"Death of the Universe" takes viewers on an incredible journey through the cosmos in search of answers about how it is all going to end. Three theories about the universe's fate come to life as the program explores the battle between dark matter and dark energy, the forces that will determine whether the cosmos will collapse, freeze, or rip to oblivion. Spectacular never-before-seen graphics help explain the principles behind each theory, and backyard examples make some of the most complex scientific questions ever asked accessible to the viewing audience. In the end, viewers are provided with a greater understanding of where our universe has been, and what the fate of everything we know could entail. In the farthest reaches of space, a volatile battle is taking place between two forces so great, they may eventually destroy the very universe itself. Known as Dark Matter and Dark Energy, these opposing forces have the capacity to rip apart the universe atom-by-atom. While scientists have previously theorised about a "Big Crunch" where the universe retracts back to its original size, the discovery of Dark Matter and Dark Energy has placed that hypothesis on the backburner. Some astronomers now believe that if Dark Matter offsets Dark Energy then as the universe slowly expands, stars will gradually fade, running out of fuel and leading to a dark, cold and lifeless universe. Others hypothesise a much more violent end where Dark Energy continues to expand the universe at a greater and greater speed. Stronger than gravity, Dark Energy would pull apart everything down to the fundamental particles - the universe's very fibres. While the universe's end may be 50 billion years away, great leaps in science will continue to alter how we believe the universe was formed - and how it will end.
