Gosh, if that really was your grand exit I shall rejoice at the thought that the world's balance has tipped just a fraction more towards rationality. As for the speed of light in a vacuum, well there is truth there somewhere, but let's remember that seconds and metres are our own constructs and that the obstinate fact remains that the speed of light in a pure vacuum has never been observed and can be assumed by extrapolation only. Perfectly reasonably in my view, so much so that I'm prepared to accept the arrived-at value as truth. I like truth. Truth is there for us to find, but only via science, never by religion.
