an interactive & quite extensive size comparison of the perception of our universe. Universcale starts from a proton (1 femtometer) goes over to a hydrogen atom (100 picometers), a protein nanometer (10 nanometer), & a red blood cell (7-8 micrometer), & ends at the moon (3,764km), a nebula (30 light years), & finally at the outer limits of our universe (13,7 billion light years).
