How Does The Nucleus Hold Together?

Season 9 Episode 5 | 14m 28s  | Video has closed captioning.

Two protons next to each other in an atomic nucleus are repelling each other electromagnetically with enough force to lift a medium-sized labradoodle off the ground. Release this energy and you have a nuclear explosion. So how does it all hold together? Nuclei are held together by a quirk of nature, without which we would have no complex atoms, no chemistry, and certainly no labradoodles.
