More than 14,000 known asteroids zip through Earth’s neighborhood. They will all miss Earth in the coming decades. But hundreds of thousands more have not yet been discovered, and whether any of those are on course to slam into our planet, no one knows. So finding and tracking all the asteroids that could cross Earth’s path would allow officials to issue warnings and potentially provide time to deflect dangerous ones. The community of scientists contemplating such doomsday possibilities is small and usually cordial — at least until Nathan P. Myhrvold barged in.
Nathan Myhrvold says that scientists using a prominent NASA space telescope have made fundamental mistakes in their assessment of the size of more than 157,000 asteroids they have observed.
Millionaire techie Nathan Myhrvold is used to stirring up controversy over issues ranging from patent licensing to dinosaur growth rates, but now he’s weighing in on an even bigger debate: the search for potentially hazardous asteroids.
Nathan Myhrvold tells CNN's Fareed Zakaria about how an asteroid could have changed the 20th century.
