Forming of our Galaxies or Atmosphere

[Ewrim]

Hello dear people, I'm Evrim, 18 years old, from the Netherlands. Dear people, I am this time things investigating about science. I'm almost done with my questions, Really it will be good and u make me than happy if u can help me.


- Dear people was during or after the formation of ranges of the galaxy's, high, flat and wide? It was true that our universe had a ranges or slits, before/during the formation of our galaxy’s? And had the gravitational force a major role during the formation or beginning of our galaxy’s?


- was our atmosphere or galaxy's formed with ‘smoke’ (i.e. an opaque highly dense and hot gaseous composition) and after forming of the smoke, did the gravitational force or fusion they kept or link each other (such as the smoke with the galaxy’s), to form our galaxies?

- and after the atmosphere or galaxy’s has been formed, was it combined or there was a some combination with centrifugal force with formation of the stars? If its true, there was a combination or combined with centrifugal force with the formation of the stars? So, how important was that? Was the centrifugal force important for forming of our galaxy’s or stars?

I hope you'll forgive me, i am sorry if i did bother you

With kind regards,

Evrim

I'm having trouble understanding your questions but I'll try to answer the best I can.

- Dear people was during or after the formation of ranges of the galaxy's, high, flat and wide? It was true that our universe had a ranges or slits, before/during the formation of our galaxy’s? And had the gravitational force a major role during the formation or beginning of our galaxy’s?

I don't know what ranged and slits mean. The early universe consisted of low density hydrogen and helium gas. Quantum fluctuations enabled different areas to have slightly different densities. Where the density was higher, gravity pulled the gas together to make the first stars and galaxies.

- was our atmosphere or galaxy's formed with ‘smoke’ (i.e. an opaque highly dense and hot gaseous composition) and after forming of the smoke, did the gravitational force or fusion they kept or link each other (such as the smoke with the galaxy’s), to form our galaxies?

No, most of the mass of normal matter in a galaxy is in the form of hydrogen and helium gas clouds. These are mostly transparent, but can absorb and emit specific wavelengths of light. Some galaxies have prominent dust lanes that are easily visible, but this is only a small portion of the total matter in a galaxy.

- and after the atmosphere or galaxy’s has been formed, was it combined or there was a some combination with centrifugal force with formation of the stars? If its true, there was a combination or combined with centrifugal force with the formation of the stars? So, how important was that?

During the collapse of gas clouds, angular momentum is conserved, which allows a very small rotation to turn into a very quick one. This is why galaxies, stars, and planets generally spin around their axis.
