Reply to comment by TheLostHippos in in the FAQ it is stated that one proof of the universe's expansion is that "more distant galaxies are packed closer together". What sort of measurements have been made to show this? by DanTheTerrible

That is correct.

Distance = time due to the finite speed of light.

So the detail that galaxies far away, and thus in the past, are closer supports the model of an expanding universe.

Especially as this detail is seen in all directions with no variation further supports the expansion model.
