Best Regards,
- RP | The spectroscopically determined red-shift (Doppler) method is used to determine the change in frequency of the light spectrum from a distant object.
The results from this method indicate, reasonably conclusively that the Universe is spatially expanding, the further the faster, from any observer.
Hubbles Law is another method that reaches the same conclusion.
They are not necessarily independent of each other.
