Explore 25 science experiments that defied the laws of physics, revealing mind-bending phenomena that challenge intuition.

Out of order: quantum mechanics defies causal order. (Courtesy: Shutterstock/Sam72) An experiment has confirmed that quantum mechanics allows events to occur with no definite causal order. The work ...

Austrian physicist Erwin Schrödinger developed quantum theory’s wave equation, which describes quantum systems as waves that ...

Schematic: The experiment took place in a dye-filled cavity between two mirrors. The bottom mirror was nanostructured to create two waveguides that directed the light. In the primary waveguide, ...

Thomas Young, born 250 years ago this week, was a polymath who made seminal contributions in fields from physics to Egyptology. But perhaps his most enduring legacy is proving Isaac Newton wrong about ...

In 1971, graduate student Stuart Freedman and postdoctoral fellow John Clauser took over a room in the sub-basement of Birge Hall at the University of California, Berkeley, and built an experiment ...
