Collapsing Physics: Q&A with Catalina Oana Curceanu
Tests of a rival to quantum theory, taking place in the belly of the Gran Sasso d'Italia mountain, could reveal how the fuzzy subatomic realm of possibilities comes into sharp macroscopic focus.

Dropping Schrödinger's Cat Into a Black Hole
Combining gravity with the process that transforms the fuzzy uncertainty of the quantum realm into the definite classical world we see around us could lead to a theory of quantum gravity.

Does Quantum Weirdness Arise When Parallel Classical Worlds Repel?
Quantum mechanics could derive from subtle interactions among unseen neighboring universes

Wrinkles in Spacetime
Searching for defects in the fabric of the cosmos could help physicists home in on the correct theory of quantum gravity.

Blurring Causal Lines
Quantum experiments mix past and future on the microscopic scale—opening the door to faster computers and revising our notion of causality.
