100 years ago, the German polar researcher, geophysicist, and climate scientist Alfred Wegener coined the word Pangea to describe the ancient supercontinent that formed 335 million years ago as part of his revolutionary theory of continental drift, for which he was derided for decades before it became the pillar of our geologic understanding of our own planet. 

Italian artist and architect Massimo Pietrobon performs a terrestrial spacetime warp to map modern-day country territories onto the supercontinent 175 million years after it began breaking up – a pleasantly disquieting reminder that we live in a world of ephemeral realities, imaginary and negotiated, mapped onto a physical world that is just as ephemeral on the appropriate timescale.
