The motion is consistent with an expanding universe. It gets exponentially greater the further away you go, and everything is moving away from everything else - not away from some "center" position. Also, some of this movement is faster than the speed of light, and the expanding of space explanation is consistent with our understanding of physics whereas proper motion is not consistent with our understanding of physics.

This just sounds weird, like I thought that Newtonian or Einsteinian physics explained objects with velocities regardless of what those velocities are. I thought there were somehow complete, you know? I don't really understand any of it, but I read a popular account of relativity by Einstein, and you know, the examples were very 100 years ago, trains, light, geometry and stuff. No magic. Space literally expanding seems like this star trek thing jumping out of nowhere, and it's confusing to me where it comes from, even though I appreciate that it's orthodoxy nowadays. Maybe the point is the magic has something to do with general relativity?
