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.
