The Complexity Conundrum
Resolving the black hole firewall paradox—by calculating what a real astronaut would compute at the black hole's edge.

Quantum Dream Time
Defining a ‘quantum clock’ and a 'quantum ruler' could help those attempting to unify physics—and solve the mystery of vanishing time.

Our Place in the Multiverse
Calculating the odds that intelligent observers arise in parallel universes—and working out what they might see.

Sounding the Drums to Listen for Gravity’s Effect on Quantum Phenomena
A bench-top experiment could test the notion that gravity breaks delicate quantum superpositions.

Watching the Observers
Accounting for quantum fuzziness could help us measure space and time—and the cosmos—more accurately.

Quantum Reality Check
Photon experiments suggest the wavefunction is real -- and quantum cats truly are dead and alive at the same time -- as physicists Alessandro Fedrizzi and Martin Ringbauer explain. Plus, FQXi releases its first two books.

Detecting Black Hole Firewalls
If you fell into a black hole would you be stretched into spaghetti or would you catch fire? Cosmologist Niayesh Afshordi discusses the possibility that neutrinos detected on Earth hold the answer. They may have been created by a ring of fire surrounding back holes.

Our latest podcast has been posted and we’re catching up with a couple of old friends of FQXi to talk about their recent work, and making a couple of new ones.

First up we have quantum physicist Martin Ringbauer, of the University of Queensland, discussing tests investigating whether the quantum wavefunction is real. You may remember that Martin took part in one of our most popular podcast pieces last year, when he chatted to us about simulating time travel in the lab with photons. Now,...
