I did not ignore all of the other evidence presented, the arguements in the article had little to do with my original point. I felt my point was neatly summed up in the one simple sentence so I quoted it. In fairness, the only unarguable evidence offered in the article (aside from extraterrestrial observations, mentioned in the first sentance) is traveling around the globe documenting shifts in the positions of constellations relative to the horizon. Not being Captain Cook, I doubt that I will have the oppertunity to do this any time soon. Also not being Alan Shepard, I don’t think I will have the unique experiance of viewing the earth from an astronomical perspective. But, in the interest of not dodging the question:
http://en.wikipedia.org/wiki/Flat_Earth
So, yeah, the concept of a flat earth predates the concept of scientific theory and about the time scientific methods came on the scene, the whole flat earth thing was the first to go. Although a bad example on my part, it is still incorrect to say that no one believed the earth was flat, ever.
And it is my reading comprehension that is in question here? Before I ran all the definitions together, I offered them seperatly, although without numbers. A bit of lazyness on my part there, but still they were intact with, what I was trying to point out as the key words highlighted. After the initial listing, I did group all of these key words together to emphasize their consistancy within the broader definition.
A theory is just a theory. The attitude you describe above reflects that, and also reflects my point. An attitude of “This is the best explanation we have so far…” is a lot more productive than “Evolution by natural selection that was started by a chance chemical reaction is the only possible answer, deal with it” or the ever popular “Things are the way they are because God made them that way, and that is that”. Neither of these are good arguements.
I’m not saying that theory is “wild speculation”, just that holding true to a theory is limiting because a theory is not a fact. Even in your definition you state that a theory is a set of explainations, not a set of truths or a set of facts. Gravity is a great example, as you mentioned. I drop an egg, gravity works. I see the moon not falling on me, gravity works. That gravity works is a fact, that gravity exists is a theory. It would be a fact to say that “something” exists to which we assign the propertys of gravity, but what is it? Does it push or pull? Is it a particle or a waveform? Can it, or it’s effects be accurately replicated completely independant of the original phenomena (good luck with this one)? These are the holes that make the theory of gravity a theory instead of a proven fact. Different observers might come up with equally plausable, and equally unprovable explainations for gravity. These are theorys. The earth is round is a proven fact. Surface observations combined with external observations have dealt with this. Black Holes are a theory, something is out there doing things with light, we can observe and measure the effects, and theorize what that something might be, but not see it directly, we cannot interact with it, experiment on it. Someday we might be able to, but not today. Until then they are a theory, an explaination of observable, testable and repeatable facts. But not facts themselves…yet.
