修正狭义相对论的动机
Motivations to modify special relativity
摘要：
在狭义相对论的框架内，所有粒子都是点状或弦状的。粒子的这种性质导致了量子场论、弦理论和超弦理论的发散困难。在狭义相对论的框架下，由于通常的惯性坐标系中m空间和相空间的非均匀性，玻尔兹曼关于等体积元概率相等的假设不再适用。这使得构造洛伦兹不变的多粒子系统的统计力学和热力学变得非常困难。此外，还报道了对狭义相对论本身及其实验事实的一些观察。通过这些观察得出的结论是：狭义相对论不是一个终极理论;需要作一些修正;任何修正都不能违背光速恒定性和定域洛伦兹不变性;看来我们必须改变狭义相对论中关于无引力时空定域结构的假设。
英文摘要：
In the framework of special relativity, all particles are point-like or string-like. This nature of particles has caused the divergence difficulties in quantum field, string and superstring theories. In the framework of special relativity, due to the non-uniformity of the m-space and phase space in the usual inertial coordinate system, Boltzmann's hypothesis of the equality of the probability of equal volume element is no longer appropriate. That makes it very difficult to construct Lorentz-invariant statistical mechanics and thermodynamics for many-particle systems. Besides, some observations on special relativity itself and its experimental facts are also reported. The conclusions from these observations are: Special relativity is not an ultimate theory; Some modification is needed; Any modification must not violate the constancy of the light speed and the local Lorentz invariance; It seems that we have to change the assumption on local structures of gravity-free space and time in special relativity.
