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.

It seems so antithetical to the teachings of Christ to proclaim your faith in public. I mean, of course you're not supposed to hide your light under a bushel.

I just take every day on faith.

We are constantly learning and growing and changing. We are really an experiment. We are endeavoring to discover if a community of faith can exist purely for the good of others.

We have to make it easier to afford to go into education in the first place, so you don't leave with crippling debt that you never have a chance to pay back because you're not making enough money.
