Extraneous information[edit]

The following should be removed as it is not about Vesto Slipher. I understand it is a reference to the impact of his work but that is made implicit by the linking in the previous paragraph.

"Earlier, in 1917, Albert Einstein had found that his newly developed General Theory of Relativity indicated that the universe must be either expanding or contracting. Unable to believe what his own equations were telling him, Einstein introduced a cosmological constant (a "fudge factor") to the equations to avoid this "problem". When Einstein heard of Hubble's discovery, he said that changing his equations was "the biggest blunder of my life".[4]" Miglewis (talk) 13:05, 8 September 2008 (UTC)

Name[edit]

It is not clear to me which language the name "Slipher" is in and how he pronounced it. —Preceding unsigned comment added by 86.160.202.155 (talk) 09:01, 24 September 2008 (UTC)

It might be Skandanavian. —Preceding unsigned comment added by 86.160.202.155 (talk) 09:57, 24 September 2008 (UTC)


As a Indiana University graduate, the name is pronounced Sly-fur among those I've spoken to in the Astronomy department.Miglewis (talk) 17:21, 10 October 2008 (UTC)

Cosmological redshift - question[edit]

Are the redshifts discovered by Slipher of cosmological significiance? The galaxies close from the Milky Way are not receeding. Even velocities of close receeding galaxies are still out of the distance-redshift relation. Does Slipher mesured the redshifts of galaxies at more than a few Mpc?
