Yes, there's always a footnote in science that new evidence could conceivably come up that would challenge the theory. But a new hypothesis would have to be worked out to explain both the old and the new evidence, then be thoroughly tested before it could graduate to the level of a revised theory. Some old book will hold zero weight in the discussion regardless.

I'm not disagreeing with you - I'm just pointing out that a majority of people are fairly ignorant when it comes to science and they take everything that a scientist says at face value, no different than how most people are fairly ignorant about spirituality (place/significance in the universe) and take everything that a cleric says at face value... A theory is not a hypothesis, but its not a law either - most people don't (can't?) make the distinction... They tend to fall back on belief instead of trusting in scientific rigor, but I guess even scientists can get sick of answering the question "why?" over and over - especially since there's more grant money in answers than questions (hello, peak oil and global warming debates?)
A potent mixture of greed and ignorance is turning science into another religion, which is diluting its ultimate purpose: the search for truth (which happens to be the same place where religion started...)
Maybe our current theories about our origins are correct, but there's a pretty decent chance that whatever the actual truth is will make those theories look as ridiculous as anything you can find in a religious text... Claiming that we KNOW anything at this point is a belief, and any responsible scientist can admit that... Hell, we don't even know how consciousness works - how can we pretend to know how the universe works??

Wow...that is a wild, wild claim. And it certainly does not mesh at all with my experience. What are you working off here?

Maybe you are referring to a hypothesis.

Newton's LAW of Universal Gravitation is not a theory, it's a fact... Do you know what a theory is?

While the law lets us calculate quite a bit about what happens, notice that it does not tell us anything about why it happens. That is what theories are for. In the language of science, the word "theory" is used to describe an explanation of why and how things happen. For gravity, we use Einstein's Theory of General Relativity to explain why things fall.

And as your article states, "Newton's law has since been superseded by Einstein's theory of general relativity."

The theory of relativity, on the other hand, is not so measurable - you'll just have to rely on faith unless you have a Millennium Falcon, since the stepping stone between theories and laws is tangibility... Which is why most science (especially theoretical science) is dependent on consensus - no different than religion (take a look at how the Talmud was assembled for reference.)

Actually the theory of relativity is very measurable. Your iPhone would not work without time dilation.
Here is a list of various tests for the theory of relativity:
http://en.wikipedia.org/wiki/Tests_o...ral_relativity
And back to the topic of the discussion, the age of the earth is very measurable. Saying it is any younger than a couple of billion of years makes you look like an anti-science loon.

Good thing I never said that...

I'll have to go through the rest of this thread sober. For now, Krugman is a fanatic rockstar of the left and used plenty of fanatical fear mongering in that article. Wish he'd stick to econ from a puristic view.
