Trivia: "Singularities" are infinitely dense points. When something is compressed to the point of having a volume of ZERO, its density is thought of as being infinite - in other words, a "singularity." A typical example is the inside (center) of a black hole. A huge star - that once had a large mass - was reduced to nothing, but that "nothing" has a density that is infinite. It is at a point of "no return" (an event horizon), so is not visible. BUT "naked singularities" could exist - and be visible.
Continuity mistake: The pile of clothes Lea took out of the dryer and placed on the table were rearranged differently when the camera shifted to the opposite side. (00:41:52)
