What would the universe look like if you were a billion times smaller or a billion times bigger? In this mind-bending series, Jim Al-Khalili will look at the universe across its vast range of size, ranging from the tiniest objects measuring just a few atoms, to vast structures consisting of hundreds of thousands of interconnected galaxies. Investigating these astonishing objects will reveal fundamental truths about our universe.
