On Question #514. (How do you hold the lulav in space where there is no gravity or only artificial gravity on a space station?).

Q. Although it is gratifying to live in the same generation as a Rav who is as aware of the Shvili D’Rokia as he is of the paths of Torah, and I therefore see the importance of, L’Maan HoEmes, pointing out the scientific error of the questioner, I fail to see the relevancy of gravity to Derech G’diloson.

A. Gravity is after all the natural force that keeps all things on the ground and has to be surmounted for the plants to grow in an upward direction; therefore it defines the way of growth and what we regard as up or down.
