Unraveling the Mystery of Cosmic Acceleration

During his year at Radcliffe, Paul Martini RI '21 is working on analysis tools and data from DESI to address the mystery of cosmic acceleration. The most prevalent view is that cosmic acceleration is due to some negative pressure associated with the vacuum of space, which is commonly referred to as dark energy. Other hypotheses include a modification to the theory of gravity, that is Einstein’s general theory of relativity, and an additional, scalar field that would act like an extra force of nature.
