A shark fin is heading straight for you. Steadily, terrifyingly, the  shark is closing in. Even if you don’t have galeophobia, which is a fear  of sharks, you’re certainly scared now. Should you stay still? Should  you splash around and throw underwater punches?  How do you keep from  being bitten?  Underknown shows take you to the frontiers of science, tell the greatest  underknown stories from history and make the most complex ideas and  theories entertaining and accessible. Underknown takes you beyond the  familiar to explore, question and marvel at the magnificent vagaries of  life on Earth and the Universe and ponder our best hopes for our planet,  our lives, our children and our future.
