One of my undergrad Chemistry profs was part of the team that tried to replicate Pons & Fleischmann’s results back in 1989, and, ultimately, debunked them, when they were forced to conclude that the original study had ultimately been faulty data.
Dr. Thomas said that it broke his heart. Most of the scientists on the team had been quite hopeful, going in.
P&F have been replicated several thousand times by this date. Remember Dolly the cloned sheep? Replicated ONE time only.
