My feelings are that I'd be cautious about directly linking the origins of the universe with the origin of the 10000 things. Taoism teaches us that there are no absolutes and already scientific theory is moving beyond the big bang with ideas such as M-theory and ideas that "time" in some form can pre-exist the big bang. There will also be the limitless manifestations of Tao which are forever beyond our knowing. What is interesting is that again and again in science we come across the same ideas as are found in Taoism and it is no surprise that we see something of the origin of the 10000 things reflected in our knowledge of the big bang.
As for Taoism and science? I'd venture that most scientists don't know or understand Taoism. Certainly those that encountered it like Bohr clearly saw the conceptual links between Physics and Taoism. Taoism is a series of statements of demonstrable fact combined with conclusions on what this tells us about how we can live our lives. The statements hold true wherever they are applied and so are just as valid in Physics or Mathematics. For example, by my understanding, Mandlebrot's analysis of the length of the coast of Britain demonstrating that a finite area can be enclosed by a line of infinite length is easily predicted from the opening lines of the Tao Te Ching - for exactly the same reasons. Equally Mandlebrot's work is an elegant example of the meaning of "The Tao that can be named is not the eternal Tao".
The advancement of science has been repeatedly held back by adopted orthodoxies - like the belief of God's hand at the heart of everything, celestial bodies moving in perfect circles, or the mechanistic predictable view of the universe's workings. These orthodoxies have repeatedly led to the dissenters being ostracised, outcast or whatever until, in a revolution brought about by a failing of the old orthodoxy, suddenly the old paradigm is overturned leading to some of the dissenters being validated. To the best of my knowledge, each time this has happened the new paradigm has moved closer to a picture of the universe in accord with that of Taoism.
Taoism doesn't need science to validate it, and science doesn't need Taoism - but the roots of both are the same and I believe each can provide something useful to the other.
