Everyone from the most simple-minded to the deepest thinking has pondered a question that strikes at the core of our existence: Is there life after death? What happens to the soul after we die? People who have had near-death experiences claim to have visited the other side before getting yanked back into consciousness. Now, some of the brightest minds in science are trying to understand how life can persist beyond the physical and what will it look like. It might be a quantum state based on the fundamental laws of the universe. Ultimately, it is a journey that struggles to decode the most complicated instrument in the universe: the human brain.

A major new series exploring the wildlife of South America. This is a breathtaking aerial journey through the most spectacular locations on the continent, from the icy peaks of the Andes to the Amazon jungle and the Atacama desert. These extreme conditions are home to a mind-boggling variety of creatures, many of them rarely seen before on television.

Push the limits of your imagination as astronomers attempt to grasp the mind-boggling extremes of size, distance and speed within our universe by bringing them down to earth. In this episode, our cast uses awesome analogies to bring the biggest objects, farthest distances and fastest speeds down to earth. To truly understand the scale of the cosmos, we jump behind the wheel of monster trucks, scale the Golden Gate Bridge, and race across the desert in a rocket-powered car.

Located in an almost inaccessible chamber deep in a South African cave, the site required recruiting a special team of experts slender enough to wriggle down a vertical, pitch-dark, seven-inch-wide passage. Most fossil discoveries of human relatives consist of just a handful of bones. But down in this hidden chamber, the team uncovered an unprecedented trove—so far, over 1,500 bones—with the potential to rewrite the story of our origins". They may help fill in a crucial gap in the fossil record and tell us how Homo, the first member of the human family, emerged from ape-like ancestors like the famous Lucy. But how did hundreds of bones end up in the remote chamber? The experts are considering every mind-boggling possibility. Join us on the treacherous descent into this cave of spectacular and enigmatic finds, and discover their startling implications for the saga of what made us human.

Professor Richard Dawkins explain how his unique scientific perspectives have redefined how we think about the world around us and describe his big moment or discovery. Dawkins reveals how he came to write The Selfish Gene in 1976, an explosive book which divided the scientific community and made him the most influential evolutionary biologist of his generation, and how this made him an outspoken spokesman for atheism.

The Pythagorian philosopher Plato hinted enigmatically that there was a golden key that unified all of the mysteries of the universe. It is this golden key that we will return to time and again throughout our exploration. The golden key is the intelligence of the logos, the source of the primordial om. One could say that it is the mind of God. With our limited senses we are observing only the outer manifestation of the hidden mechanics of self similarity. The source of this divine symmetry is the greatest mystery of our existence.
