Welcome back, Spherical Cow Moonions!

This week we are continuing our discussion about the history of the universe and once again talking about 380,000 years after the Big Bang. We will be discussing the formation of sound waves in the early universe and how studying the imprint of these acoustic oscillations of the Cosmic Microwave Background map can tell us lots of fascinating information about our universe!

Please see some additions/amendments to our discussion below:

13:42 - Sorry! I meant to say that you can do some calculations and see if they agree with your observations (i.e your measurements of the size of the ‘spots’ on the cosmic microwave background map).

https://www.esa.int/ESA_Multimedia/Images/2013/03/Planck_Power_Spectrum - This is a link to the CMB Power Spectrum graph we discussed in our episode - the measurements were taken by the Planck Satellite
