  A recent study shows, from an empirical deduction, that the number and the
presence of the blue straggler stars (BSS) in an open cluster follow a function
whose components are the ratio between age and the relaxation time, $\it f$,
and a factor, $\varpi$ , which is an indicator of stellar collisions plus
primordial binaries. The relation among the number of blue straggler stars, the
factor $\it f$, and the factor $\varpi$ of each globular cluster allows for
deriving the age of the respective globular clusters. This method has been
applied individually over 56 globular clusters containing BSS. The values
derived for the cluster ages from our methodology do not differ from those
derived from other methods. A special case is cluster NGC 104 whose age exceeds
13.8 Gyr (its age is between 19.04 and 20.30 Gyr), which would have a very
exotic explanation: the existence of an intermediate black hole in the center
of the cluster. That black hole main-sequence star (BH-MS) binaries with an
initial orbital period less than the bifurcation period can evolve into
ultra-compact X-ray binaries (UCXBs) that can be detected by LISA. On the other
hand, if that age were true, it would call into question the expansion velocity
for a flat Universe. This would call into question the case for dark energy
dominated Universe.
