going to have to really, really mess with the thresholds of colors and the contrast in order to dumb down the intense amount of detail in this. THIS is the universe's background radiation IF you cancel out the light coming from the milky way. It's like a world map. It's a map of the entire universe.
So yes, I'll have to photoshop the bitch for a while.
The first paragraph and multiple images in the link above explain fairly simply how we can cancel out the glow from the milky way and make a picture of JUST the universe's glow. Many WMAP images (WMAP is the probe gathering the data) have red lines along the center. THAT is the milky way.
Technically this picture is called "The Internal Linear Combination Map" which is "computed using criteria which minimize the Galactic foreground contribution to the sky signal."
