scientific theories, once held as fact, that have been dis-proven

You cannot put a saddle on an Elk. Mule Deer , yes.. but not and Elk.

The atom is the smallest particle in the universe.

Heavy things fall faster than light things

Newtonian physics, Newtonian gravitaion. Technically incorrect, factually speaking. Failing point: speeds approaching c, velocity of gravity. Both still incredibly useful, of course.

The Greeks once, not only thought, were able to "prove" that the Earth was the center of the universe and everything in the sky revolved around It. It was not until we realized that the Earth was rotating and revolving around the sun that it was proven to not be true.

That X_fit_the_real_one dude destroys scientific theories on a daily basis here in letsrun.

This is great.

Organisms were created as they now are and don't evolve. Atoms are the fundamental unit of matter. CO2 does not affect the energy budget of the earth.

That Lance Armstrong's superior lung capacity, not performance enhancing drugs were responsible for his "success".

Thanks for asking this enjoyable question. Some fun ones here:

"Science" has been wrong before, therefore, we can never believe anything "science" concludes from now on no matter how concrete the data seems.

Technically he did have superior lung capacity

That footballs aired up in a warm room loose PSI when taken outside to colder conditions.

Really? You want to rail against trivial BS that people focus on and then waste your time on posts like this.

Actually in the 3rd century BC Aristarchus believe the Earth rotated on its axis and revolved around the Sun.

You can arbitrarily put the "center" of an unbounded coordinate system anywhere you want to. There's a lot of convenient reasons to put the origin where you're standing.

White superiority, unwittingly disproved by George W. Bush.

the 'center' is pretty arbitrary

who is revolving around whom is not so much.

People really used to think that plants eat dirt.

And some people still think plants 'eat'!

Scientific theories are never facts. They are models. Scientists work constantly to disprove the current model and replace it with a better one. Failure of a theory equals success of science and reiterates the power of requiring evidence for one's views about whatever is being studied. If a theory can't generate any testable hypotheses it's not science.

Bloody well said. I would disagree with your statement "Scientists work constantly" though. Personally I can often be found slacking off and posting on Letsrun.
