Finite size of the $S^3$ universe suggests that the maximum spatial uncertainty should be $({\Delta} x)_{Max}=2{\pi} R_{Univ}$, where $R_{Univ}$ is the radius of the universe. It follows from the Position-Momentum uncertainty principle ${\Delta}x{\Delta}p \geq h/2{\pi}$, that there exists a minimum uncertainty in the momentum - i.e., $({\Delta}p)_{Min}=h/(2{\pi})^2 R_{Univ}$. Similarly, the finite duration $T$ of the $S^1$ Time Cycle, suggests that the maximum temporal uncertainty is $({\Delta}t)_{Max}=T$. It follows from the Time-Energy uncertainty principle ${\Delta}E{\Delta}t \geq h/2{\pi}$, that there exists a minimum uncertainty in the energy - i.e., $({\Delta}E)_{Min}=h/2{\pi}T$. These consideration suggest the following conclusions - (1) Quantum states with ${\Delta}E \leq ({\Delta}E)_{Min}$ and ${\Delta}p \leq ({\Delta}p)_{Min}$ will be indistinguishable, (2) It should be possible to determine radius of the finite $S^3$ universe, i.e., $R_{Univ}=h/[(2{\pi})2({\Delta}p)_{Min}]$, by locally measuring $({\Delta}p)_{Min}$ , and (3) Determine duration of the universe's time cycle, $T=h/2{\pi}({\Delta}E)_{Min}$ , by locally measuring $({\Delta}E)_{Min} . . If one considers the 5000 years Time Cycle T, and 5000 light years radius of the S3 universe - as propunded by Brahma Kumaris; one obtains the prediction $(\Delta p)Min= 2.230893507958458×〖10〗^(-53) kg m/s$; and $(\Delta E)Min= 6.688050482871086×〖10〗^(-45)$ Joules.
