Clumps in a nebula form primarily due to gravitational instabilities within the gas and dust. As regions of the nebula become denser, their gravitational pull increases, attracting more material and leading to further clumping. Turbulence and shock waves from nearby stellar events can also compress regions of the nebula, facilitating the formation of these clumps. Eventually, these clumps can evolve into stars or planetary systems as they collapse under their own gravity.

Gravity.
Gravity is the force that causes nebulae to collapse. As particles within the nebula are pulled together by gravity, they begin to clump and form denser regions. This leads to the eventual formation of stars and planetary systems within the collapsing nebula.
Nebular fusion is the process by which gas and dust in a nebula come together to form stars. As the material in the nebula clumps together due to gravity, it becomes denser and hotter, eventually reaching temperatures and pressures where nuclear fusion reactions can occur, leading to the birth of new stars.
The main forces acting on a nebula are gravity, which causes the nebula to collapse and form stars, and radiation pressure, which can push material away from the forming stars. Additionally, magnetic fields can play a role in shaping the structure and dynamics of a nebula.
The material at the center of a nebula clumps together as material is pulled there. This allows a star to form.
As matter from a nebula condenses, it begins to form into clumps due to gravity. These clumps eventually evolve into protostars, as heat and pressure increase at their cores, initiating the process of nuclear fusion. This marks the beginning of a star's life cycle.

what do the largest clumps surrounding the protosun to begin to form
A solar nebula begins to form when a cloud of gas and dust in space collapses under its own gravity. This collapse can be triggered by a nearby supernova explosion, a shockwave from a passing star, or other disturbances in the interstellar medium.
Because the rotation of the nebula creates an inward force to the center of the cloud.
A large cloud of gas and dust from which stars are formed is called a nebula. Within a nebula, gravity causes the gas and dust to come together, forming clumps that eventually collapse to create new stars. Nebulae are often seen as glowing or dark patches in the night sky.
