Cosmic Calibration- Statistical Modeling for Dark Energy and the Cosmological Constants

It has been assumed for quite some time that the Universe is expanding (de Sitter, 1934). But in recent years, it has been hypothesized that the Universe is expanding at an accelerating rate (Perlmutter et al., 1999). A new entity called dark energy is one possible way to explain this acceleration (Riess et al., 1998). To explore this theory, observations are needed to verify th
