Abstract
- The article reports on the demonstrations of the application of radio waves for chartering the large-scale structure of the universe. It examines the density patter called baryonic acoustic oscillations (BAOs) as a way of describing the universe's expansion. It also discusses that the expansion is accelerating under the influence of a dark energy.
