**The Quantum Reality Paradox**

How the search for God’s limits led to the discovery of quantum contextuality—a weird phenomenon that could provide the 'magic' needed for super-fast computing.

**Quantum Cybernetics**

The quest for a meta-theory of quantum control that could one day explain physical systems, certain biological phenomena—and maybe even politics.

**Video Article: Solar-System-Sized Experiment to Put Time to the Test**

Is quantum theory or relativity right about the nature of time? Bouncing radar beams off the moons of Jupiter just might help sort things out.

**Conjuring a Neutron Star from a Nanowire**

Using tiny mechanical devices to create accelerations equivalent to 100 million times the Earth’s gravitational field—mimicking the arena of quantum gravity in the lab.

**Inferring the Limits on Reality (that Even the Gods Must Obey)**

The fuzziness of the quantum realm could arise from mathematical restrictions on what can ever be known.

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 behind 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...
