论文摘要
为了获得有关Alcubierre Warp Drive的来源的更多见解，该技术旨在使用公制表达式找到正交基础。推断出外来的流体可以产生与Alcubierre Warp Drive相同的应力能量张量。对于经线加速度和速度的不同配置，提供了密度，压力，总质量，总负质量，状态方程以及违反无效状态的绝对值的约束。 Alcubierre翘曲驱动爱因斯坦张量的表达和流体特性的优化导致各种物理量和经线速度之间的功率定律。调查的设置显示出小于0.004c的经线速度的状态方程式，并且似乎能够维持具有外在状态方程式的经过2200C的经线速度。
To gain more insights about what could be the source of the Alcubierre warp drive, a technique designed to find an orthogonal basis from the metric expression is used. It is deduced that exotic fluids can produce the same stress-energy tensor as the Alcubierre warp drive. For different configurations of warp acceleration and velocity, constraints on density, pressure, total positive mass, total negative mass, absolute value of the equation of state as well as null-energy condition violation are provided. The Alcubierre warp drive Einstein tensor expression and the optimization of fluid properties result in power laws between various physical quantities and warp velocity. The investigated setups exhibit non-exotic equation of states for warp velocities smaller than 0.004c and seem able to sustain warp velocities up to 2200c with exotic equations of state.
