A new theory explains how fragile quantum states may be able to exist for hours or even days in our warm, wet brain. Experiments should soon test the idea.
String theory has so far failed to live up to its promise as a way to unite gravity and quantum mechanics. At the same time, it has blossomed into one of the most useful sets of tools in science.
According to our best theories of physics, the universe is a fixed block where time only appears to pass.
Richard Feynman’s famous diagrams weren’t just a way to do calculations. They represented a deep shift in thinking about how the universe is put together.
Suchitra Sebastian’s searches for quantum anomalies have led to the potential discovery of a new building block of matter.
An experiment claims to have invalidated a decades-old criticism against pilot-wave theory, an alternative formulation of quantum mechanics that eliminates the most baffling features of the subatomic universe.
How quantum entanglement connects with the “many worlds” of quantum theory.
The cognitive scientist Donald Hoffman believes that evolution and quantum mechanics conspire to make objective reality an illusion.
In a virtuoso experiment, physicists have revealed details of a “quantum critical point” that underlies high-temperature superconductivity.
