	Regarding uncaused causes:

	The recently revived "Kaluza-Klein" theories, turn non-gravita-
	tional interactions into geometrical effects by the introduction
	of additional dimensions which are assumed to have compactified
	to small ( ~ planck length ) sizes.  Popular versions involve a
	total of 11 dimensions.  If there were, say, 3 timelike and 8
	spacelike dimensions then there would be no causality at high
	energies.  Then there would be no need to find a cause for the
	big bang.
	
	Of course, there are other possible objections to the idea of
	8+3 dimensions than just causality.
