A conversation from one of yesterday's classes, wherein we watched the Cosmos revival episode "Deeper, Deeper, Deeper Still":
“So Mr. Pariah, the video said that light takes time to travel, so when we look out into space, we’re looking back in time?” “That's right.” “So if we could travel faster than light and then look back at the Earth, would we see the Earth’s past?” “Yes, we would.” “Whoa. That is so cool!”
I love conversations like this.
