I’m quite confused with regards to photon emission throughout the creation of the universe.
From what I’ve heard, there was no light (of any frequency) in the universe until 300,000 years after the Big Bang. This because then the universe cooled down enough to allow for atoms. However, it seems that electrons were created at ~3 minutes after the Big Bang. In this big electron soup, where they are constantly being thrusted around, aren’t they being accelerated and hence would release radiation? Then there should be light due to the accelerated electrons (just like how accelerated electrons produce radio waves right?)
