"Right now, everything is moving away from us in proportion to its distance from us." From us? So does that mean that we are at the center of this expansion?

- goodside 17y agoIf it were inertial expansion, in the sense of movement in the usual sense through space, yes it would. That's obviously a big problem, and confused a lot of people in the early parts of the 20th century. Metric expansion fixes this absurdity, since when spacetime itself is expanding it is everything that moves away from everything else. No matter where you stand, you appear to be the center that everything is running away from.
