I’ve been reading. Normally, that isn't too big a problem.
I've learned the universe is most commonly defined as the totality of all existence, to include the planets, stars, and galaxies, and the contents of intergalactic space, as well as all matter and energy. Further, it is believed the universe is at least 10 billion light years in diameter.
You gotta admit…that’s pretty honkin’ big.
Here’s the part that bothers me. Most scientists believe the universe continues to expand. Not unlike the ever growing circle of ripples in a pond of water, the universe continues to grow.
If the universe consists of, and contains everything, into precisely what is it expanding?
