Open problems

Questions nobody has answered, and the labs that let you push at them. A lab pointed at a problem is a way to see WHY it is hard — never a claim of progress on it.

The three-body problem

1 lab

Cosmos Forge Established physicsSeed a cloud, choose how fast it spins, and find out what gravity makes of it.

Quantum gravity

2 labs

Causal Forge Mathematical modelBuild a causal graph and find out whether anything geometric emerges from it.
Spin Network Lab Mathematical modelLabel a graph with SU(2) spins and find out where quantum geometry allows volume.

Computational irreducibility

1 lab

Emergence Lab Computational experimentPick a rule for a cellular automaton and find out what it becomes.

The measurement problem

1 lab

Quantum Information Lab Established physicsBuild a circuit from an exact gate set and watch entanglement and spread come apart.

The string landscape

1 lab

F-Theory Lab Speculative extensionShape an elliptic fibration and read the toy gauge groups out of where it degenerates.

Do the energy conditions forbid FTL?

5 labs

Causality Arena Speculative extensionCompose a two-hop loop and hunt for closed timelike curves. This board inverts.
Energy Validator Speculative extensionRun the energy conditions on a warp metric and get a reproducible verdict.
Positive Energy Challenge Speculative extensionFind the fastest warp-like shell whose energy budget needs nothing exotic.
Soliton Drive Lab Speculative extensionShape a KdV soliton and watch six validators score what it would cost.
Wormhole Route Lab Speculative extensionShorten a route through topology rather than speed — and pay for it in exotic matter.

The Collatz conjecture

1 lab

Collatz Lab Computational experimentHalve it if even, triple it and add one if odd. Everything reaches 1, and nobody can prove it.

The halting problem

1 lab

Busy Beaver Lab Computational experimentHow long can a machine with four states run before it stops? And how would you ever know it never will?
