Changing constants, dark energy and the absorption of 21 cm radiation

Rishi Khatri and Ben Wandelt have recently proposed a new technique for testing the constancy of the fine structure constant using what may prove to be the ultimate astronomical resource of information about fundamental physics. Ben Wandelt explains the motivation for this work and the physical origin of this treasure trove of information.
