Reply to comment by Wyvernrider in 87 newly-discovered galaxies, found using Webb space telescope, could be earliest known galaxies in the universe — the first indication that a lot of galaxies could have formed much earlier than previously thought by marketrent

Thats what redshift is, and they're using that "distortion" to measure the age of the galaxies.

I'm not talking about simply the speed at which objects are moving away from each other's effect. I'm talking about the effects of all the objects in-between such as other galaxies.

Yes and the matter that is in it is not evenly distributed - it tends to bunch together, and at the largest scales, it looks like a foam, with all the matter distributed along the edges of the bubbles, and really big empty spaces in between. I mean, there's an area of space that's a billion light years across, and there's nothing in it, as far as we can tell.
