LIGO listens for merging black holes — but what if it could detect alien megastructures too? Gravitational wave technosignatures open a strange new channel in the search for extraterrestrial intelligence.

What if we could detect alien life without knowing its chemistry? Assembly theory's molecular complexity index might do exactly that — measuring the construction history of molecules as a universal signature of biology.

The Lurker Hypothesis is the most unsettling response to Fermi's paradox: advanced civilizations don't broadcast — they place monitors. Patient, passive, waiting. The hypothesis is scientifically testable, which makes it worth taking seriously.

JWST wasn't built to find aliens, but its infrared sensitivity to atmospheric chemistry makes it the first instrument capable of detecting biosignatures on exoplanets at scale. Here's what it can realistically see — and where the limits are.

The classic SETI assumption is that alien civilizations want to talk. Freeman Dyson proposed a different target: look for what they build. A civilization harvesting its star's entire energy output would leave an infrared signature detectable across the galaxy.

Scientists searching for extraterrestrial intelligence have moved beyond radio signals. Technosignature science now looks for any non-natural anomaly in astronomical data—waste heat, megastructures, atmospheric chemistry.

Topology studies properties that survive deformation — the deep structure beneath surface geometry. Applied to coherence, it reveals something surprising: the shape of integrated mental states has measurable, distinctive features that standard neuroscience can't see.
