Researchers Map the Universe with 1-Percent Accuracy
A team of researchers has measured the current size of “baryon acoustic oscillations” (BAOs) from the early universe in order to determine the distances to galaxies more than 6 billion light-years away to within 1 percent accuracy.

A team of researchers has measured the current size of “baryon acoustic oscillations” (BAOs) from the early universe in order to determine the distances to galaxies more than 6 billion light-years away to within 1 percent accuracy.
Their findings support the idea that dark energy has remained constant throughout the life of the universe.
