Does feedback matter in star cluster formation?

Feedback from stars is usually thought of as a crucially-important ingredient in models of star cluster formation and early evolution, being credited with disrupting clusters, terminating (and triggering) star formation, setting the IMF, making the cluster optically visible, etc. However, recent simulation results have cast doubt on feedback’s ability to do all of these things. I will discuss these issues and try to indicate what feedback can do, what it can’t do, and why it’s still important at star cluster scales and beyond.
