Peculiar Relations in Cosmology

Within the expanding cosmic Hubble volume, the Hubble length can be considered as the gravitational or electromagnetic interaction range. The product of ‘Hubble volume’ and ‘cosmic critical density’ can be called the ‘Hubble mass’. Based on this cosmic mass unit, the authors noticed three peculiar semi empirical applications. With these applications it is possible to say that in atomic and nuclear physics, there exists a cosmological physical variable. By observing its rate of change, the future cosmic acceleration can be veri ed, time to time Hubble’s constant can be estimated and nally a uni ed model of the four cosmological interactions can be developed.
