There are a wealth of possible theoretical avenues being explored to explain the recent observations of accelerated expansion in the universe. In this colloquium I'll discuss the current status of some of these theoretical investigations into the nature of dark energy, discussing expected observational implications for matter and gravity based theories and how constraints are being placed on these with current and future data.
