The Planetary Portals Collective is a creative research group formed by Casper Laing Ebbensgaard, Kerry Holden, Michael Salu, and Kathryn Yusoff. They use imperial archives to create critical cartographies of the colonial praxis of "emergence and extraction" and their work enacts a speculative reworking of the trade and trauma produced by geoengineering a colonial continent. Paying attention to the resident ghosts of the colonial archive, they seek to work with the alterable possibility of life against the calculative geometrics of diamond power and capital, against acts of British colonial imagination violently mapped over occupied ancestral lands.
