I have been modded troll. Apparently I wasn't clear enough.

Science does not claim to know the truth, because it only deals in falsifiable conclusions. Instead, science endeavours to shrink-wrap the tightest possible boundary around the truth, by following a discipline of self-examination and self-correction. For this reason, I assert that science is the best possible way to pursue the truth.

However, I admit that not all truths can be pursued with science, because not everything can be observed and analyzed by a scientific method. Love, spirituality, the arts, etc., can all claim to pursue truth in their own way.

an inaccurate scientific prediction is wrong by definition, i.e. it cannot be used to prove anything.

That depends on whether the inaccuracy matters in context.

For example, Newton's laws of motion and gravitation do an excellent job of predicting the motion of the planets. Yet, they have a very small but measureable inaccuracy in the prediction of the precession of Mercury's orbit. Einstein's theory of gravitation corrects this inaccuracy. That doesn't mean Newton's laws are "wrong" -- they just have a limitation to their applicability.

Yes. The Earth has recently been shown to not be sphere-shaped (it's more of an oblate spheroid), so if you have data that shows it's actually a sphere that would indeed need a citation.

Strictly speaking, it's not even an oblate spheroid, but very slightly pear-shaped.

For more details, read this excellent essay by Isaac Asimov.

Can we please stop tacking -gate on to the end of every scandal?

It's not clever when everyone is doing it, especially with trivial crap like this.

Believe me, I'm not keen on corruption of language (see my other posts.) But you have to admit, the "-gate" suffix is kind of useful. And it has some staying-power, as a result of the Watergate scandal.

Eventually it will become an anachronism and disappear. For now, let's not get too worked up about it.

Conservation of linear momentum is a mathematical consequence of translational symmetry - in other words, momentum is conserved if the laws of physics are invariant in space. Similarly, angular momentum is conserved if the laws of physics are invariant by rotation.

And energy is conserved if the system is invariant over a translation in time.

Hooray for Emmy Noether.

This might be another Cold Fusion moment. Or, it might be the start of something very interesting.

When an experiment contradicts a theory, there are two possibilities: (1) there's something wrong with the experiment; or (2) there's something wrong with the theory. If the correct answer is (1), then it's par for the course: mistakes happen, and the process of science corrects them eventually. But if the correct answer is (2) then it's cork-popping time, because you have discovered new science.
