What is the maximum distance that could theoreticly be measured by checking the
doppler shift of somthing? (Both the actual distance measured and the EM
frequency band that would indicate that distance when spotted)
Also, what would be the distance if the EM band had a frequency of one cycle per
universe lifetime and how does that distance compare to the furthest things we
have measured so far?
