Professor Russell Stannard (Department of Physical Sciences, The Open University) presents a series with numerous open questions about our consciousness and the physical brain, free will, cosmology and life. Questions such as: What is consciousness? What is free will? What caused the Big Bang? What is time?

One day he says, we will reach the limits of science and it will grind to a halt. Science is the pursuit of knowledge to understand the physical world around us. One day we will reach the boundaries of the knowable. Perhaps we have already reached them. There are questions that we cannot answer and perhaps never will.

The Boundaries of the Knowable

Description: If everything had to be created randomly, the chances of the universe being able to sustain life would be effectively zero. So why is our universe so 'life friendly'? Was it created by an omnipotent being? Are there life forms out in other parallel universes? There could be many 'earth-like' planets out there. Evolution took billions of years on earth. There could be older galaxies out there, where life forms are more advanced than we are, due to the age of their universe.
