Cool demonstration of the full scale of the Universe

The full scale of the Universe traverses the sizes as small as one Planck Length (hypothetically the size of quantum strings, branes and foam), all the way up to the distance to the farthest galaxies (and a bit beyond).  A project called “The Scale of the Universe 2” by Cary Huang helps put all of ths into perspective.  Differences in sizes between different elements of the world around us is a bit surprizing.  In particular, check out the size comparison between an ant and the largest bacteria.

 

The web tool doesn’t just show examples at each scale.  It also provides a brief summary or explanation of every object when you click on it.
