What exactly is this a map of? Why is it an oval?

>>8140955
It's an all sky map of the CMB. Use google.

>>8140955
Its what the universe looks like from earth

>>8140964
No it's not, unless you "look" with an extremely advanced and specialized microwave detector.

>>8140969
Correct

>>8140969
Which naturally is radically different from our extremely advanced and specialized visible light detectors in our heads.

This map isn't even that informative. The main thing you care about is that the dark blue areas and the red areas actually represent very very minute variations in temperature.

It's supposed to be a sphere that you're sitting inside of, it's stretched into an oval so you can see the whole thing at once. Since heat is the result of friction during motion, the greener parts are the parts of the universe that were moving more actively

like 60 seconds

Google is your friend btw... but in the interest of spreading some knowledge, its an oval shape because that projection preserves area, which is important in this case when one wants to know the average temperature (per unit area).

>I have no idea myself, but any question in /sci/ gives me the opportunity to feel good about myself by smugly pointing out that the answer can be found via a popular search engine.

It’s 0.0002 degrees
