As envisioned by Albert Einstein and his collaborators in 1935, quantum objects can be mysteriously correlated even if they are separated by large distances. But only now are researchers such as Leonard Susskind or Sean Carroll developing ideas on how this hidden quantum reality might explain not only matter but also the fabric of space and time. It is “the One,” a single quantum universe that gives rise to space, time, and matter. As Sean Carroll has pointed out, “Maybe it was a mistake to quantize gravity, and space-time was lurking in quantum mechanics all along.” For the future, “rather than quantizing gravity, maybe we should try to gravitize quantum mechanics. Or, more accurately but less evocatively, ‘find gravity inside quantum mechanics,’” Carroll suggests on his blog.
