Redshift Space Distortion[edit]

Since this article talks about both types of redshift space distortion should this page be renamed 'redshift space distortion'? Korandder (talk) 08:10, 20 January 2012 (UTC)

Solar rays[edit]

Isn't the phenonemon where you can see the sun shining through the trees also called "fingers of god"?

Perhaps colloquially, but those are official referred to as Crepuscular rays. --Bossi (talkgallerycontrib) 00:33, 15 May 2008 (UTC)

Parallax[edit]

I'm a bit confused... it sounds like this phenomena is similar to the effects of Parallax, such as how meteors always seem to fall in the same direction? Er, assuming I'm right in calling that "parallax". --Bossi (talkgallerycontrib) 00:33, 15 May 2008 (UTC)

To my knowledge there are no similarities between the fingers of God, parallax and meteors. Parallax is the effect of an object appearing to change position (relative to the background) depending on the position of the observer. In astronomy, this effect manifests itself when viewing nearby stars. They move relative to background stars depending on where Earth is in it's orbit when the observations are made. I'm not sure exactly what you refer to when you're talking about meteors falling in the same direction. If you're talking about a meteor shower then all the meteors fall in the same direction because they are all debris from the same object and so are all travelling in the same direction.

Images?[edit]

My only concern when this started - there is no damn image! The image was removed! I changed the paragraph to reflect as much, however creatively. The responsibility probably doesn't rest with the person that deleted the image, since there were other issues involved with that. The guy that reverted my changes, however, is plain wrong. If he cared enough to do anything, the least he could have done is give the article MORE sense than my meager attempt, not less. Good luck. —Preceding unsigned comment added by 98.246.32.140 (talk) 06:11, 1 May 2009 (UTC)

I agree with you. The paragraph is clearly describing an image which is no longer there and therefore the paragraph is useless. AstroMark (talk) 12:49, 1 May 2009 (UTC)
