The Geocentric and Heliocentric model

How do we reconcile the Vedic idea that the sun moves around the earth with the scientific idea that the earth moves around the sun?

How geocentric and helio-centric models are equivalent due to the concept of relativity:

-          From Vedic Cosmography from Richard L Thompson (Sadaputa Das)

The watershed in the development of modern astronomy was crossed when Copernicus replaced the ancient geocentric model of the universe with a heliocentric model. Although the relative merit of the two models was initially debatable, the development of Newton's laws of motion seemed to give overwhelming support for the heliocentric model. This can be argued as follows: If the stars and planets are rotating around the earth once per day, then they should be subjected to tremendous centrifugal forces that will have to be counterbalanced in some way. Isn't it more reasonable to suppose that the earth, which is much smaller and more compact than the universe as a whole, is rotating on its axis? Likewise, isn't it more reasonable to suppose that the small earth is orbiting around the massive sun than to suppose that the sun is orbiting around the earth?

This objection can be partially answered by invoking the idea of relativity of motion. Consider two objects, A and B, that are approaching one another at a constant velocity. According to classical physics, there is no physical difference between saying that A is standing still and being approached by B and saying that B is standing still and being approached by A. Thus, as far as physics is concerned, no objection could be raised to either statement.

In classical physics this relativity of motion is not thought to apply to rotation. Imagine an axis running from the center of A through the center of B. Suppose that A is rotating with respect to B on this axis. According to classical physics, rotary motion generates centrifugal force, and thus the actual rate of rotation of A and B can be determined by measuring this force. Thus if A exhibits a certain amount of centrifugal force and B does not, the conclusion of classical physics must be that A is rotating and B is not.

However, the physicist Ernst Mach once made the following argument: Suppose that A and B are the only objects in the universe, and suppose that they are of equal mass. Then why should it be that A shows measurable evidence of rotation and not B? After all, if we say that A is rotating, then what is it rotating with respect to? If B is the only other object in the universe, then A could only be rotating with respect to B. But it could equally well be said that B is rotating with respect to A. Thus Mach concluded that neither A nor B would exhibit centrifugal force if they were the only objects in the universe. He proposed that centrifugal force is generated in one object due to the rotation relative to it of another, much larger object. Thus, Mach maintained that if A is rotating with respect to the rest of the universe, then one could equally well say that the universe was rotating with respect to A and thereby generating centrifugal forces in A. Mach's argument implies that there are no physical grounds for rejecting the statement that "A is standing still and the universe is rotating around it."

Here one might object that the rotation of the earth is directly indicated by the Foucault pendulum experiment and the evidence that the prevailing winds are affected by Coriolis forces. Also, the rotation of the earth around the sun is indicated by a number of minute but measurable effects, such as aberration of starlight and the parallax of some stars.

It turns out, however, that Mach's argument also disposes of these objections. For example, Mach would say that the rotation of the Foucault pendulum can be attributed to the rotation of the massive universe around the earth, just as well as to the rotation of the earth under the pendulum.

If this idea of relativity of motion is granted, one can then argue that the geocentric or heliocentric viewpoints stand on the same footing physically, and we can choose one or the other, depending on what is convenient. In the case of the astronomical siddhantas, we could argue that the geocentric viewpoint is simply the more practical of the two, since all computations must ultimately be expressed in geocentric terms.
