Fragility in finance is equivalent to mass in physics. To understand the analogy, one must go back to the origin of time itself. Crucially, the genesis of our universe is remarkably similar to the genesis of finance. This claim shall lead us to a better understanding of what antifragility means. Antifragility in finance is equivalent to antimass in physics, the hypothetical ‘dark energy’ that has eluded cosmologists for so long.
