A conversation with Tevian Dray, on the last day of GR21, brought to light some of the ‘elephants in the room’ with quantum gravity researchers and highlighted the essential part played by non-associative Maths – in any robust formulation attempting to address those looming concerns. While this is seen as a complication by most researchers; I assert that it is instead a clear road to a solution or family of solutions to long-standing problems in Physics. This lends support to the author’s idea that nature employs the totality of all Mathematics – discovered and undiscovered – in its handiwork, such that invariant realities in Math spell out their own importance to Physics, and give rise to the universe we see today. As those same mathematical invariants unfold in the universe over time, they also give rise to processes that make the appearance and evolution of life inevitable.
