There is no proof Evolution has ever taken place. I asked in a previous question if anyone knew of any solid proof that Evolution had ever taken place. I was given many varied answers. Most of them basing it on adaption rather than Evolution. The evolving of one species into another, to the point both species now not being able to mate with one another. This has never happened. The fossil record does not prove this which was Darwins best evidence at the time, which later he acknowledged as an embarassment. However now with the amount of data we have there are no evidence of evolution still. Yet people still believe, almost like a religion. Even W R Thompson the director of the Commonwealth Institute of Biological Control in Canada who wrote the Intro to the centennial edition of Darwins Origin of the Species wrote that this book offers no conclusion and is mearly one mans theory, which it remains to this day. Comments welcome, other theories too.

In cloud chambers one can clearly see the beginning and direction/end of a path of an entering alpha particle. Why would this not appear simultaneous to the eye ? Is the particle being slowed by the collision with the vapor within a meter ? If the cloud chamber woud be much larger, would it come to halt ?
(Thanks, from a physics neophyte)
