What is Quantum Gravity at Two Loops about?
The paper demonstrates that the S matrix of pure Einstein gravity diverges at the two-loop order in four dimensions. This finding highlights the challenges of ultraviolet divergences in quantum gravity, indicating that while one-loop finiteness exists, higher-order divergences are inevitable. The analysis suggests that similar divergences may also occur in four-dimensional supergravity theories starting from three loops.
