Recently, a unified geometrical approach to gravitational and strong interactions was proposed, based on the methods of general relativity. According to it, hadrons can be regarded as ``black-hole type'' solutions of new field equations describing two tensorial metric fields (the ordinary gravitational, and the ``strong'' one). By extending the Bekenstein-Hawking thermodynamics to those ``strong black holes'' (SBH), we show that (i) SBH thermodynamics seems to require a new expansion of our cosmos after its ``Big Crunch''. (This thermodynamical indication being rather unique, up to now, in showing that a recontraction of our cosmos has to be followed by a new ``creation'') (ii) a collapsing star with masses approximately in the range 3-5 solar masses, once reaching the neutron-star density, could re-explode tending to form a (radiating) object with a diameter of the order of 1 light-day: thus failing to create a gravitational black hole.
