Topological string theory is a description devoid of metric and hence is background independent and everything emerges from pure topological considerations. This should put it at the front of all other candidate string theories, but that is not the case (it is certainly considered important, but not the most important).(adsbygoogle = window.adsbygoogle || []).push({});

Why is that so?

Is one reason that of a general feeling that there is only so much that can emerge from pure topology and so its good for studying just toy models?
