By the Grace of G-d5th of Tevet, 5734Brooklyn, N.Y.

Greeting and Blessing:

Your letter has just been received, in which you write about your research in the theory of relativity, etc.

It is evident from your letter that you are aware of the prevailing climate among scientists involved in this field, and the difficulties of introducing innovations into this area, notwithstanding the fact that recently some details of the theory have been challenged with support from observations in astronomy - of which you must also be aware.

To be sure, the dispute has not been resolved yet, but apparently the controversy is over some details, while the basic background of the theory has not been refuted.

In light of the above, anyone who would attempt to introduce a radical change or new concept in this field would require personal contact with prominent scientists involved with the relativity theory. The logical way for you to get such contact would be, I believe, through faculty members of a university in your vicinity. I must add, however, that I am not very optimistic about your being able to get such a contact easily. Nevertheless, one can never know without trying.

May I volunteer a further remark, which no doubt must have occurred also to you. When approaching hard-core scientists, I do not think it will impress them to mention about an inner voice, and the like, which would only make them prejudicial and skeptical about the scientific value of your theory.

Inasmuch as everything is by hashgachah pratit, I want to take advantage of this opportunity to express the hope that since you are permeated with the idea of finding the underlying principle that unifies the physical universe, be it background ether which you mention, or anything else, it must directly strengthen the basic concept of One G-d, as we declare twice daily: Shema Yisroel, Hashem Elokkeinu, Hashem Echod. For the true and inner concept of it is not that there is only one deity, but that there is one reality, namely G-d, from Whom all existence derives; hence there must be an underlying unity in all the diversity of the universe.

Moreover, since the physical world can be comprehended only through its material and physical forces, from which all research must begin, so also in the metaphysical world, more specifically - in the world of Torah and mitzvot, “the essential thing is the deed,” namely, the actual fulfillment of mitzvot, which must precede all inquiry into emunot v'deot, beliefs and opinions, or, as our Sages expressed it succinctly naaseh must come before v'nishma.

With blessing,
