I just wanted to share this with you, because it's pretty awesome. It's an interactive scale of objects in the universe, all the way from theoretical strings up to the estimated size of the universe.
Scale of the universe 2
Some of my favourite facts so far:
-The diameter of a cofee bean is 10-29 of the known universe
-The USA is bigger than pluto
-A minecraft world is bigger than neptune
-The outside of the universe is filled with a low resolution JPEG of static noise
I hope you find this useful if you've yet to see this.
