Nonsense! "Gravity" cannot even attract a single oxygen molecule in the Earth´s atmosphere! Use your comparative and logical senses.
Good grief.
You are confusing cloud of mostly hydrogen in space -
HI regions (molecular hydrogen, H2, where hydrogen are atoms are electrically neutral, hence it is called “molecular cloud”)
& HII regions (hydrogen in plasma state)
- with planetary atmosphere.
You wanted me to respond to “cosmic cloud of gas and dust“, so my my replies (post 106) and then post #114 in response to you about “strong nuclear force”, and that was me making the efforts to talk to you about “cosmic cloud of gas and dust“ and Stellar Nucleosynthesis.
My previous posts were to explain to you that not all cosmic clouds are plasma. Some are, and some are not. The second reply (#114) was to explain what need to occur first before Nucleosynthesis start.
Now. You are changing the subject on me, by trying to shifting the goalpost, from “cosmic cloud of gas and dust” to “Earth’s atmosphere”.
I brought up the two types of cosmic clouds that exist in space, and I brought up what occur before Nucleosynthesis start, and what happens when Nucleosynthesis start. Then I attempt to explain to you about how stars can form from these clouds, HENCE, the area of cloud need to contract and reach certain density and temperature, before Nucleosynthesis start.
Why are you changing subject on me?
The cosmic clouds and planetary atmosphere are two different subjects. So I am refusing to change from subject to subject on your whim.
Do you understand what I am saying about gravity playing role of coalescing the hydrogen (whether it be neutral gas or hydrogen plasma), into body of mass, before star form.
This body of mass must reach density due to contraction by gravity, in order to reach the temperature necessary for nuclear fusion start (hence Nucleosynthesis), about 15 MK for proton-proton reaction type Nucleosynthesis and 17 MK for CNO-type Nucleosynthesis.
Only when nuclear fusion starts, is here that strong nuclear force played role.
You are forgetting that the strong nuclear force maybe the strongest force, but strong force are limited to quantum range (eg formation of baryon particles consisting of quarks) and atomic range (eg what keep protons together in atom’s nucleus).
The denser the matter, like stars and planets, the more it will attract smaller matters and hydrogen atoms like in the cosmic clouds. Strong nuclear force won’t attract matters or particles that are beyond the range of the nucleus.
Do you understand that?
