Are there cases of time travel in the Torah and ancient Jewish texts? Is it possible that Adam, Enoch, and Moses were able to traverse the universe using faster-than-light technology? And how do we deal with apparent chronological contradictions in the Torah? Find out in this fascinating class, where we also uncover the true meaning of God’s Ineffable Name, propose a theory for how Adam was able to live 930 years, and calculate the speed of God’s divine “chariots”.
For a written summary and lots more information (including the time travel of Eliyahu briefly mentioned in the class), please see here.

As we prepare to usher in a new year, we remember that while our calendar follows lunar months, it is still synchronized to the sun over the course of a 19-year cycle. Since a lunar month is 29.5 days, each month on the Hebrew calendar is either 29 or 30 days, resulting in a year that is typically just 354 days long. The solar year is a bit over 365 days long, meaning that a strictly lunar calendar will fall behind 11 days each year. To avoid this problem, we add an entire leap month, a second Adar, seven times in 19 years. This ensures that we stay in synch with both moon and sun. The upcoming year will be such a leap year, with 13 months instead of 12.
