"Physics Principle Reversed: Like-Charged Particles Attract, Opposites Repel"

A study from Oxford University has challenged a fundamental principle of physics by demonstrating that similarly charged particles in solution can attract each other, with the effect varying based on the solvent. This overturns the long-held belief that like charges repel. The research has implications for various scientific processes, including self-assembly and crystallization, and suggests a need to re-evaluate our understanding of electromagnetic forces. The study also provides evidence for the ability to probe properties of interfacial electrical potential due to the solvent, which were previously thought immeasurable.

"Surprising Discovery: Like-Charged Particles Attract, Challenging Basic Physics Principle"

A new study from Oxford University challenges the fundamental principle that like-charged particles repel each other, demonstrating that similarly charged particles in solution can attract each other over long distances. The study found that negatively charged particles attract each other in water to form clusters, while positively charged particles repel. The effect was found to be pH-dependent and could be switched by changing the solvent. These findings have implications for various processes involving interparticle and intermolecular interactions and provide evidence for probing properties of interfacial electrical potential due to the solvent.
