When you think about all the things out in the Universe, you might imagine something like giant galaxy clusters or immense black holes. Or maybe you picture something smaller (but still huge) like individual stars. But what about on the other end of the spectrum? What is the smallest thing in the Universe? Photons? Gluons? 

In the latest Talk Nerdy To Me video, Jacqueline Howard visits the Fermi National Accelerator Laboratory in Illinois to find out how scientists are exploring the tiniest things in the Universe. How do these particle physicists study things like bosons which are 0.0000000000000000001 meters in length.
