Austrian Business Cycle Theory

I remember being in school and being told that physics was a closed system. So i wonder about with austrian economics, you read these amazing treatises, human action by meases and man economy in state. It might make somebody feel like whele, there's nothing further to say. Is that how you feel? Or if not, what are some avenues of research that seem fruitful to you? And again, business cycles are if you can understand what's causing them and if you can cure them. At the very least, it had a big impact on you.
