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. %K Hubble length %K cosmic critical density %K Hubble mass %U http://www.ptep-online.com/index_files/2013/PP-33-04.PDF
