Ptolemy vs. Copernicus?
A New York doctor promises Rabbi Feivel Rimmler, of Brighton Beach, to take on Shabbos, Family Purity, tefillin, and to influence others on one condition: the Rebbe openly states his belief that the earth revolves around the sun. Will the Solar System prove the Rebbe a “wise man” or a “fool?” The Avner Institute presents an elegant exchange of letters where the Rebbe firmly takes up the challenge with a geocentric view that is solidly grounded in contemporary science and, most importantly, in Torah thought.
“500 Years behind the Times?”

Dear Rabbi Rimmler,
As per our conversation of today regarding taharat hamishpacha [family purity], etc., I did say to you, and am submitting the same in writing by means of this letter, that if the Rebbe would make a public statement to the effect that he personally believes and directs that his followers therefore believe that, since the Talmud states that the sun revolves around the earth, it is therefore his firm belief that the sun does indeed revolve around the earth, that I will;
Personally observe the laws of taharat hamishpacha, tefillin, and Shabbat, and
Influence as many of my friends and colleagues to do the same.
It is, however, more than obvious to me that the Rebbe will not, in any way, make such a ridiculous statement, because
He does not wish to be labeled as a fool.
He himself is not as foolish as some of his ardent but hypnotized followers.
I predict, with no hesitation, that I will not hear any more about this matter, either from you or from the Rebbe or through the press. I must tell you that I feel a deep personal hurt when people such as you make such asinine, ridiculous statements and then hide your abysmal ignorance behind the façade of “Torah.” Don’t you realize that you can still be believers and not live 500 years behind the times??
“Practical or Scientific?”

Your letter, addressed to Rabbi Feivel Rimmler, reached me with considerable delay, more specifically before last Shabbos.
In view of its content, I naturally take this first opportunity of replying to it.
Not knowing whether you are more interested in the practical implication, and/or in the scientific aspect, I am writing two separate replies, enclosed herewith, which you can read in the order you prefer.
As customary in such a case, I am sending copies of the letters to Rabbi Rimmer, since it was he who conveyed your letter to me, and you will surely not mind.
With esteem and blessing,

P.S. It is surely unnecessary to add – though I am add it for the record – that I take it for granted that you will keep your commitments with regard to the practical aspects of your letter.
“My Firm Belief”
By the Grace of G-d
Rosh Chodesh Kislev 5736

Greeting and Blessing:
In reply to your question relating to the matter of the motion of the sun and the earth, whether the sun revolves around the earth or the earth around the sun.
It is my firm belief that the sun revolves around the earth, as I have also declared publicly on various occasions and in discussion with professors specializing in the field of science.
In view of the above, I have no objection, of course, if you wish to make this view known to whomever you choose, since, as mentioned, I have declared it orally and in writing to correspondents who had inquired into this subject, on more than one occasion.
With esteem and blessing,

P.S. On several of the above-mentioned occasions, when I spoke on the subject publicly, I gave a clear and detailed explanation why this view is in no conflict at all with contemporary science. I emphasized, however, that I was speaking of modern and contemporary science, as it differs from Ptolemaic and medieval science when conflicting views were held on this subject. Modern science, on the other hand, having rejected both systems, has reached conclusions which present no problem to one holding to the belief that the sun revolves around the earth, as I have explained at some length somewhere.
“Fool or Wise Man?”
By the Grace of G-d
Rosh Chodesh Kislev 5736
Brooklyn, NY
Greeting and Blessing:
This is in reply to your inquiry on the question of the rotation of the sun and the earth in relation to each other, namely, whether the sun revolves around the earth, or the earth around the sun, and which view is to be accepted, etc.
I presume you have in mind the scientific view, i.e., what science has to say on this question, and I will address myself to this aspect.
It is well known that this was a controversial issue in ancient and medieval science. However, since about half a century ago, with the introduction of the theory of relativity, the latter has been universally accepted as the basis of modern science. To be sure, in the beginning there were scientists working under the Soviet regime who opposed the relativity theory – for various reasons which need not be reviewed here, but even this opposition fell by the wayside later, so that now all scientists generally accept the theory of relativity as the latest and most plausible scientific system.
One of the conclusions of the theory of relativity is that when there are two systems, or planets, in motion relative to each other – such as the sun and earth in our case – either view, namely, the sun rotating around the earth, or the earth rotating around the sun, has equal validity. Thus, if there are phenomena that cannot be adequately explained on the basis of one of these views, such difficulties have their counterpart also if the opposite view is accepted.
Secondly, the scientific conclusion that both views have equal validity is the result not of any inadequacy of available scientific data, of technological development (measuring instruments, etc.), in which case it could be expected that further scientific and technological advancement might clear up the matter eventually and decide in favor of one or the other view. On the contrary, the conclusion of contemporary science is that regardless of any future scientific advancement, the question as to which is our planetary center, the sun or the earth, must forever remain unresolved, since both views will always have the same scientific validity, as stated.
Thirdly, it follows that anyone declaring that a person who chooses to accept one of these systems in preference to the other is a fool, while one who accepts the other is a wise man – such a judgment shows that the person making it is ignorance of the conclusions of modern science, or that he has not advanced beyond the science of Ptolemy and Copernicus. Obviously, a person not versed in the development of science in the course of the past half-century or so is not qualified to make any judgment pertaining to science.
A further point may be added, though perhaps not directly pertinent to our discussion. It is that every person, including modern scientists, actually has three options to choose from in this matter:
That A revolves around B.
That B revolves around A.
That A and B revolve around each other.
But such a choice cannot be dictated by science; it would be one’s personal choice and belief.
What has been said above is – to repeat – the deduction of the theory of relativity, as it is expounded in various scientific tests, and it can be checked with any scientist who is thoroughly familiar with the said theory. Of course, on the elementary and high school level, science in general, and the so-called Solar System in particular, is taught from relatively simple textbooks, and the change in the scientific attitude towards the subject under discussion is not emphasized. But, as stated, it would be quite simple to verify it with any scientist who knows this particular field.
