I'm fascinated by the scale of things. I remember a video back in high school that they showed during science class that demonstrated the scale of the universe. It started with a couple having a picnic in the park and the camera backed away to eventually end up at the edge of the known universe. Then the camera fell back down to the starting point and went microscopic to show the nucleus of an atom. I've seen updated versions but none as impactful as that one seen by a very young me. Now this comes along to show how deep the oceans are and it's pretty cool too. Enjoy!
