How Small Is the Universe?

Episode 5 of 18

Series exploring scientific issues. Following the search for the smallest thing in the universe, a journey where things don't just become smaller - but also a whole lot weirder.

Horizon plunges down the biggest rabbit-hole in history in search of the smallest thing in the universe.

It is a journey where things don't just become smaller but also a whole lot weirder. Scientists hope to catch a glimpse of miniature black holes, multiple dimensions and even parallel universes. As they start to explore this wonderland, where nothing is quite what it seems, they may have to rewrite the fundamental laws of time and space.
