By Kesava Krsna DasaThe famed Time Machine is now a serious inevitability, according to many. One scientist says that he wants to go back to the past to see his deceased father and possibly help him with present-day medicine.If Krishna says that He is Time and is the destroyer of all things, including our karma, then what type of power or technology can oppose this? Going back into the past means to undo karma and to undo history.
