All of the talk about finding a new distance record for farthest galaxy from us has fed my interest in the concept of universe expansion. I had three questions that hopefully someone here can help me understand.
First, because of the fact that all galaxies are moving away from each other, does that mean that some (those on the leading edge) galaxies are travelling faster than other galaxies?
Two, regarding the new farthest galaxy, is it further out than the center (at least the percieved center, but I'll get to that in my next question) from us or are astronomers looking back to the farther edge?
Finally, addressing the center of the universe - looking for information on this subject, I found this on the Bad Astronomy website

It looks as if we are at the center of a gigantic explosion that made all the galaxies blow outward from us. This is an illusion; any galaxy would see the same thing. They aren't really moving away from us; we are all moving away from each other. We're not really at the center (as a matter of fact, there wasn't any center, but this is complicated enough!).

can someone help me understand how there is no center?
Sorry, if my questions seem silly, sometimes I have a hard time conceptualizing that which I cannot see.
