In the present study, a time-varying Hubble coefficient in the Euclidean framework is introduced assuming that the Hubble law observed in the LTD framework is still applicable in the Euclidean framework.
On this assumption, the flight time of photons between emission and reception is [t.sub.S] = [D.sub.C]/c, which is proportional to the [D.sub.C] that goes into the linear Hubble law.
