I recently highlighted several essays in the FARMS publication, Astronomy, Papyrus, and Covenant. I want to return, briefly, to the chapter, "'And I Saw the Stars': The Book of Abraham and Ancient Geocentric Astronomy," by John Gee, William J. Hamblin, Daniel C. Peterson.
The essay argues that the Book of Abraham is presented from a geocentric point of view. In answer to the question of why God would teach Abraham using a "false" conception, the authors suggest that (i) God teaches according to our human limits of understanding, and (ii):the geocentric view of the cosmos is not, strictly speaking, false. If modern relativistic physics has taught us anything, it is that there is no absolute space, and thus no privileged point for observation of the cosmos except as has been established by convention. The geocentric system was abandoned, in the last analysis, not because it was incorrect but because, as it had developed with its cycles and epicycles, it was too complex and cumbersome. ...it would still be possible today, in light of modern relativistic physics—and if we were willing to subject ourselves to the difficulty of doing so—to construct a description of the universe that assumes the earth to be at the center.
As currently indicated on the sidebar, I am reading Timothy Ferris's Coming of Age in the Milky Way, and he made a point that I had not thought of before, and if I understand correctly, means that the quote above is incorrect (aside from the historical reason for rejecting geocentrism).
(Note: you physicists and astronomers out there--tell me if I've got this right or not.)
From a geocentric point of view, the farther away the stars are, the faster they have to move in order to circle the earth. Astronomically speaking, you don't have to get very far (I guess a circumference of one light year) before the velocity of the stars would have to exceed the speed of light in order to circle the earth every year. This would violate a fundamental principle of relativity. So the irony here is that the authors invoke relativity to support a notion that actually contradicts relativity. Sure, we could generate such a description, but it would remain "false."
Is this right or am I missing something?
Update: Whether the issue I raise has merit or not may depend on the assumptions of the model. But I'm encouraged that at least one person has noticed the problem before. See A Critique of Geocentricity.
