**3. Gravitational energy**

As we have accepted the origin of our universe was started by a big bang explosion from a gigantic mass annihilation within in a temporal (t > 0) space [4, 5], instead within an empty space as normally assumed [3]. Then before the big bang started a question may be asked, what triggers the explosion? As I will show that it must be ignited by an intense convergent gravitational force, induced by a gigantic mass M(t), that triggers the thermo-nuclei explosion which is mass to energy conversion.

Since big bang creation cannot be started from an empty space, big bang creation has to be started within a temporal (t > 0) because mass M(t) is temporal (t > 0), then a question is asked, under what physical means that will ignite the big bang explosion? I assert that it must be triggered by an extreme "convergent" gravitational force induced by mass M(t) over time as depicted in **Figure 4**.

From which we see that a huge mass M(t) had had been existed within a temporal (t > 0) space well before the big bang started. Since temporal space is a non-empty space, it allows M(t) to continuingly attracting new substances into mass M(t). Then eventually a huge induced gravitational field was created as M(t) grows. In which we see that mass M(t) is able to attract more and more substances added to her mass. Eventually M(t) behaves like a giant Black Hole or it is a black hole [8] that swallows more and more substances over time. From which we see that as M(t) is getting heavier and heavier until her "storage" gravitational pressure reaches to a point that triggers the thermo-nuclei explosion of mass M(t). From which we see that it must be the induced gravitational force that triggers the big

bang explosion instead by "time" as most cosmologists assumed [3]. Thus it is reasonable to accept that, if mass M(t) were not embedded within a temporal (t > 0) space then there would be "no" gravitational field to create by mass M(t) and there would be "no" big bang. This is one of the many examples shows that physically realizable science comes from a physically realizable paradigm. From which we had have seen virtual and fictitious conjectures based the big bang creation within an empty space and it is hard to accept those illogical predictions as from physically realizable scientist standpoint.
