We spoke to Hassan recently at @perimeterinstitute.ca, where he's working with @nafshordi.bsky.social to detect quantum echoes in #GravitationalWaves as a way to prove #QuantumGravity.

A few years ago, FQxI funded Adam Brown for Complexity, Black Holes, and Observers. The aim was to show that maybe the real barrier in the black-hole information puzzle is computational, not a breakdown of physics.

Dark matter ≠ dark energy. Dark matter is an unseen mass we infer from gravity; dark energy labels an expansion that seems to speed up. In this clip from FQxI's latest podcast, Niayesh Afshordi talks about why the evidence behind each is different and why the story’s still being told.
