Q: Are evolutionist’s theories changing?

Received this in my inbox today and thought it very interesting.
Not entirely sure who wrote it, but you can find more info on this sort of stuff here.

"A: According to the widely accepted theory of the big bang, the universe is supposed to still be expanding.
But astronomers studying supernovas have found evidence that the expansion of the universe is actually accelerating—the opposite of what was predicted! Evolutionary scientists admit that this could have enormous ramifications on theories of cosmic evolution. They were hoping they’d developed a theory of everything—but once again, they’re frustrated.
Have you ever noticed that evolutionists are so sure that they have the answers to how everything began and that the Bible has to be wrong—yet every time a new discovery is made, it’s the evolutionists who have to change their theories! The only true thing about their evolutionary theories is that whatever they believe to be truth today, seems to change tomorrow!
But God’s Word NEVER changes. It’s NOT subject to modification every couple of years when a new discovery is made about the universe. If you really want to have the absolute, unchanging account of everything, go to the book of Genesis."
