Scientists are pretty sure the Universe started with the Big Bang. But the furthest back in time we can explore is 370,000 years after spacetime began. So, how do we measure the Big Bang, and how could our favorite friends - neutrinos - revolutionize our understanding of the early universe? Physicist Dr. Kirsty Duffy explores the cosmic neutrino background on #EvenBananas.
