Theoretical Quantum Mass

In the present theoretical work, attempts have been made to find the least mass, which quantifies the discrete mass, in terms of the reduced Planck constant and cosmological constant in the Heisenberg position-momentum uncertainty relation as well as by employing the time period of oscillating universes in mass-time inequality. It has been estimated and reported that the least mass exists in the range 5.98 × 10-74 < m < 2 × 10-68 kg, which quantifies discrete masses in the universe of size < 8.64 G ly.
