The universe is fascinating. It's sheer scale makes it's almost impossible to comprehend. Back when I completed my teaching certification, I used to show this video to students at various times - there's no better way to blow their minds to the 'massiveness' of it all.
DaringFireball linked to the video below yesterday. It's 45 minutes long so not as easy to view as the one above but fascinating - a real-time view of how light moves from the sun out into the universe. Wow.
Getting sucked into the minutiae of life can be easy but keeping perspective in the grand scheme of things, we're a blip on a blip!
