Probing the Opposite Ends of Time with the Cosmic Microwave Background Radiation

The next generation of Cosmic Microwave Background (CMB) experiments will open a new window on the universe. By making precision measurements of the CMB polarization on large angular scales, we may see signature of inflation carried by gravity waves. Through measurements of temperature anisotropy on small angular scales, we can discover distant galaxy clusters, constraining dark energy by providing a measure the universe's expansion history. These advances are made possible by new technology. I'll discuss the next generation of CMB experiments that employ recent advances in detector, readout, and cryogenic technology. These experiments are reaching the field now.
