异地观察时空膨胀

Relativistic light aberration, relativistic Doppler effect, motion point charge electric field relativistic transformation, etc. all indicate "moving ruler elongation" rather than "moving ruler shortening".The "zero result" of the Michelson-Morey experiment, narrow relativity can no longer be explained by "moving ruler shortening", but only by "moving ruler elongation".The effects of special relativity can be expressed as a "common formula", "moving ruler shortening" is different, which is an isolated goose."Moving ruler shortening" may be a derivation error.You can export spatiotemporal expansion directly using the Lorentz transform: time expansion，space expansion，the distance or spacing expansion of the inertial system.Space-time expansion, off-site observation, "speed unchanged" can prove the initial setting of "speed of light unchanged", while "moving ruler shortening" cannot.Observing space-time expansion in different places is an observation effect, which will not have a substantial impact on space-time itself and will not change the local observation.The secret of the magical "space-time expansion" effect is to observe information - light information, which has a "space-time refraction" in the propagation between two space-time.Space-time refraction can uniformly explain the bending of various light.Conclusion: It is not "moving ruler shortening", but "moving ruler elongation" and "space-time expansion".
