Identifying the physical cause of the cosmic acceleration is a key challenge for fundamental physics in the coming decade. Answering this question requires multiple astrophysical and cosmological techniques, analysis of multiple, large-volume data sets, and synergy between theory and observations. The Dark Energy MA was created to take on this challenge. The goals of the MA are to address whether or not cosmic acceleration requires a modification of Einstein's theory of gravity, General Relativity, and if not, to probe the nature of the dark energy that is driving acceleration and that makes up 75% of the universe.
In order to meet these goals, the MA will seek to measure the dark energy equation of state parameter to high precision and accuracy and to test the consistency of General Relativity with cosmic acceleration by measuring the cosmic expansion history and growth rate of large-scale structure. The MA is engaging in the following specific activities to achieve its plans:
