THE REDSHIFT, MICROWAVE BACKGROUND, AND OTHER OBSERVABLE ASTRONOMICAL FEATURES ARE DEDUCED FROM TWO THEORETICAL ASSUMPTIONS: (1) global space-time is a certain variant of Minkowski space, locally indistinguishable in causality and covariance features but globally admitting the full conformal group as symmetries although having a spherical space component; (2) the true energy operator corresponds to a certain generator of this group which is not globally scale-covariant, whereas laboratory frequency measurements are inevitably such and correspond to the conventional energy operator [unk]/i[unk]/[unk]t.
红移、微波背景及其他可观测的天文学特征是从两个理论假设推导出来的：（1）整体时空是闵可夫斯基空间的某种变体，在因果性和协变性特征上局部不可区分，但整体上允许全共形群作为对称性，尽管具有球空间分量；（2）真实能量算符对应于该群的某个生成元，它不是整体尺度协变的，而实验室频率测量不可避免地是尺度协变的，且对应于常规能量算符[unk]/i[unk]/[unk]t 。
