Trying to imagine the smallest things in our universe is rather difficult. Quarks, cosmic strings, neutrinos. The sale of the truly tiny is simply beyond our realm of comprehension. Similarly, it’s hard to conceive of the largest things in the cosmos — supermassive black holes that swallow entire systems, large quasar groups that span galaxies, and on and on.

So, it’s not too surprising that simultaneously imagining the smallest of the small and the largest of the large is a mind-bendingly difficult task. How does a subatomic particle that pops into existence compare to a black hole that’s 10 billion solar masses?

Fortunately, the people at Number Sleuth have created an interactive graphic that lets you do just that. There, you can compare the world of the very time with that of the very large — sliding all the way from the nucleus of a hydrogen atom to the scale of the observable universe.
