Tiny quantum fluctuations in the early universe explain two major mysteries about the large-scale structure of the universe, in a "cosmic tango" of the very small and the very large. A new study by researchers at Penn State used the theory of quantum loop gravity to account for these mysteries, which Einstein's theory of general relativity considers anomalous.
