And so that's why now
when we look at the sky and we see that two different parts
of the universe that should never have been
in contact with each other are the same temperature, it's because you can dial back

never in contact, but then there's this extra
secret time at the beginning where they did communicate, and then they just were, sort of,
pulled apart so quickly that, you know,
we can only infer that that happened by the fact that they must have been
in contact at some point
