Scenario: Grey Goo

The components that make up our computers are constantly getting smaller, allowing more and more processing power to be contained in smaller and smaller devices. The transistors that make up a modern computer chip have features as small as 25 nanometers. At the same time, we are discovering how substances behave at the sub-microsopic level, enabling us to design materials with a range of innovative and useful properties. These technologies could be adapted to make ultra-small machines capable of performing useful tasks, such as delivering medicines to specific parts of the body, sensing and reporting on hard-to-reach environments, or manufacturing new devices from raw materials. This last ability could lead to a self-replicating nano-device, able to create components from any suitable source and assemble them into a working copy of itself. Such a device, if left unchecked, could multiply extremely rapidly until all available resources had been consumed and turned into more nano-robots - the result might appear to the naked eye as an amorphous mass, and this is therefore known as a 'grey goo' scenario. Self-replicating nano-machines, once started, would be practically impossible to stop.

We have had to estimate certain contributory factors to the EOTWAWKI events, and the timings may not be 100% accurate. We can not accept responsibility for any loss or inconvenience that may arise should the world end earlier than indicated, or if it should fail to end when anticipated.
