  An alternative to the current accepted model of expanding universe is
presented. The proposal is anchored in the objective realist, stochastic
formulation of quantum mechanics wherein the Planck constant plays the role of
a diffusion constant which need not be an universal constant for all epochs.
This underlying noise is charecterised by a very high initial value of the
Planck constant which gradually decreased over the epochs gone by, finally
reaching its present value .It is this decrease in the strength of the Planck
constant that causes a spectral red shift with the passage of time .The
compatibility of this proposal with some cosmological data is shown.Feasible
spectroscopic measurement of a specific spectral line frequency done over a
period of a few years can decisively either validate or invalidate the proposal
in a terrestrially bound experiment. This proposal predicts a slowing down of
atomic clocks by nearly 2. 10^-18 s with respect to every preceding second. A
positive experimental outcome will validate the objective realist basis of
quantum physics as advocated by Einstein and many others.
