论文摘要
有人认为，像颗粒的量子状态一样，在任何大小的光锥上都应相干。一个精确的经典解决方案，即相对论点粒子的重力冲击波，用于估计一致的能量流中的重力阻力，以及虚拟横向真空能量波动对因果钻石表面的预期重力效应。有人提出，标准模型真空状态的适当时空平均的重力效应导致观察到的宇宙常数的小非零值，以强相互作用量表的虚拟gluonic弦的重力拖动主导。
It is argued that quantum states of geometry, like those of particles, should be coherent on light cones of any size. An exact classical solution, the gravitational shock wave of a relativistic point particle, is used to estimate gravitational drag from coherent energy flows, and the expected gravitational effect of virtual transverse vacuum energy fluctuations on surfaces of causal diamonds. It is proposed that the appropriately spacetime-averaged gravitational effect of the Standard Model vacuum state leads to the observed small nonzero value of the cosmological constant, dominated by gravitational drag of virtual gluonic strings at the strong interaction scale.
