The scale of the Universe

The Scale of the Universe 2 is an interactive Powers of Ten that takes you from the Planck length all the way up to the size of the observable Universe. That’s more than 60 orders of magnitude! Also interesting that the smallest things (Planck length, strings, branes) are millions of times smaller compared to human scale than the observable Universe is larger. Plenty of room at the bottom indeed.
