时间机器在LHC

Time Machine at the LHC

I. Ya. Aref'eva, I. V. Volovich

摘要:

近年来,欧洲核子研究中心(CERN)大型强子对撞机(LHC)上的黑洞和膜的产生引起了广泛的讨论。我们认为有可能在LHC上检验因果关系。我们认为,如果量子引力的尺度是几个TeV的数量级,在大型强子对撞机的质子-质子碰撞可能会导致时间机器的形成(封闭的类时曲线的时空区域),违反因果关系。时间机器的一个模型是可穿越的虫洞。我们认为,在大型强子对撞机的可穿越虫洞生产截面是相同的顺序为黑洞生产的截面。可穿越的虫洞假设违反了零能量条件(NEC),并且需要类似于暗能量的奇异物质。虫洞/时间机器的衰变和LHC时间机器事件的签名进行了讨论。

英文摘要:

Recently, black hole and brane production at CERN's Large Hadron Collider (LHC) has been widely discussed. We suggest that there is a possibility to test causality at the LHC. We argue that if the scale of quantum gravity is of the order of few TeVs, proton-proton collisions at the LHC could lead to the formation of time machines (spacetime regions with closed timelike curves) which violate causality. One model for the time machine is a traversable wormhole. We argue that the traversable wormhole production cross section at the LHC is of the same order as the cross section for the black hole production. Traversable wormholes assume violation of the null energy condition (NEC) and an exotic matter similar to the dark energy is required. Decay of the wormholes/time machines and signatures of time machine events at the LHC are discussed.
