What is a force that causes a nebula to contract?
A key force that causes a nebula to contract is gravity. The mass of the gas and dust within the nebula generates gravitational attraction, pulling particles closer together. As these particles coalesce, their density increases, leading to further gravitational collapse. Additionally, other factors such as shock waves from nearby supernovae can trigger the contraction process by compressing the nebula.
Does a nebula turn into a white dwarf?
A nebula does not directly turn into a white dwarf. A nebula will collapse to form stars. Low to medium mass stars become white dwarfs after they die. Some are the result of a supernova and do not collapse, they merely dissipate over time. The Crab Nebula is the most prominent example of this.
What are some events that can disturb the Equilibrium of a nebula and cause it to begin to collapse?

What are the small dense remains of a high mass star?
The small dense remains of a high mass star are either a neutron star or a black hole, depending on the mass of the original star. Neutron stars are formed from the core collapse of a massive star and are incredibly dense, composed mainly of neutrons. Black holes are formed when the core collapse results in a singularity with infinite density and a gravitational pull so strong that not even light can escape.
How stars form within a nebula?
Interstellar gas is inelastic. To compress it some event typically must occur. A supernova, for example, produces a shockwave that collapses interstellar gas, precipitating nearby star formation. Another force is gravity--we have seen stars form in the swirling wake of passing black holes. When two nebula collide, we might infer star formation across the "impact zone," much as water droplets precipitate when a moist warm air mass collides with a cooler, denser mass of air.

In the formation of our solar system nearly all the mass of the solar nebula became?
In the formation of our solar system, nearly all the mass of the solar nebula became the Sun, which accounts for about 99.86% of the solar system's total mass. The remaining material formed the planets, moons, asteroids, and comets. This process involved the gravitational collapse of the nebula, leading to the Sun's formation at the center, while the residual matter coalesced into the various celestial bodies orbiting it.

What name is given to the concentration of mass that formed at the center of the solar nebula and eventually became the Sun?
The name given to the concentration of mass at the center of the solar nebula that eventually formed the Sun is the protosun or solar protostar. This dense core accumulated gas and dust, triggering nuclear fusion to ignite as a star.
What affects a nebular to collapse more?
A nebula collapses more readily when it is subjected to external pressures, such as shock waves from nearby supernovae or interactions with other celestial bodies. Additionally, the nebula's mass and density play crucial roles; regions with higher density are more likely to overcome internal thermal pressure and gravitational forces. The presence of cooling mechanisms, like radiation, also facilitates collapse by reducing thermal support against gravity. Ultimately, the balance of these factors determines the likelihood and efficiency of a nebula's collapse into stars or other celestial structures.
Where does a cycle of a star begin?
Stars usually begin their lives in stellar nurseries: (relatively) dense clouds of interstellar gases. Critical densities may be achieved when nearby stars go nova, at which time pockets in the nebula collapse under their own weight to form a protostar. If the mass of the protostar is sufficient, further gravitational collapse will cause the temperature and pressure in the core to rise to the point where hydrogen starts to fuse. At that point, a star is born.
