The stability and longevity of elements in our fuel supplies is of paramount importance for the sustainability of our civilisation. The nuclear fusion fuels used in our Sun are of especial importance as almost all of our renewable energy resources derive directly from this source. In this case longevity runs into billions of years. A proposed explanation of this longevity, which applies specifically to the stability of stellar hydrogen fuel, is presented and examined. The explanation is consistent with well-established features of our general understanding of matter and quantum physics. It also has many other relevant features relating to important factors concerning life on our planet. These include: the suspected quantum-based origin of the phenomenon of forward moving time and the 2 nd Law of Thermodynamics; the, as yet, largely un-researched importance of the interaction dynamics of the up and down quarks and their attendant gluons; the suspected importance of these interactions in the fusion control dynamics of stars; and the suggestion that gravity is initiated in a similar way by these dynamic interactions which exist but are below observation level at the quantum scale. Also considered are the nature and consequences of the only Universe known to us which seems to combine both symmetrical and asymmetrical features working together harmoniously. It is also concluded that quantum-sized mechanisms are of exceptional reliability in controlling matter. Finally, it is suggested that the present world energy supply situation is reaching a more critical phase requiring a stop-gap approach to allow important superior technologies to catch up with perceived needs.
