One simple physical concept lies behind the formation

Imagine then that the gas is somehow disturbed so that
one small spherical region becomes a little denser than
the gas around it
gravitational field becomes slightly stronger.
It now attracts more matter to it and its gravity
increases further, causing it to begin to contract. As it
contracts, its density increases, which increases its
gravity even more, so that it picks up even more matter
and contracts even further. The process continue, until
