New Support for Alternative Quantum View

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.

Tiny Tests Seek the Universe’s Big Mysteries

The search for exotic new physical phenomena is being led by huge experiments like the Large Hadron Collider. But at the other end of the spectrum lie tabletop experiments — small-scale probes of hidden dimensions, dark matter and dark energy.

The Quantum Secret to Superconductivity

In a virtuoso experiment, physicists have revealed details of a “quantum critical point” that underlies high-temperature superconductivity.


Searching the Sky for the Wobbles of Gravity

The physicist Gabriela González is on the cusp of finding the first direct evidence of gravitational waves — soundlike wobbles in space-time produced by black holes and their kin.


Dark Energy Tested on a Tabletop

Is dark energy a cosmic chameleon that can fade into its surroundings? A recent test brings the mysterious anti-gravitational force down to earth.

Fluid Tests Hint at Concrete Quantum Reality

Surprising oil drop experiments suggest that the quantum world may not be as strange as advertised.


Search Escalates for Key to Why Matter Exists

Physicists have completed a new round of searches for the answer to why matter dominates over antimatter. But the radioactive decay that would solve the puzzle is evading them.

In Hunt for Dark Matter, Promises to Keep?

Whispers of the elusive particles are becoming stronger with a series of signals that appear to be zeroing in on a leading contender.


Perpetual Motion Test Could Amend Theory of Time

A radical theory predicting the existence of “time crystals” — perpetual motion objects that break the symmetry of time — is being put to the test.
