Scientific paper

The recent supernova measurements of cosmological acceleration, together with the CMB and galaxy cluster measurements, raise new important questions: Do we have a reliable, consistent picture of cosmology? What is the identity of the previously unknown energy that is causing the acceleration? To address these questions, we are designing a new supernova experiment using a satellite with a telescope (called ``SNAP,'' for SuperNova/Acceleration Probe). The goal of this project is to measure the expansion history of the universe at a 1%-2% level of precision. The various theories of the accelerating energy predict different histories of decelerations and accelerations in the universe's expansion. .
