You deny heliocentrism? On what basis? What is the alternative? Geocentrism has certainly been proven false.
Actually scientists DO "think stuff up". There would be no point in doing the experiments or making the observations otherwise. Those are tests.
You are agreeing with me while saying you disagree. Scientists do think up stuff but then they have to back it up. Everyone thinks up stuff. Heck if thinking up stuff was what science was about perhaps the Enquirer or the Star should be our greatest source of scientific information. I do not believe that's the case.
That is not quite the case. You can use the Earth as your frame of reference. In fact, one of my orbit classes at NASA did exactly that. We used the Earth as a frame of reference instead of the sun when we described the celestial sphere. (It described the Sun orbiting the Earth in that reference frame.)
Oh, of course not. I defined my terms very carefully. I said that it's not a "scientific fact," which I defined in turn as being a "well confirmed observation." We do not directly observe heliocentrism, we infer it from a multitude of individual facts. Or, rather, more formally, as Popper would put it, we hypothesise heliocentrism and find that it passes the test of the facts.
