Professor Brian Cox probes our moment of creation. How did our Universe come into existence? Was there a time before the Big Bang? Do our laws of physics inexorably lead to the existence of us?
Professor Brian Cox tells the biggest story of them all. Inspired by the Southern Sky as he travels Australia, Brian reveals our very latest understanding about how the Universe began & how it will end.

From the furthest reaches of space to our own cosmic backyard, we count down the discoveries that changed everything we know about our universe.
S5E1 • How the Universe Works • 2016 • Astronomy
This episode concentrates on how the universe was made in the Big Bang and how scientists predict it could end similarly as it continues to expand. Several theories are covered including the "Big Crunch" where the universe shrinks back to its original size, and the "Big Chill" with the universe slowly freezing to death.

How do astronomers make sense out of the vastness of space? How do they study things so far away? Today Phil talks about distances, going back to early astronomy. Ancient Greeks were able to find the size of the Earth, and from that the distance to and the sizes of the Moon and Sun. Once the Earth/Sun distance was found, parallax was used to find the distance to nearby stars, and that was bootstrapped using brightness to determine the distances to much farther stars.
