Chapter 372 - 371 Red Giant Star
The journey to the Cosmic Center is a long and lonely process.
Constant Star Lu Chen led the entire Wandering Star System flying through the dim Universe, constantly releasing Gravity and absorbing interstellar material nearby.
Regrettably, due to the intensifying crisis of the Universe’s halted expansion, civilizations escalated the plundering of materials, causing various interstellar materials scattered throughout the Universe to drastically decline. Taking the period after the Wandering Alliance defeated the Electromagnetic Civilization and set sail again as an example, during that lengthy journey, the Wandering Alliance hardly absorbed any interstellar material. They only encountered some microscopic particles, which was essentially equivalent to nothing.
Thus, they continued their solitary flight for a while, until suddenly, a light appeared ahead.
The presence of light meant there was matter, especially since light signifies the presence of a Constant Star, prompting scientists from the Wandering Alliance to immediately carry out astronomical observations.
At first, they thought the source of the light should be a Celestial Civilization, but observation revealed that it was not a Celestial Civilization, but merely an ordinary Constant Star.
However, strictly speaking, that Constant Star was not ordinary, because according to scientists’ observations, that Constant Star was experiencing rapid expansion. Judging by the red light it emitted, this indicated that the Constant Star had passed through the prime stage of a Main-sequence Star and entered the old age, which is the Red Giant Star phase.
The Red Giant Star is an inevitable stage in the long life of a Constant Star, just as humans will inevitably enter old age.
The principle behind the formation of a Red Giant Star is quite simple. It mainly occurs because the Hydrogen Element in the core area is exhausted, and the Helium Element, which is produced over a lengthy period through Hydrogen Nuclear Fusion, cannot yet undergo nuclear fusion due to the lack of necessary conditions. Therefore, the nuclear fusion reaction originally occurring in the core starts to spread to the outer layers of the core. By then, the core begins to compress inward because it has accumulated a large quantity of Helium Element under the effect of gravity collapse. However, the energy released by the Hydrogen Nuclear Fusion occurring in the outer layer pushes outward, resulting in a unique phenomenon in the Constant Star: the inner core compresses inward, while the outer structure expands outward, forming an opposite phenomenon of contraction and expansion.
This is why the Red Giant Star stage can expand to such a terrifying extent.
