Magnus Magnusson interviewed Carl Sagan and Stephen Hawking in 1988.

Do you think God can intervene in the universe as he wants? Or is God, too, bound by the laws of science?

Your question of whether God is bound by the laws of science is a bit like the question 'can God make a stone so that is so heavy he cannot lift it?' I dont think it is very useful to speculate on what God might or might not be able to do, rather we should examine what he actually does with the universe we live in. All our observation suggests that it operates according to well defined laws. These laws may have been ordained by God, but it seems that he does not intervene in the universe to break the laws.
