Nine decades in, the foundations of quantum mechanics remain mysterious. Meanwhile, modern physicists puzzle over how to reconcile quantum mechanics with gravity. I will suggest that these problems are related, and that a promising strategy suggests itself: rather than “quantizing gravity,” we should look for gravity within quantum mechanics. This approach has interesting consequences for how we think about the nature of space and time.
