Einstein did not redefine the nature of gravity (relative to that described by Newton)? I think he did. I think he described the force behind gravity quite differently. But then, I'm a potter. What do I know?

I don't think there's much difference between what you are saying and what I'm saying about science always open to new data. Well, except that I didn't do that cool underline thingy. I have corrected that with this post.

And it doesn't change what I was saying relative to the no-win situation that the original "goal posts" comment implied. Again -- when Christians ignore new data in favor of old myth, superstition, whatever, they are "lost in the dark ages". But if they choose to alter their beliefs to reflect the reality of the new data, the poster who made the original "goal posts" comment claims that these Christians are "moving the goal posts".

I'm pretty much in the "moving the goal posts" camp. I find the darn things never stay put! (once you start using that cool underline thing it's hard to stop -- it's just so.....you know....EMPHATIC!!). And I fully expect to find the goal posts in a different place then I left them most of the time. It's amazing how far away they actually are. Data just never stops.
