Through the Wormhole - Season 2 (2011)

To scientists it looks like the weakness of gravity, the existence of dark matter and the big bang may all be dependent on how many dimensions there are to the universe. But are the three dimensions we're used to too few or too many? This program examines the pet theories of several scientists about the dimensionality of our universe, how they are going about proving their theories and why their theories don't agree with the three dimensions that seem obvious to us.

Several scientists have conducted experiments, although with somewhat questionable controls, that suggest humans may have a rudimentary capabilities for telepathy and precognition. This program reviews the studies and the scientists speculate about how these capabilities may work and why we might have them.

This program presents the scientific foundation for parallel universes. Then it reviews the various speculative ideas scientists are exploring about how universes form and how they interact. In our explorations we bump into our old cosmic friends; black holes, white holes, dark matter and the big bang.

A revolution in science is underway that will transform life on Earth and ensure our survival as a species. If we can solve the equation of everything, it will present the keys to creation itself.

The laws of physics allow a variety of ways to get around the universe faster than the speed of light. These prospects are explained along with the daunting engineering challenges of making them practical and safe.

This program reviews current thinking about what causes death and aging. Then it examines increasingly bizarre ideas about how to prevent them.

This program gives serious consideration to what life forms on other planets might look like founded on the vast diversity of life on earth now and in the past and what is now known about the environments on other planets found by the Kepler telescope. Then it indulges in a little speculation about what extra-terrestrial intelligence might be like.
