Mankind is currently “living on borrowed time” in terms of asteroid impacts, with no one knowing when the next big one will hit, Brian May has said. The Queen guitarist and astrophysicist made these remarks at the launch of Asteroid Day, which aims to raise awareness of the risks of asteroid impacts. Asteroid Day was launched with a 100x Declaration, that has been signed by the likes of Richard Dawkins, Brian Cox, Anousheh Ansari, Stewart Brand and 38 astronauts and cosmonauts. In this video Lord Martin Rees reads 100x Declaration for #AsteroidDay alongside Brian May from the London Science Museum.
