The quantum gravity vacuum must contain virtual fluctuations of black hole microstates. These extended-sized fluctuations get “crushed” when a closed trapped surface forms, and turn into on-shell “fuzzball” states that resolve the information puzzle. We argue that these same fluctuations can get “stretched” by the anti-trapped surfaces in an expanding cosmology, and that this stretching generates vacuum energy. The stretching happens when the Hubble deceleration reduces quickly, which happens whenever the pressure drops quickly. We thus get an inflation-scale vacuum energy when the heavy GUTS particles become nonrelativistic, and again a small vacuum energy when the radiation phase turns to dust. The expansion law in the radiation phase does not allow stretching, in agreement with the observed irrelevance of vacuum energy in that phase.

弹性真空

量子引力真空必须包含黑洞微态的虚拟涨落。当一个封闭的被困表面形成时，这些扩展大小的波动被“粉碎”，并变成解决信息难题的壳上“模糊球”状态。我们认为，在膨胀的宇宙学中，这些相同的波动可以被反俘获表面“拉伸”，并且这种拉伸会产生真空能量。拉伸发生在哈勃减速迅速减少时，每当压力迅速下降时就会发生这种情况。因此，当重 GUTS 粒子变得非相对论时，我们获得了暴胀尺度的真空能量，当辐射阶段变成尘埃时，我们再次获得了小的真空能量。辐射阶段的膨胀定律不允许拉伸，这与在该阶段观察到的真空能量无关。
