Abstract
Recent measurements of the cosmic microwave background radiation by the Boomerang and Maxima experiments indicate that the universe is spatially flat. Here some simple back-of-the-envelope calculations are used to explain the result. The main result is a simple formula for the angular scale of the acoustic peak in terms of the standard cosmological parameters:
