String theory, multiverses, the big bang, and inflation theory can be mind-bending concepts to ponder. Dr Brian Greene is a science communicator and professor of physics and mathematics at Columbia University. He has dedicated the majority of his career to the concept of string theory. Re-imagining the very structure of our universe, and attempting to combine understanding of the interaction of four fundamental forces of the universe, into one simple equation: a unified 'theory of everything'. Brian is coming to New Zealand in March, to give a talk, titled 'A Time Traveller's Tale'.
