The disk embedding problem is of fundamental importance in the study of 4-dimensional topology. I will discuss its significance and difficulty, including how disk embedding makes dimension four intrinsically different from other dimensions. Then I will present some recent advances toward the existence and non-existence of embedded disks in 4-manifolds.
