There are some problems with this view. For instance, when gases are compressed, as under gravity, they also heat up, and this makes them expand. As temperature increases, the outward force due to expansion will become greater than the force of gravity compressing the gas and the gas will simply dissipate in space again. How then could the condensing hydrogen cloud ever ignite spontaneously?

Come on. This is a joke.

Come on. This is a joke.

Would you mind specifically explaining why? Thanks.
