Post-human intelligence will develop hypercomputers with the processing power to simulate living things - even entire worlds. Perhaps advanced beings could use hypercomputers to surpass the best 'special effects' in movies or computer games so vastly that they could simulate a world, fully, as complex as the one we perceive ourselves to be in.

As regards my own 'philosophy,' I continue to be inspired by the music, liturgy and architectural tradition of the Anglican Church in which I was brought up. No one can fail to be uplifted by great cathedrals - such as that at Ely, near my home in Cambridge.

Some of the 'aha' insights that scientists strive for may have to await the emergence of post-human intellects.

To most people in the U.K., indeed throughout Western Europe, space exploration is primarily perceived as 'what NASA does'. This perception is - in many respects - a valid one. Superpower rivalry during the Cold War ramped up U.S. and Soviet space efforts to a scale that Western Europe had no motive to match.

I'm not talking about what you hear from 5 per cent of the population on the radio, in the papers. I don't pay attention to it. I travel around the country. I'm happy I have a good relationship with the people.

I didn't do very well when I was at school, so my dad gave me the opportunity to travel in Africa. I drove from London to Nairobi. It was incredible.

So for me, it can be theatre or being in L.A. or in some other part of the world, as long as I can explore storytelling and human connection through storytelling, I'm quite content.

My bucket list tends to relate to travel or eating.
