Through the Wormhole

Is There Life After Death?
Science is a long way from answering the question posed in this program. But exploring it has proved a fertile avenue for investigation into what exactly is consciousness and self-awareness.

Is There an Edge to the Universe?
To the average person it seems obvious that the universe must have an edge. Yet most cosmologists think that like a ball, or more likely a bagel, the universe has no end, other then a temporal one - a beginning and, perhaps, an end. But several scientists agree with the common man that there is an edge to the universe and they have some definite ideas about what is beyond the edge and how to prove their case.

Does Time Really Exist?
After a brief explanation of how we measure time this program takes a detailed look at how we perceive time. Then it's time for the physicists to present their ideas about what time is before Steve Weinstein talks about two dimensional time.

Are There More Than 3 Dimensions?
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.

Is There a Sixth Sense?
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.

Are There Parallel Universes?
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.

How Does the Universe Work?
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.
7.9 /10
Can We Travel Faster Than Light?
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.

Can We Live Forever?
This program reviews current thinking about what causes death and aging. Then it examines increasingly bizarre ideas about how to prevent them.
7.6 /10
What Do Aliens Look Like?
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.
