Tribute Games' take on Marvel comics focuses on the universe's more overlooked cosmic elements and packs a delightfully off-beat roster of heroes.
So first the Big Bang happens. Everything is incredibly hot and dense; there are photons flying everywhere, but they keep colliding with electrons and ionized nuclei. Then, finally after about 380,000 years the cosmos is becomes cool enough for atoms to stabilize. The Universe becomes optically transparent, and all those photons are able to roam free for billions of years, allowing us to see them as the cosmic microwave background.
