Let’s Begin…
The universe: is it everything, things we can see, or things that have existed and will one day exist? Or, perhaps it's all of the above. Whatever your conviction, the universe is here to stay...or is it?

How did the universe begin -- and how is it expanding? CERN physicist Tom Whyntie shows how cosmologists and particle physicists explore these questions by replicating the heat, energy, and activity of the first few seconds of our universe, from right after the Big Bang.
The atoms around you have existed for billions of years -- and most originated in the flaming, gaseous core of a star. Dennis Wildfogel tells the captivating tale of these atoms' long journeys from the Big Bang to the molecules they form today.
The shape, contents and future of the universe are all intricately related. We know that it’s mostly flat; we know that it’s made up of baryonic matter (like stars and planets), but mostly dark matter and dark energy; and we know that it’s expanding constantly, so that all stars will eventually burn out into a cold nothingness. Renée Hlozek expands on the beauty of this dark ending.
