论文摘要
我们研究了宇宙尺度上的速度（超亮型）和tardyonic（跨膜，普通）巨大波数据包的时间传播。可正常的波数据包在动量空间中不能是单色的，因此获得了随行距离增加的位置不确定性（或数据包宽度）。我们研究了该位置不确定性如何影响地球宇宙辐射的检测时间的不确定性的问题。 In the ultrarelativistic limit, we find a unified result, $δx(t)/c^3 = m^2 δp t /p_0^3$, where $δx(t)$ is the positional uncertainty, $m$ is the mass parameter, $δp$ is the initial momentum spread of the wave function, and $p_0$ is the central momentum of the wave packet, which, in the ultrarelativistic limit, is equal to它的能量。该结果对Tachyons和Tardyons有效。正在讨论它的解释。
We investigate the time propagation of tachyonic (superluminal) and tardyonic (subluminal, ordinary) massive wave packets on cosmic scales. A normalizable wave packet cannot be monochromatic in momentum space and thus acquires a positional uncertainty (or packet width) that increases with travel distance. We investigate the question of how this positional uncertainty affects the uncertainty in the detection time for cosmic radiation on Earth. In the ultrarelativistic limit, we find a unified result, $δx(t)/c^3 = m^2 δp t /p_0^3$, where $δx(t)$ is the positional uncertainty, $m$ is the mass parameter, $δp$ is the initial momentum spread of the wave function, and $p_0$ is the central momentum of the wave packet, which, in the ultrarelativistic limit, is equal to its energy. This result is valid for tachyons and tardyons; its interpretation is being discussed.
