Because the rotation of the nebula creates an inward force to the center of the cloud.
i won't say it
The prevailing view is that stars form from the gravitational collapse of immense clouds of gas and dust in outer space.
We believe that stars form at the CENTERS of rotating interstellar gas clouds.
condensation level
Most clouds form when warm, moist air rises and cools, causing the water vapor in the air to condense into tiny droplets around particles like dust or salt in the atmosphere. This process creates visible clouds in the sky.
Theory that states dust and clouds condensed to form the sun and the planets by gravitational means
Dust clouds in space can gradually clump together due to gravitational attraction between particles, forming planetesimals. These planetesimals then collide and merge to form larger bodies, eventually accumulating enough mass to become planets. This process, known as accretion, is a key step in the formation of individual planets from dust clouds.
The phase change that causes clouds to form is condensation. When water vapor in the air cools and condenses on tiny particles like dust or ice crystals, it forms cloud droplets. These droplets then come together to create clouds.
The moon's gravitational pull on the earth is what causes tides.
Condensation, You cheater hahah
One process that causes clouds to form in rising air is condensation. As the air rises and cools, it reaches its dew point temperature at which water vapor in the air starts to condense into tiny water droplets. These droplets gather together to form clouds.
if they are massive enough and have sufficient gravitational force to overcome pressure forces and begin the process of nuclear fusion, which powers stars. This collapse is triggered by disturbances such as shock waves from supernovae or gravitational interactions with other clouds.
