Geocentrism

While little known to most Jewish people today, many classical texts of rabbinic Judaism taught the ancient view that the Earth is the center of the universe, and that the Sun, other planets, and stars all revolve around the Earth. This idea is called geocentrism.  Ever since Copernicus in the 1400s, and especially since galileo in the 1500s, we have known that this idea is false.

Geocentrism today is rejected by all non-Orthodox Jewish groups, and one would imagine most if not all of Modern Orthodoxy. However, some Haredi (ultra-Orthodox) groups still teach geocentrism. Here are Chabad Lubavitch essays teaching that the earth is the center of the universe:

This belief can be found in other Hasidic and non-Hasidic Orthodox groups. According to the survey a large percent of college-attending Orthodox Jews believe that the earth is the center of the universe, and that the Sun and other planets revolve around us.

“Of particular interest was the item “Which is true? The Sun revolves around the Earth [or] the Earth revolves around the Sun (Figure 8). Only 22 of 173 answered that the Sun revolves around the Earth. Geocentrism is fast returning as a centrist Orthodox belief, so the paucity of geocentrists among these college students is a strong indication of their (relatively) modern Orthodox status”

“…The Association of Orthodox Jewish Scientists is largest organization of its type with over 1500 members. Its website is http://www.aojs.org. Dr. Avi Rabinowitz, a Ph.D. in theoretical physics from New York University, who defended geocentrism in “Geocentrism” in B’Or‑Ha’Torah Volume 5E 1986 spoke at its convention in August 19–21, 2005. See Rabinowitz’s article, Egocentrism & Geocentrism; Human Significance & Existential Despair; Fundamentalism and Skepticalism.”

It has been scientifically proven that geocentrism is wrong in many ways. First, within our own solar system, it is our Sun which is the center: planets, comets and asteroids revolve around it. This is called heliocentrism. Secondly, our solar system is just one of a billion star systems in the Milky Way galaxy, all of which are slowly rotating around our galaxy’s center. Beyond that our galaxy is merely one of billions of other galaxies, most of which also contain billions of stars each.

Here is a well written article from Discover Magazine about why geocentrism is wrong, and the fundamental flaw in logic that geo centrists make

Geocentrism? Seriously? Discover Magazine

It is a common error to misunderstand Einstein’s special theory of relativity. Many people believe it proves that we can never prove that the earth goes around the Sun. Therefore the ancient statements in the Bible and Talmud implying that the earth is the center of the universe are still justified.

But this is wrong on two counts. One, it contains a fundamental misunderstanding of what choosing a frame of reference means. For further discussion of this point, see the link to the essay on Discover Magazine that I posted separately. Secondly, it’s not just a matter of choosing coordinate systems. We have direct observation evidence that it is the earth revolving around the Sun, and not the other way around.

These are subtle effects that were not measured until the 1800s, but they have been confirmed time and again. Direct measurement showing what is the center, and what is not, has been possible for close to 200 years now. This is a well written summary of the evidence for Heliocentrism: Is there a proof that the Earth moves?
