Through the Wormhole - Season 3 (2012)

What is it that gives each one of us a unique identity? As we move through life our outer appearances transform almost entirely. Our opinions and ideas change. Are we all born with a permanent sense of self or can our identities be altered?

Can there be such a thing as nothing? Scientists are looking for answers in the mind-bending science of Quantum Mechanics. Their work may uncover what our cosmos is made of, how it came from nothing and when it might collapse into an empty void again.

What if death wasn't the end? 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. But can psychopaths who lack empathy be helped?

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 that it can be trained to actually heal our bodies of disease.

Can time tick on forever or will time itself end? It's possible that eternity already exists, and the future is traveling back in time to shape the present. Or time might even be a holographic projection, reaching back to us from the end of eternity!

Did God invent humanity? Or did we invent God? Since our brains are where we experience reality, does imagining God make God real? One neuroscientist is trying to find the answer by peering into the human mind, and seeing what God really looks like!
