工程量子泡沫
Engineering the Quantum Foam
摘要：
1990年，阿尔库别雷在广义相对论的时空模型中提出了一种比光速更快的"曲速驱动"的设想，即物体在一个本身在空间中移动的空间气泡中实际上是静止的，从而达到这样的速度，其想法是气泡的速度本身不受光速的限制。然而，这种情况需要外来物质来稳定气泡的边界。在这里，这个建议是重新审查的背景下，新的空间模型，其中空间是一个量子系统，即量子泡沫，与正在进行的经典化。这一模型解决了一些长期存在的问题，包括对所谓的"暗物质"效应的动力学解释。它还首次给出了量子引力效应的证据，因为实验数据表明，表征空间自相互作用的一个新的无量纲常数是精细结构常数。这里的研究开始的任务是检查在没有奇异物质的情况下，新的空间自相互作用动力学在稳定边界方面可以发挥多大作用，以及边界稳定动力学是否可以被工程化;这将相当于量子引力工程。
英文摘要：
In 1990 Alcubierre, within the General Relativity model for space-time, proposed a scenario for `warp drive' faster than light travel, in which objects would achieve such speeds by actually being stationary within a bubble of space which itself was moving through space, the idea being that the speed of the bubble was not itself limited by the speed of light. However that scenario required exotic matter to stabilise the boundary of the bubble. Here that proposal is re-examined within the context of the new modelling of space in which space is a quantum system, viz a quantum foam, with on-going classicalisation. This model has lead to the resolution of a number of longstanding problems, including a dynamical explanation for the so-called `dark matter' effect. It has also given the first evidence of quantum gravity effects, as experimental data has shown that a new dimensionless constant characterising the self-interaction of space is the fine structure constant. The studies here begin the task of examining to what extent the new spatial self-interaction dynamics can play a role in stabilising the boundary without exotic matter, and whether the boundary stabilisation dynamics can be engineered; this would amount to quantum gravity engineering.
