Question:
Dear Rabbi,
What do you say in halacha if a man is on the moon when you commemorate a new moon?
I would like to hear your thoughts.
Answer:
Hello,
These are only thoughts, and if and when it will be a real question, it should be posed to the great scholars of the generation. In theory though, I would say , that commemorating the new moon is an idea, that the Jewish people who are compared to the moon, which wans and then grows back again, so too the Jewish people will go though galut, and then get stronger again during the time of Moshiach. The time of the new moon also helps us calculate the exact date of the festivals. Therefore even a person on the moon would celebrate the new moon, and Rosh Chodesh.
Best wishes
