My woodshop teacher, who is a physics hobbyist, insists that by using magnitism to stretch time, we could travel faster than light. I protested at the idea; but my explanations of how time doesn't matter much when it comes to ftl travel, and the fact that you need infinite energy failed to convince him. Besides, I don't see how 'stretching time' could allow for ftl travel. To prove his hypothesis, he took one step, and claimed he traveled faster than light. Can anyone make sense out of this??
