Dear Students,

The following things are not evidence for the expansion of the universe:

1) Extrasolar planets (huh?)
2) Dark matter haloes
3) Discovery of new distant galaxies
4) Formation of stars and galaxies
5) Watching things move/get fainter (Which we can't see, except indirectly measuing velocity by Doppler shift)

I expect to add to this list.
