The Universe: 10 Ways to Destroy the Earth
Don't try this at home! In this episode, our experts cook up ten ways you
could destroy the earth, including: swallowing it with a microscopic black
hole; blowing it up with anti-matter; hurling it into the Sun, and switching
off gravity. This is a fun way to explore the dangerous physics of the
Universe and the properties of the planet we call home.
