Perhaps the best motivation for going to Mars is political. It is obvious that no single nation currently has either the will or the resources to do it alone, but a consortium of nations and space agencies could achieve it within 20 years. – Paul Davies
The origin of life is one of the great outstanding mysteries of science. – Paul Davies
A permanent base on Mars would have a number of advantages beyond being a bonanza for planetary science and geology. If, as some evidence suggests, exotic micro-organisms have arisen independently of terrestrial life, studying them could revolutionise biology, medicine and biotechnology. – Paul Davies
Man-made computers are limited in their performance by finite processing speed and memory. So, too, the cosmic computer is limited in power by its age and the finite speed of light. – Paul Davies
The biggest opportunity in 2013 is in Africa. It has seven out of the ten fastest-growing economies in the world. In Nigeria alone there are 100 million people with mobile phones. In total, 300 million Africans – five times the population of Britain – are in the middle class. – David Miliband
