Recent astronomical observations have given cosmologists some new puzzles to ponder. Are we really seeing a breakdown of the standard cosmological model? Is the new data telling us that the dark energy is not a cosmological constant, but has a density that evolves over time? These questions, including graduate student Gabriel Lynch's efforts to understand the current cosmological situation, are discussed in a recent Scientific American article, "Latest Dark Energy Study Suggests the Universe Is Even Weirder Than We Imagined."
