Talk:Superluminal motion

From Wikipedia, the free encyclopedia

Can someone post a diagram. This is one of those things that is very easily explained on a blackboard, but hard to explain with words. Roadrunner 20:24, 25 Feb 2004 (UTC)

First the blob is moviong towards me and then the blob in on a path perpendicular to me. This doesn't seem to match another explanation I found but I don't fee comfortable changing it.

[edit] More explanation needed

This result is not that intuitive (if the object is moving mostly towards you, the tangential velocity cannot be very high, and it is not obvious that the time interval decreases faster), so I think a quantitive treatment is necessary, something like the explanation here. I'll add that as a "See also" link before someone gets around to do a good explanation here. R6144 09:54, 23 August 2005 (UTC)
