Size Matters

Why are insects small and planets big? Why is Earth not the size of Jupiter, or why aren’t people the size of mice? And what would happen if we changed all that? This larger-than-life two-part special will show that when it comes to the universe, size really does matter. We’ll take the audience to a series of parallel worlds where size can be changed, and in so doing, we’ll answer the biggest (and the smallest) questions in the universe in the most unforgettable way. Size Matters explores a fascinating web of scientific concepts to uncover not just why things are as they are, but why they could never be any different. Along the way, we’ll discover why the sun and the planets are the size they are, how insects could one day be gigantic, how big the biggest building could be and how a tiny human would be almost superhuman!
