Describe what the universe was like before recombination and how photons were influenced.

Before this time, the Universe was opaque. Immediately after the Big Bang, the Universe was extremely hot and dense. Under these conditions, atoms could not exist, and the matter was distributed as a highly ionized plasma.

Prior to recombination, photons were not able to freely travel through the universe, as they constantly scattered off the free electrons and protons.
