A different kind of string theory here, with two geniuses Siena Stubbs and David Turnbull, running some thought experiments and yarns to answer the question, 'What is real?' Siena Mayutu Wurmarri Stubbs is a photographer, a young Yolŋu woman of the Gumatj clan of the Yirritja moiety. Her homeland is Buwaka. David Turnbull is a retired scholar whose work has been an inspiration for a lot of thinking around spatial cognition in our lab. He says that science is an Atlas. Yeah, it's like that. Get ready for a fast ride around the universe. If you want more of David's work, check out this generous online publication: http://territories.indigenousknowledge.org/
