The idea is that a theory should be consistent with everything that has been observed so far, and make predictions for stuff that hasn't been observed ... so general relativity explained some stuff that wasn't accounted for by classical physics (like some quirks in the orbit of Mercury, if my increasingly faint memory of college is correct) and also made predictions about other stuff, like light travelling from the sun to earth being affected by the curvature of space ... they had to wait for a solar eclipse to measure that one, then they measured it and it was consistent with the theory - if it hadn't been relativity would have been sunk (or would have needed to be drastically modified)Haven't read this whole thread so this might have come up, but probably not. As a borderline clueless person wrt the area of astrophysics, how does the principle of falsifiability apply? That is to say, whil I can grasp the concepts involved in the thought of Einstein or Hawking in relation to black holes or whatever, how are these theories to be tested?

Likewise for the big bang, the idea came about when people were trying to explain why all galaxies in the universe appeared to be moving away from us, and then they worked out some stuff, came up with the big bang and realised if the big bang happened then there would have to be a certain level of background radiation observable from the big bang itself ... so they had a look and lo and behold there was
Leaves a lot of scope for a Kuhnian type gestalt shift.
"Keep an open mind, but not so open that your brain falls out." (Richard Feynman)A closed mind is a terrible thing people. Accusing other people of prejudices when you clearly have some of your own is such a cliche.
this has to be the understatement of the century. I'm sure science appreciates your endorsement.I'm all in favour of science. I think science has produced some excellent ideas.
THIS IS WHAT SCIENCE DOES........ and ID consistently fails.But we should never take these ideas as truth. We need to constantly re-evaluate them based on the evidence.
If intelligent design is absolute rubbish then discussing it in science class should expose it as absolute rubbish pretty quickly no? Instead of censoring it you allow its weak arguments to be shown to have no foundation?

I dunno what wonderfully expressive and debate-filled educational facilites you attended, but in my school if the science teacher said grass was blue and writing that down in a test would get me more points, I would have done it.
the creationists world is certainly cooler than the scientific one
