What do you think produced the cosmic microwave background?

Remember the words of Douglas Adams:  "Space is big.  Really big.  You
may think it's a long way to the corner chemist's, but that's nothing
compared to space."

And there isn't that much mass in the universe, compared to the amount
of space.
