Discovery Channel - How the Universe Works Series 3 (2014) Part 9 The Search for a Second Earth
How the Universe Works: Series 3
The universe is made up of wondrous statistics that detail the incredible range between large and small, near and far, and light and dark – but what any of these inexact terms really describe is still open to debate. We are surrounded by laws that govern everything – determining the colour of the stars, the gravity controlling our solar system and the beginning and end of the universe itself. Want to know how the universe started and how it will end – and everything in between – with such luminaries as Stephen Hawking and Michio Kaku? Watch How The Universe Works.
