SPACE-TIME is a collection of imaginary models that use the landscape of London to imagine things normally too big to conceive.

The SPACE project uses landmarks within the M25 to create a scaled model of the Solar system with the Sun at its centre represented by a single 4m pod of the London Eye. On that scale, earth is a golf ball 500m away by Big Ben, Jupiter a beach ball 2.6km away at Hyde Park Corner, and Pluto is a pea orbiting up to 25km from the centre, out by Heathrow Airport.

Physical models of the planets scattered around London invite passers by to the website. The models are positioned at various well-known landmarks that their orbit passes through. The website reveals where the rest of the planets are, and enable the user to contemplate the incredible scale of the solar system.

The TIME project turns a walk across Hyde Park into a stroll back through time. The fence on Rotten Row becomes a timeline, with each post, roughly one metre apart, marking the passing of 50 years, or two generations.

Guided by the website, each generation has its own page describing life at the time. The first bollard is 2000, the next is 1950, the 40th bollard goes back to Julius Caesar; the last Ice Age is 240 posts; whilst the last Neanderthals are fittingly 1km away, near the Natural History Museum.

But the website doesn’t stop there. It continues back in time, generation by generation along the A4, to the dawn of Human evolution somewhere near Reading, out past Ireland and across the Atlantic to the age of the Dinosaurs, to California and the first complex life forms, and onwards twice around the globe to the beginning of Earth itself.

About Guerilla Science – My original idea was to make scale models of the planets to leave in my local park – Hampstead Heath – in the dead of night, and then watch what happens. Then a friend suggested that it should have its own website. So I started learning to code...
