Is Planck’s Constant - A Cosmological Variable?

Within the expanding cosmic Hubble volume, Hubble length can be considered as the gravitational or electromagnetic interaction range. Product of ‘Hubble volume’ and ‘cosmic critical density’ can be called as the ‘Hubble mass’. Based on this cosmic mass unit, authors noticed five peculiar semi empirical relations in atomic, nuclear and cosmic physics. With these applications it is possible to say that – during the cosmic evolution, magnitude of Planck’s constant increases with increasing cosmic time. This may be the root cause of observed cosmic red shifts. By observing the cosmological rate of change in Planck’s constant, the future cosmic acceleration can be verified from the ground based laboratory experiments. With reference to the current concepts of distant and spatial variation of the fine structure ratio, variation of the planck’s constant can be considered for further analysis.
