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.

There's been some research in cognitive science, I'm told, that discloses that there have always been perhaps 10 to 15 percent of people who are, as Pascal puts it, so made that they cannot believe. To us, when people talk about faith, it's white noise.

There is a history of thinking about space science from an environmental ethics perspective. And part of what I want to do is turn that back and use that experience to see if it reflects how we think about the Earth.

I was always fascinated by engineering. Maybe it was an attempt maybe to get my father's respect or interest, or maybe it was just a genetic love of technology, but I was always trying to build things.

The Internet challenges traditional ways of distributing and processing information and so encourages new standards and behavior.
