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.

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.

Depending on how familiar you are with FQXi, you may know that we like to cause a little mischief at our conferences. Knowing that we had famed string theorist Raphael Bousso and Carlo Rovelli, one of the originators of loop quantum gravity, in the same room, we couldn't resist asking them to debate these rivals routes to a theory of quantum gravity.

Both men are passionate about their work and fierce defenders of their own theories. So, of course, we turned the debate upside down and asked them argue the *reverse* position.

So here's LQG proponent Carlo Rovelli explaining why anyone with any sense would be a string theorist, while string theorist Raphael Bousso staunchly defends LQG as the superior theory:

And if you liked that, here are some of our classic mock debates from our previous meeting.

Julian Barbour and Tim Maudlin reverse debate the reality of time:

And David Albert and David Wallace switch positions on the Many World's Interpretation of quantum mechanics:
