Quantum information theory: Quantum complexity grows linearly for an exponentially long time

Physicists know about the huge chasm between quantum physics and the theory of gravity. However, in recent decades, theoretical physics has provided some plausible conjecture to bridge this gap and to describe the behavior of complex quantum many-body systems — for example, black holes and wormholes in the universe. Now, researchers have proven a mathematical conjecture about the behavior of complexity in such systems, increasing the viability of this bridge.
