Subject:  Science Targets and Forecasts for PICO - Probe of Inflation and Cosmic Origins

The Probe of Inflation and Cosmic Origins (PICO) is a next generation space based mm/sub-mm imagining polarimeter with unprecedented sensitivity. With 21 frequency bands from 21-800 GHz, 1 arcmin resolution at 800 GHz, and combined map noise equivalent to 3250 Planck missions, PICO promises new discoveries across a wide range of science targets in physics, astrophysics, and cosmology. I will give an overview of the various science goals and predictions. These include detecting the signatures of inflation, measuring of the sum of neutrino masses, probing the reionization history of the universe, tracing the growth of structure, mapping Galactic magnetic fields, and many more! I will end with a brief explanation of how PICO achieves the sensitivity necessary for these science goals and discuss one important technology, low thermal conductance bolometers, which we have worked to develop for balloon-borne CMB telescopes.
