Hare Krishna! I am hoping someone who is well versed in the Vedas (or any Veda) will answer this question. Though all comments are ofcourse wolcome. Sayana, in his commentary on one of the verses in the Rig Veda, states the speed of light. How does he arrive at this? Also, slightly away from this topic - How did archeologists put a date on the Rig Veda? Thank you Hare Krishna! MohanKrishna
