Dr. Richard Fork says that the proposed system is scalable enough deal with wayward comets
Last year, the University of Strathclyde in Glasgow put forward the idea of using fleets of laser-toting satellites to deflect potentially dangerous objects away from Earth. Now, Dr. Richard Fork, principal investigator for the Laser Science and Engineering Laboratory at the University of Alabama and his team have refined the idea, saying that it’s not only feasible, but could handle anything up to the size of a comet.
