A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

Perhaps one of the most famous experiments in physics has been giving us the wrong message all these years. For nearly two centuries, the double-slit experiment has been providing a direct visual ...

Research reveals how close human vision comes to sensing the smallest possible unit of light. Here’s why that matters for ...

Over the past decades, many research teams worldwide have been trying to detect dark matter, an elusive type of matter that does not emit, reflect or absorb light, using a variety of highly sensitive ...
