**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.

Table-Top Test of Quantum Gravity: Response to Sabine Hossenfelder's Critique

In response to the critique of Sabine Hossenfelder I would like to make the following comments that hopefully clarify the motivation and the analysis behindĀ our paper.

1) It is incorrect that we assume that the centre of mass degree of freedom is given as a linear (or any other) sum of momenta of individual constituents. We do not need to make any such assumption. The centre of mass degree of freedom of...
