[QUOTE="Chalnoth, post: 47687192, member: 159254"] Sorry I'm late, but here's my response to the OP. There is zero electrostatic repulsion in hydrogen gas. None. Zip. Nada. the atoms are electrically [i]neutral[/i]. It's because of diffusion that the atoms that fill a balloon will spread out to an entire room, not because they repel one another. It's only when the atoms get [i]very[/i] close together that the electromagnetic force has [i]any[/i] effect. But the collapse is nothing at all like "an exploding atomic bomb." It's a continuous process, with the photon pressure increasing only gradually as the temperature increases. The most that this photon pressure does while the star is forming is it slows down the accretion of matter. But once the inner core cools a bit more, the pressure drops back down, and more matter can fall in. It's only when the faster nuclear processes get going that the solar wind actually blows away material (as happens in red giants, for instance). As long as the gas cloud is dense enough, it's not a problem. These calculations are well-known, and show that this process is likely to be quite common in galaxies. Of course not. At most they just slightly disturb clouds, allowing some regions to be ever so slightly more dense than others so that they start collapsing. But I doubt this is a major factor in star formation. A star has a higher entropy than a diffuse gas cloud. [/QUOTE]
