First you are assuming that it is possible to travel backward in time.
Secondly, you are assuming that I have no other means of measurement. I
could, for example, look at the distance and rate of speed of well known
astronomical objects, or the spectra of well known old stars like
Cepheids (sp?), etc.
If you don't provide me with sufficient instrumentation to perform such
observations, then I can give you no meaningful answer to the question
within the bounds of science.
