The Atacama Cosmology Telescope
The goals of the ACT project are to study how the universe began, what it is made of, and how it evolved to its current state. This pursuit is part of the field of scientific cosmology in one which asks questions about the Universe on the largest and grandest scales. Over the past two decades, there has been a tremendous flourishing of the field, driven by many excellent astronomical measurements. This has led to the development of a precise and elegant understanding of cosmology.
