Is Time Travel Impossible?

Season 5 Episode 37 | 12m 33s Video has closed captioning.

Time travel stories are cool because both the past and future are somehow more interesting that the present and because everyone wants a redo. But so far it appears we’re doomed to live consumed by regret in the eternal, boring present. Time marches on, inexorably and only forward. Or so we thought until Einstein came along.
