The Hubble Constant's current estimated value... (choose best answer)
1) tells us that every galaxy is moving away from us at 68 km/s/Mpc.
2) describes recessional velocity that depends solely on the distance from the Big Bang.
3) tells us that non-local galaxies and galaxy clusters are moving away from one another at a relatively constant 68 km/s/Mpc.
4) describes recessional velocity that depends solely on the time from the Big Bang.
