The Cosmic Microwave Background Radiation Is the Oldest Light in the Universe

i play a small role on these two large teams, if you don't mind. Broadly speaking, both o our collaborations build telescopes to measure the cosmic micre wave background radiation is the oldest light in the universe. And so i would actually say that we're afield that's progressing and how much we can get out of the measurements. The c m b has kind of been a field that's ben around for it was first discovered in the sixties.
