Proximate Cause

Right now, we are moving approximately 100,000 kilometres per hour around the Sun. It would seem like an incomprehensible speed to most, yet compared to the pace of the everyday modern condition of ‘progress despite all odds’ it pales into insignificance by comparison. As this modern lifestyle continues to urge us onward, faster and faster, we as humans are finding it harder to stop and remember that we are part of the natural world and are subject to all that nature has to offer us.

This new video landscape experiment looks outward and inward simultaneously. The audio, though it sounds like an abstract breeze, is a sound originating from the edge of our Solar System – The Heliopause. Heliospheric 2-3 kHz radio emissions are produced when an interplanetary shock interacts with the Heliopause, which is the boundary between the solar wind and the interstellar plasma.

Although the wind in our own sky and the solar wind are not of the same origin, just as the forest sways in our breeze here on earth, the solar system also sways in its own gentle motion of energy – reminding us of our own relative insignificance and fragility.
