How big can we go? How small can we go?

Imagine what the world would look like if you were the size of a bed bug. Even household objects look unrecognisable magnified 300 times their normal size. With our human eyes we can see objects as small as millimetres and as large as kilometres, but how do we see things even smaller and even larger than that?

Join engineers Jamie Gallagher and Sophie Robinson as they demonstrate some of the science and engineering that allows us to see microscopic objects and gigantic galaxies.
