20 Unsolved Scientific Problems As Compiled by Grok (3/4).

"Identifying 20 experiments with anomalous laboratory results that remain unexplained by current physics is challenging because many anomalies are either resolved over time or lack sufficient evidence to be considered robust. Anomalous results in physics often arise from experimental errors, statistical fluctuations, or misinterpretations, and many initially puzzling findings have been explained or retracted."
