Weinberger says DARPA backed hafnium bomb idea dismissed as pseudoscience

What was said

"He said it's it's dangerous because it's destabilizing the arms race, but it's also pseudocience. It's based on some guy at Texas who did an experiment with a used dental X-ray machine. And I just I had to get to the bottom of it."

Sharon Weinberger alleges she was told DARPA funded research into a hafnium-isomer explosive concept. She says a nuclear physicist warned it could destabilise arms-race dynamics and described the underlying science as flawed.
