Lab imitations of the unobservable cosmos can be genuinely insightful

Despite the obvious caveats, physicists are right to use fluids and other physical analogues to search for fresh insights about extreme cosmic phenomena, from black holes to the big bang

A dense collection of stars covers the view. Towards the centre the stars become even more dense in a circular region, and also more blue. Around the edges there are some redder foreground stars, and many small stars in the background.

NEW CLOUDS ABOVE US The modern world relies on satellites for its communications and commerce. While mostly invisible to us as we go about out daily lives, our entire modern way of living ? both socially and professionally ? is intimately linked with the orbital space around the Earth. How we treat this extraterrestrial environment will determine how much we can rely on it in the future. ?In this view of Greenwich, London, you?ve got examples of what?s in space. I photographed about 300 artefacts ranging from satellites to rocket bodies, satellite parts, solar panels, all the way down to the screws and a glove to show what?s up there. The photography was done over a one year period, across North America, Europe and the UK. I wanted to show this from a human perspective ? from the ground looking up. I chose Greenwich because of its history of astronomy and because from there you can see the financial district of London to highlight the modern world?s connection to the satellites that circle Earth.?
