1) How are the birth and death of stars?

In the present work, I shall explain the gravity and life cycle of a high mass Stars. Mathematical equations are important factors to describe the role of a gravity as a dark fabric distortion. The space of Universe is not empty at whole, but it is completed by a dark fabric matter and energy that distorted under the stress of a high mass Stars from their Birth to a Death. Dark fabric is warping strongly under the effect of Neutron Stars and black holes. Blue Supergiant stars are high mass Stars where their masses are very high may burn their fuel very quickly to produce new heavy atoms, and release tremendous amount of energy, and plasma. All main sequence stars in such high mass may die and expand to become a red supergiant when their fuel of fusion exhausted at the final stages of a star’s lifetime. Supergiant stars may die and explode with a big and luminous explosion that named a supernova. The remnant core of high mass stars may become a neutron star or black hole according to the mass of an exploded stars.

According to the newly established B. Feng's physics theory, the birth of stars is due to the long-term gravitational attraction in the cosmic space with abundant dust conditions, which gathers these dust particles and becomes larger mass celestial bodies. Due to gravitational compression, the core region of a massive celestial body compresses its atoms under sufficient pressure, causing electrons and protons to recombine into neutrons that enter the nucleus, forming isotopic atoms with lower atomic numbers. This process releases enormous nuclear energy, making it a glowing star that requires continuous consumption of smaller particles such as dust or cosmic objects as so-called "fuel" to maintain its luminous properties; When the surrounding material's fuel are consumed and become scarce or depleted, the star will gradually dim until it becomes a dark star, and then slowly grow into a larger mass supernova. Before encountering a collision explosion, it will further grow into a black hole, losing its basic characteristics as a star, which is the extinction of the star.
