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.

Today Phil helps keep you from ticking off an astronomer in your life by making sure you know the difference between a meteor, meteorite, and meteoroid. When the Earth plows through the stream emitted by a comet we get a meteor shower. Meteors burn up about 100 km above the Earth, but some survive to hit the ground. Most of these meteorites are rocky, some are metallic, and a few are a mix of the two. Very big meteorites can be a very big problem, but there are plans in the works to prevent us from going the way of the dinosaurs.

Where and how are we going into space post Space Shuttle? Further travel in space is inhibited by the challenges of gravity wells and the science and cost of developing vehicles that can transcend them. How can the moon possibly help with this problem and move space exploration to the next level?

Ideas about time and space are explored in the changes that constellations undergo over time, the redshift and blue shift measured in interstellar objects, time dilation in Albert Einstein's theory of relativity, the designs of both Leonardo da Vinci and spacecraft that could travel near light speed, time travel and its hypothetical effects on human history, the origins of the Solar System, the history of life, and the immensity of space. In Cosmos Update, the idea of faster-than-light travel by wormholes (researched by Kip Thorne and shown in Sagan’s novel Contact) is discussed.
