It's also commonly called "Microwave Background Radiation" because where the radiation peaks at 160.4 GHz is in the microwave range of the electromagnetic spectrum. --[[User:Dangerkeith3000|Dangerkeith3000]] ([[User talk:Dangerkeith3000|talk]]) 18:02, 13 March 2013 (UTC)

;Error - Inverted graph!
 
Am I the only one who came here confused because the graph is wrong? The shape of the graph is clearly that of blackbody radiation - on a wavelength axis! However Randall titles the axis GHz (pointing right) which is the inverse of wavelength (of course on a wavelength axis, the curve should not extend down to zero). But look up the graph on Wikipedia, and notice that it's on a wavelength scale and looks exactly like this - even better, google "black body radiation" images, and notice how ~95% of them show the radiation on a wavelength scale for some reason. But scroll down, and eventually you'll see one on a frequency scale. It looks quite different!
 
Also, the blackbody radiation is known for its rather sharp high frequency cutoff (or low wavelength), which Randall accidentally got inverted here, and placed at zero... It shows much more dramatically on frequency axis, which is why you can very clearly see that this graph is NOT a radiation graph on a frequency axis - it goes on to infinity.
 
Anyway, sorry for the rant - but it's Science bitches, and axis' matter! Especially if you are going to invert one of them!  - Richard [[Special:Contributions/162.158.134.16|162.158.134.16]] 22:56, 28 June 2018 (UTC)
 
 
I don't think it's inverted. We are not plotting against -wavelength but 1/wavelength, so it's plausible to have the sharp drop on the left. I haven't plotted it for myself, but see for example https://www.researchgate.net/figure/A-plot-of-the-intensity-of-the-radiation-of-a-blackbody-versus-frequency-for-temperatures_fig2_259735413.

So no one's gotten the bonus points yet?!  He was asking to identify the science in question.  When he says "It works", I'm sure he was not meaning that blackbody radiation works.  This graph was the key to one of the biggest leaps in human understanding.--[[User:ChrisfromHouston|ChrisfromHouston]] ([[User talk:ChrisfromHouston|talk]]) 06:23, 8 September 2014 (UTC)

:He meant that Science in general works. And this is just an example that proves this point. And he has explained what the graph is on his own page in the shop. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 20:16, 30 April 2015 (UTC)

Is the description supposed to say 273 Kelvin? I don't see the significance of 2.73 Kelvin.
