Re: Where are they moving to?
Are they on the edge of the universe? Yes there was nothing and then it exploded, but if they're the oldest galaxies are they the furthest things from us? Is the universe ball-shaped and are we on the inside or the outside of the ball? Where is the centre and where did it explode from?
It gives me such a headache to try to understand it.
Got aspirin? Here's a layman's view:
That galaxy's not at the edge, it's exactly in the center. Just the same as everything else in the Universe, including you, me, and that thing over there. Any point in space is the center of the Universe, because there's no 'outside' or 'edge' to it as far as our understanding goes. (Real brainbreaker: There is nothing outside the Universe, not even the Universe, because it only exists within itself!)
It's all center, but the center is getting bigger!
Oh, and that galaxy's not moving to anywhere.
It and everything else in the Universe is moving away from everything else. (Re: The center is getting bigger)
Space is expanding at (apparently) an ever increasing rate, but matter remains the same size it was when it was formed, so there's always more space between the big lumps (galaxies) than there was before. (stars and stuff in galaxies are close enough for gravity to hold them together despite expansion.)
