"I think the probability game is such that that won't happen for a few thousand years," Kris Stanek, a professor at The Ohio State University who observed OK 2019 for the All-Sky Automated Survey for Supernovae, told Public Radio International. But while there's no need to panic, there's no reason to dilly-dally either. "I would think about this like insurance," he said. "I buy car insurance despite the fact that I'm a [good] driver because, you know, you never know what happens. I think humankind is spending many billions of dollars on all kinds of things that we don't necessarily need or to kill other people. I'm not a pacifist, but we should probably be spending on the order of a billion dollars a year on this kind of detection system. If we detect them, then we should also try to figure out what to do about this."
