The nebula began to shrink inward due to gravitational forces. As particles within the nebula were pulled toward its center, the concentration of mass increased, leading to the formation of a protostar at the core. This marks the initial stage of a star's formation.

Why would the nebula being to shrink?

A nebula may begin to shrink due to gravitational forces overcoming the internal pressure that was previously keeping it expanded. As the gas and dust within the nebula cools and condenses, gravity pulls the material together, leading to a denser region that can eventually form stars. Additionally, external influences such as shock waves from nearby supernovae can compress the nebula, accelerating the process of contraction. This shrinking can initiate the formation of new stellar objects within the nebula.


Why do nebula begin to contract?

Nebulae begin to contract primarily due to gravitational forces. As gas and dust within the nebula clump together, their gravitational attraction pulls more material inward, increasing density and temperature. This process can be triggered by external factors, such as shock waves from nearby supernovae or interactions with other cosmic structures, which compress the material and initiate star formation. As the nebula contracts, it may eventually lead to the formation of new stars and planetary systems.


1 through 7 ebula shrinks to form a spinning disk?

A spinning disk is formed by the nebula shrinking is 4. The planets forming is 7. The planets form gas and dust accumulate as a nebula matter separates into galaxies. Nebula shrink to form a spinning disk,gravity pulls gases to the center of the disk .Gas at the center of the disk becomes hot and dense enough for nuclear fusion to begin


What causes solar nebula to begin to form a solar system?

Gravity.


What comes first a Nebula or a protostar?

A nebula comes first; it is a large cloud of gas and dust in space. Under the influence of gravity, regions within the nebula can collapse to form a protostar. As the material falls inward, the protostar heats up and begins the process of nuclear fusion, eventually leading to the formation of a star.

What causes a solar nebula initially begin to form a solar system?

An explosion from outside the nebula


Where do all-stars begin their life cycle?

In the nebula!


What causes these gravitational centers to form in these huge clouds?

Because the rotation of the nebula creates an inward force to the center of the cloud.

Is a nebula held together of the outward force of gravity?

Yes, a nebula is held together by gravity. Gravity causes the gas and dust within a nebula to contract and clump together, eventually forming stars and other celestial bodies.

When do humans begin to shrink?

Humans typically begin to shrink in height around the age of 40, with the rate of shrinking increasing as they get older. This shrinking is primarily due to age-related changes in the spinal discs and vertebral bones.


Is after a supernova an adverb or adjective?

Prepositional phrases that begin with after are adverb phrases: e.g. "The nebula formed after a supernova" meaning the nebula formed afterward.
