Based on measurements of B-mode polarization in cosmic microwave background radiation, last March, BICEP2 reported the detection of gravitational waves caused by inflation in the early universe. The POLARBEAR experiment is studying this B-mode polarization to answer other questions: What is the overall structure of matter in the universe? What are the masses of neutrinos? And what is the nature of dark matter and dark energy? New data proves the feasibility of this approach. Full Story
