Planet Earth shrinks to half size causing altitude sickness and a cosmic disaster, the sun gets as small as a sun can be, turning Earth into a frozen mud ball. We also see what happens to a man who shrinks to the same size as a wasp.
Planet Earth grows to outlandish proportions that causes lying down to become the new standing up, the sun gets big ideas giving us a 20,000-year winter before blowing up in the biggest explosion since the big bang, we meet a dog the size of a dinosaur and Joe himself turns into a 49ft giant.

Helen Czerski ventures beyond the visible spectrum in the final (and best) episode in this vibrant little series, showing how electromagnetic radiation is so much broader than the narrow slice of reality we see with our eyes. Before delving into the details of UV, infrared and x-rays, Dr Czerski explores colour subjectivity by trying on a dress that recently divided the internet — to some it appeared blue and black, to others white and gold. It's a perfect fit. It's also a neat analogy of how people can have opposing views but both swear blind that their perspective is correct. The series ends with some amazing imaging techniques that show our bodies in a whole new light.
One of the most amazing facts in physics is that everything in the universe, from light to electrons to atoms, behaves like both a particle and a wave at the same time. But how did physicists arrive at this mind-boggling conclusion?
Early Earth was a canvas for the vast new palette of the colours of life, with the diversity of human skin tones telling the story of how humanity spread and ultimately conquered the planet. Dr Helen Czerski explores the true masters of colour - which are often the smallest and most elusive - travelling to the mountains of Tennessee to witness the colourful mating display of fireflies, and revealing the marine creatures that can change the colour of their skin in order to hide from the world.
