Speed of light not constant = young universe

[Jenny A]

Reminds me of a discussion in metaphysics class beginning with the premise that space was stretched out in one direction causing objects and space the lengthen as you turned into the stretched direction. Once someone proposed light and sound and other things would travel proportionally faster in the elongated direction we gave it up as an untestable, and ultimately unimportant idea. No difference could be demonstrated even it it were true.
