Through the Wormhole with Morgan Freeman

Mankind longs for proof that we are not alone in the universe, but first contact will mean the end of the world as we know it. Whether that is a bad thing for humanity or the start of a great future is the subject of much debate.

Given the incendiary history of the topic of racial superiority, it is difficult to ask whether races are as different on the inside as the outside. The answer to this question may tell us where humanity is headed.

The cosmos may be a superorganism: a collection of separate bodies acting like a single being. Scientists are probing this colossal creature for its beating heart, quantum-computing brain and even its offspring.

Even though our ideas and outer appearance change, we carry an overall identity as we move through life. Scientists investigate whether we are born with a core sense of self or if our identities can be altered by our experiences.

Scientists look to quantum mechanics for answers about whether there can be such a thing as nothing. Their work may uncover what our cosmos is made of, how it came from nothing and when it might collapse again into an empty void.

Resurrecting bodies isn't enough -- to truly live again, we must also resurrect our minds. Scientists are developing ways to digitally preserve the contents of our brains. We may rise again as software, embedded in new forms.

Researchers are uncovering the hidden forces that inflame our inner demons, looking for ways to neutralize the source of evil in the brain. Methods include learning impulse control and stimulating altruism.

The subconscious has long been thought of as the source of our primal fears and desires, but scientists have discovered how the subconscious makes snap decisions that protect us from harm and how it can heal our bodies of disease.

Eternity is an idea humans have wrestled with for thousands of years, and scientists are exploring many different theories about whether time will tick on forever or if time itself will come to an end.

Scientists are crossing new frontiers to find out how humans experience God. Neuroscientists are recreating out-of-body experiences in virtual reality laboratories to uncover what happens to the brain during spiritual journeys.
