大自然不会在普朗克尺度下掷骰子
Nature does not play dice at the Planck scale
摘要：
我们从经典的广义相对论出发，将其与物质场耦合起来。每个组态变量和它的共轭动量，也作为时空点，被提升到矩阵的状态[等价算子]。这些矩阵服从普朗克尺度下的确定性拉格朗日动力学。通过在比普朗克时间大得多的时间间隔上粗粒化这个矩阵动力学，我们得到了作为低能涌现近似的量子理论。如果足够多的自由度发生纠缠，就会发生自发局域化，从而导致经典时空几何和经典宇宙的出现。在我们的理论中，暗能量被证明是一种大尺度的量子引力现象。量子不确定性不是基本的，而是由于我们没有在普朗克尺度上探索物理学。
英文摘要：
We start from classical general relativity coupled to matter fields. Each configuration variable and its conjugate momentum, as also space-time points, are raised to the status of matrices [equivalently operators]. These matrices obey a deterministic Lagrangian dynamics at the Planck scale. By coarse-graining this matrix dynamics over time intervals much larger than Planck time, one derives quantum theory as a low energy emergent approximation. If a sufficiently large number of degrees of freedom get entangled, spontaneous localisation takes place, leading to the emergence of classical space-time geometry and a classical universe. In our theory, dark energy is shown to be a large-scale quantum gravitational phenomenon. Quantum indeterminism is not fundamental, but results from our not probing physics at the Planck scale.
