The observed structure in the universe is a treasure-trove of information but accessing it is complicated by non-linear evolution, bias, and systematics. I will discuss novel approaches to access the abundant fluctuations modes beyond the linear regime to probe the questions of cosmic acceleration, dark matter, and the cosmic beginning.
What can we learn from cosmic structure?
