任何量子引力理论面临的一个重大挑战是，如何在量化广义相对论的同时，保留它的部分几何特征。我们提出了新的证据，证明这可以通过直接量子化空间本身来实现。我们计算了一个四面体的Bohr-Sommerfeld体谱，结果表明它再现了在环状引力中发现的空间颗粒的量子化。
A major challenge for any theory of quantum gravity is to quantize general relativity while retaining some part of its geometrical character. We present new evidence for the idea that this can be achieved by directly quantizing space itself. We compute the Bohr-Sommerfeld volume spectrum of a tetrahedron and show that it reproduces the quantization of a grain of space found in loop gravity.
