我们的宇宙的长距离有效场论-标准模型耦合到重力-有一个独特的四维真空，但我们表明，它也有一个景观的低维真空，与潜在的模量所产生的真空和卡西米尔能量。对于最小的马约拉纳中微子质量，我们发现了一个近似连续的无限大的AdS 3 × S1真空，周长约为20微米，AdS 3长度为4 × 1025米。通过AdS/CFT，在这个真空中存在中心电荷c ~ 1090的CFT 2，它包含与量子引力耦合的标准模型（以及更高）。对于能量在10 - 1 eV到1048 GeV之间的真空，这些真空中的物理与我们的真空相同，因此这个CFT 2也描述了我们真空在这个能量范围内的所有物理。我们表明，它是可能实现量子稳定的AdS真空作为近视界区域的新类型的量子极端黑物体在高维空间-近临界黑弦在4D，近临界黑洞在3D。卡西米尔能量对零能条件的违反对于这些视界的存在至关重要，正如Emparan，Fabbri和Kaloper已经意识到的那样。新的极端3D黑洞特别有趣-它们是（Meta）稳定的，熵独立于和GN，因此在GN → 0极限下熵的微观计数是可能的。我们的结果表明，它应该是可能的实现更大的景观AdS真空弦理论作为近地平线几何的新的极端黑膜解决方案。
The long-distance effective field theory of our Universe—the Standard Model coupled to gravity—has a unique 4D vacuum, but we show that it also has a landscape of lower-dimensional vacua, with the potential for moduli arising from vacuum and Casimir energies. For minimal Majorana neutrino masses, we find a near-continuous infinity of AdS3 × S1 vacua, with circumference ~ 20 microns and AdS3 length 4 × 1025 m. By AdS/CFT, there is a CFT2 of central charge c ~ 1090 which contains the Standard Model (and beyond) coupled to quantum gravity in this vacuum. Physics in these vacua is the same as in ours for energies between 10−1 eV and 1048 GeV, so this CFT2 also describes all the physics of our vacuum in this energy range. We show that it is possible to realize quantum-stabilized AdS vacua as near-horizon regions of new kinds of quantum extremal black objects in the higher-dimensional space—near critical black strings in 4D, near-critical black holes in 3D. The violation of the null-energy condition by the Casimir energy is crucial for these horizons to exist, as has already been realized for analogous non-extremal 3D black holes by Emparan, Fabbri and Kaloper. The new extremal 3D black holes are particularly interesting—they are (meta)stable with an entropy independent of and GN, so a microscopic counting of the entropy may be possible in the GN → 0 limit. Our results suggest that it should be possible to realize the larger landscape of AdS vacua in string theory as near-horizon geometries of new extremal black brane solutions.
