Our solar system began forming within a concentration of interstellar dust and hydrogen gas called a molecular cloud. The cloud contracted under its own gravity and our proto-Sun formed in the hot dense center called solar nebula
protostar or nebula
The Sun.
This stage is called protostar formation, where the material in a nebula begins to collapse and accumulate due to gravity. As more matter collects at the center, it becomes denser and hotter, eventually triggering nuclear fusion and leading to the birth of a star.
When a nebula collapses due to gravitational forces, the center becomes denser and hotter. As the material in the center becomes more compact, the pressure and temperature increase, eventually triggering nuclear fusion reactions that sustain a star's energy. This marks the birth of a new star in the center of the collapsing nebula.
When the gas in the nebula's center stopped collapsing, it likely reached a stable equilibrium where the inward force of gravity was balanced by the outward pressure from nuclear fusion or other energy sources. This equilibrium could result in the formation of a protostar or a star, depending on the mass and composition of the gas.
It formed the sun!!

Shred Nebula happened in 2008.
Hades Nebula happened in 1987.
protostar or nebula
The material at the center of a nebula clumps together as material is pulled there. This allows a star to form.
