Rabbi Ezagui's YouTube podcast, 'Physics of the Mystics,' explores the intersection of scientific discoveries and ancient Jewish wisdom. This particular episode examines the nature of light, drawing parallels between its characteristics, as described by Einstein's theory of relativity, and the timelessness of God. The discussion explains how the constant speed of light leads to the relativity of time, suggesting that at the speed of light, time essentially stops. This concept is then connected to the theological idea that God exists outside of time, experiencing all moments simultaneously. Ezagui aims to use scientific understanding to enhance appreciation for the attributes of God as described in the Torah and Jewish mystical texts. He also mentions his books and an upcoming listener raffle.
