Central Alberta | In simple terms, the earth rotates around the sun once a year, and the sun rotates around the galaxy about every 230 million years.
In less simple terms, everything in space is relative, so there's no way to be sure how fast anything is moving, except in relation to something else. To complicate things further, the universe is expanding at a n accelerating rate, but it's not actually moving apart; it's just that space itself is expanding.
If that makes any sense. | |
