Re: Something's not right here.
"How can it be accelerating? That implies a force pushing on it. "
1. Stuff is accelerating.
2. That means something is pushing it.
3. We have no clue what it is.
4. Let's call it "dark energy", because that sounds more sciency than "Fluffy the Terrible".
What "dark energy" actually is is unknown, except that it is by definition the stuff which is pushing away the galaxies from us.
