Not quite sure what you're saying, but no, everything isn't traveling from Earth at the same speed. But I'm saying wherever you are in space, you'd see the same frequency if you look far enough as you see on Earth? So, our observable universe is about 46b lightyears in radius. To us, we're at the center right? We see a redshift of x when looking straight "up" to the very edge of our universe. If we can teleport to this this spot instantly and look around us, we'd still see a universe of about 46b lightyears in radius (just would be mostly different things as you could see from Earth. If you then looked straight "up" from this spot, you'd still see the same redshift of x as you saw when you looked at your current spot from Earth. So, how could you ever tell what the central point is if everywhere you go, you'd have the same size observable universe and same shifts?
