The Big Bang gave birth to our universe. But what will bring it to an absolute end? In 21 minutes, a mere mega blip of time, this episode of Cosmic Journeys offers an impressive visual account of this big enchilada question, taking you across trillions of years. The sun will die but make the earth uninhabitable well beforehand. A similar process of decay will play itself out across the universe and we will enter the "degenerate era." Dark energy, dead stars, and black holes will reign supreme. But what will happen in the very, very end, when the cosmic clock strikes a number known as a "googol" or some time thereafter? A lot of that will get sorted out by the work physicists are now doing with the Large Hadron Collider, the giant particle accelerator located near Geneva, Switzerland. Give the video a little bit of time. The second half gives you the goods.
