Episode 752: Q&A 151: Would They Warn Us About the End of the World? And More...

In this week's questions show, I explain what would happen if scientists discovered an existential threat to humanity. Would they let us know, or keep it secret to avoid a panic? Could we detect a Breakthrough Starshot fleet coming our way? And how well does China communicate its space exploration to the public?
