Why Time Might Not Be an Illusion
Einstein’s relativity pushes physicists towards a picture of the universe as a block, in which the past, present, and future all exist on the same footing; but maybe that shift in thinking has gone too far.

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.

All of the philosophers and physicists who have ever lived have been wrong about the real Universe because they failed to consider whether or not there could be only one verifiable universal physical condition. They compounded this lack of consideration by trying to incorporate complex, finite abstract mathematical systems into their thought processes in order to try to produce some sort of predictable reliability in the seeming chaotic diversity of reality.

Obviously, Nature must have...
