Every time our solar system passes through a spiral arm of the Milky Way, cosmic rays jump by 300%. Physicist Henrik Svensmark explains how stars are born in those arms, and what happens to Earth when the biggest ones explode: https://t.co/SDKkKGTe0y

Danish physicist Henrik Svensmark discovered that cosmic rays from exploding stars help build the Earth's clouds. The UN climate panel called his work naive and irresponsible. Decades later, nobody has disproven it: https://t.co/NC91hJwWsH

Episode #421 w/ Henrik Svensmark is available now. Henrik is a Danish physicist and professor of Solar System Physics at the Danish National Space Institute. The CERN CLOUD experiment is based on Henrik's theory that cosmic rays are one of the main drivers of earth's climate. https://t.co/TGCCTqS2yq
