"Common sense" is geocentric. Go into outer space and your common sense is not going to work for you. Jumping in the air will fling you on a path; you will not drop back down.
Common sense is what leads to the argument for the earth spinning and moving around the sun. How is the following not plain common sense (which I suppose is induction of a sort) applied to the phenomena?
1) Spinning objects on the earth exhibit certain unique phenomena.
2) Observed spinning objects in the heavens exhibit the same unique phenomena as spinning objects on earth.
3) The earth exhibits this same set of unique phenomena.
4) Therefore, the earth is probably spinning.
Or how about (although it involves more abstract entities, the reasoning is still genuinely inductive)?
1) Objects that move around each other on earth orbit a special mathematical point that we can calculate. This mathematical point tells us which objects appear to move around which objects when we look at them with our own eyes.
2) Objects in the heavens that move around each orbit the mathematical point that is calculated in the same way as on earth.
3) Calculating this mathematical point for the earth and sun, we find that the mathematical point is inside the sun.
4) So the earth probably moves around the sun and not the other way (in the sense that this is what we would see with our eyes).
It is certainly true that things are not always what we see ("bent" stick in water example); neither are things always in accord with common sense (your example of jumping in space); but these are phenomena that do not go away by a change of dynamical model (indeed, I think these observations are granted by geocentrists): they are observed, and there are ways to tell whether what we see is an illusion or not ("bent" stick in water example) and some ways to detect illusion exist in the case of geocentrism vs acentrism. I don't see how these observed phenomena could be explained in a geocentric dynamics without making the physics of the earth--as a body--behave completely differently from every heavenly and earthly body. I'm not saying it is absolutely impossible: that is too dogmatic from a scientific perspective. But from the perspective of common sense induction: if it behaves like it is rotating, it is probably rotating, unless someone can prove otherwise.
That is what I was talking about with the metaphysics of geocentrism seeming to destroy common sense: we have to deny that we can determine that something is rotating if it exhibits unique phenomena associated with rotation. If one was on another planet and saw this same phenomena, none would hesitate to conclude that the planet was rotating; likewise, if one was on a merry-go-round, one would observe the same phenomena and not hesitate to conclude that one was rotating, rather than the earth spinning around the person on the merry-go-round.

What distance? According to physics the universe is expanding and time is in flux. How long is a piece of string? Any finding could only be relative.
The piece of string does have an invariant length according to modern physics. While that length could be measured in different units, the length remains the same. By "distance," I mean far enough away to get a good perspective on the matter. But I think that all that is really required is to be in a position of space that does not share the motion of the sun and the earth and does not block the view of the earth-sun system.

According to modern relativist physics matter is eternal and infinite. According to the Bible there is a beginning of things and these are quantifiable. According to the relativist theory there might be multiple realities. According to the Bible there can only be one, of which there can only be one God. Although on this last point there are those who point to the improbability of multiple realities it is still regarded as a theoretical possibility.
Ah, good point. When I was speaking of the metaphysics of relativist physics, I was not intending to refer to all the extra metaphysical baggage that people add to the physics in an attempt to find an ultimate explanation of life. I was merely referring to the metaphysics of motion in the relativist physics. Since no objection was raised to the relativist physics on this ground (since it acknowledges that the sun moves when one is on earth), it would seem there is no conflict between this metaphysics and the truth of Scripture concerning the sun's motion?
(For those interested, an interesting comment by an
expert in general relativity. However, it seems to me that the way "experts" interpret general relativity depend on prior metaphysical assumptions and assumptions about the philosophy of science; those with a less "realist" view of science tend to hold to a more "relative" view of general relativity. I have still not been able to get to the bottom of this difficulty yet.)

Here is Neil deGrasse Tyson's rule number one:
(1) Question authority. No idea is true just because someone says so, including me.
I don't see how this is a precarious view of matter and time. I may be missing the point.
