摘要
Lorentz变换的根源在于,当t’=t=0时,两惯性坐标系K’和K的原点O’与O重合,这时,在其公共原点发出的是一个传播速度为光速c的光信号。经过Lorentz变换,认为光速c是一切实际物体运动速度的极限。本文假设,当t’=t=0时,两惯性坐标系K’和K的原点O’与O重合,这时,在其公共原点发出的是一个超光速信号。由此导出了Lorentz变换修正公式,并证明了超光速没有极限值,ds2仍然是Lorentz不变量。同时还导出了相对论速度变换修正公式。由此还可以导出在超光速条件下,惯性坐标系之间的其它变换公式。
The foundation of Lorentz transformation is that in condition of t' = t = 0, the origins o' and o of two inertial reference frames k' and k is coincident. At this time, the light speed signal is emitted from coincident origin. After Lorentz transformation, it is concluded that the light speed is the limit of any objective's velocities. In this paper, we assume that in condition of t' = t = 0, the origins o' and o of two inertial reference frames k' and k is coincident. At this time, a signal with a faster-than-light speed is emitted from the coincident origin. Then we derive the modified Lorentz transformation formula, and prove that there is no limit of the faster-than-light speed and ds2 is still the Lorentz invariable. At the same time, we also derive the modified speed transformation formula of the theory of relativity. By the modified Lorentz transformation formula, we can derive some other transformation formula between the inertial reference frames under the faster-than-light speed.
