“There is no way for us to see what the Pillars of Creation — or anything in the universe — look like now. We see galaxies 3 billion light-years away as they looked 3 billion years ago. We see the Sun as it looked 8.5 minutes ago. If you were standing one foot in front of me, I would see you as you looked 1.01670336 nanoseconds ago, which is the time it would take for the light to reflect from your face to my pupil. While our brains live in their present, we see everything else in its past tense.”
I wonder is that why we’re so prone to nostalgia, rather than living in the present, or looking ahead?
