> what mechanism causes the primordial gas cloud to collapse? Gravitation. As I understand, all current science consider it fundamental force of nature. So, even atom have (sure, tiny) gravitational attraction, and huge gas cloud have huge total gravitational mass, and when long time unaffected by third party sources, slowly become more compact, until collapse to solid matter and eventually to BH.
