So, what did the Universe look like
in its early stages, and what exactly
was the big bang?
A lot of the detail about the early
stages of the Universe is unsure.
The big bang is just a suggestion that
scientists have made for a convenient
way to start everything.
If we look far enough up into the sky
to light triggered when the universe
was very young, we can tell roughly
what was happening at the beginning.
