In our interconnected world, novel technology could empower just one fanatic, or some weirdo with a mindset of those who now design computer viruses, to trigger some kind of disaster. Indeed, catastrophe could arise simply from technical misadventure – error rather than terror. Martin Rees Read Quote
Some global hazards are insidious. They stem from pressure on energy supplies, food, water and other natural resources. And they will be aggravated as the population rises to a projected nine billion by mid-century, and by the effects of climate change. An ‘ecological shock’ could irreversibly degrade our environment. Martin Rees Read Quote
We know too little about how life began on Earth to lay confident odds. It may have involved a fluke so rare that it happened only once in the entire galaxy. On the other hand, it may have been almost inevitable, given the right environment. Martin Rees Read Quote
It’s often better to read first-rate science fiction than second-rate science – it’s far more stimulating, and perhaps no more likely to be wrong. Martin Rees Read Quote
The images of Earth’s delicate biosphere, contrasting with the sterile moonscape where the astronauts left their footsteps, have become iconic for environmentalists: these may indeed be the Apollo programme’s most enduring legacy. Martin Rees Read Quote
It is foolish to claim, as some do, that emigration into space offers a long-term escape from Earth’s problems. Nowhere in our solar system offers an environment even as clement as the Antarctic or the top of Everest. Martin Rees Read Quote
The Swedish engineer who invented the zip fastener made a greater intellectual leap than many scientists do in a lifetime. Martin Rees Read Quote
Stars that become supernovae start off at least eight times heavier than our sun. They’re so short-lived that, even if they have planets, there is unlikely to be time for life to get started. The surface is 40,000C and, as a result, the colouring will be extremely blue. Martin Rees Read Quote
And we should keep our minds open, or at least ajar, to concepts on the fringe of science fiction. Flaky American futurologists aren’t always wrong. They remind us that a superintelligent machine is the last instrument that humans may ever design – the machine will itself take over in making further steps. Martin Rees Read Quote
To ensure continuing prosperity in the global economy, nothing is more important than the development and application of knowledge and skills. Martin Rees Read Quote
