The scientists know quite well that given a frame of reference, the earth can go around the sun and the sun can go around the earth. They even know that from our reference frame…it is the sun moving, not us, so OF COURSE that’s what the ancients saw…and it’s valid.
Of course geocentrism claims that the earth is the only absolute rference frame.
They also know that there is probably no “center” of the universe (just as there is no center to the surface of a sphere) but that from our perspective…earth seems to be.
Geocentrism claims that earth is the true center, not just the center from our perspective. We do not know that the universe is like a surface of a sphere. This is what science posits to get around the observations indicating that we are in the center. This is the isotropic principle. It is also Friedman’s second assumption. Here is what Stephen Hawking said in
A Brief History of Time (as quoted in
Galileo Was Wrong):
*…all this evidence that the universe looks the same whichever *
*direction we look in might **seem to suggest there is something ***
*
special about our place in the universe. In particular, it might *
*seem that if we observe all other galaxies to be moving away *
from us, then we must be at the center of the universe.
…
*There is, however, an alternate explanation: the universe
might *
*look the same in every direction as seen from any other galaxy, *
*too. This, as we have seen, was Friedmann’s second *
*assumption. **We have no scientific evidence for, or against, this ***
*
assumption. We believe it only on grounds of
modesty: *
*it would be most remarkable if the universe looked the same in *
*every direction around us, but not around other points in the *
universe.
And yet…they always tell the Galileo story as the great folly of religion. Any little kid will tell you what science has told them: you’re dumb and foolish and old fashioned if you think the sun revolves around the earth.
When people grow up…they can start to explore the whole relativity of motion thing…but the desired gut reaction sticks: the earth is not the center of the universe. And many teenagers and adults still don’t understand and would insist that the earth revolves around the sun, and that you’re stupid for saying otherwise.
Even though the scientists know that the sun revolves around the earth as much as the earth revolves around the sun…they for some reason believe the heliocentric model being held by the lay public (against visual evidence) is best for their POLITICAL agenda.
Based on the results of the various assumptions used by science (isotropic principle, unobservibility of our motion due to special relativity, etc.) plus the idea of a barycenter, and the assumption that the universe is not rotating, science posits that the solar system is approximately heliocentric, but actually barycentric. This makes sense if the assumptions were correct. But since they are only assumptions, it is necassary to ask ‘what if the assumptions are not correct?’. What if the 1st choice given to Stephen Hawking was chosen (i.e., we are at center).
Finally, the
sun is the center of the solar system. It is a matter of what is defined as the solar system. Since the universe is rotating, and the earth is locked into place by the forces of this rotation, then the earth plays a diferent role in the operation of the solar system than the planets do. I.e., there is more going on than in the Newtonian type solar system, at least locally.
Oh, they’ll tell you it’s just because the equations are easier (not necessarily true if we’re talking about the earth/sun relationship and not other planets) but really…they for some reason want people to choose the sun as the reference point and center…and not the earth…even though either choice is valid, and frankly…using earth makes initial sense and jives better with true faith.
From an engineering perspective, you want to choose the simplest reference frame. If you are launching from earth, then earth is the easiest. If you are launching to the sun (from the earth) than start with an earth reference frame, than transform to the sun, etc. From this perspective, what Bro. Consolmagno said is perfectly reasonable. Note that he did not say that the underlying reality of the universe is non-geocentric.
And you are right, the earth does make the most sense since most of our observations are from the earth.
What is best for an engineer is not necassarily absolute truth.
