Physical Superintelligence (PSI) claims it proved the Aaronson-Ambainis conjecture, open since 2008, using an unreleased Anthropic model. It cites Lean verification, but peer review has yet to take place.
Caltech’s ASTRA system has autonomously assembled part of a reflector antenna’s framework in low Earth orbit, the first structure built in orbit without astronauts. The feat is a milestone for DARPA’s NOM4D program and a step toward giant space solar power plants and telescopes.
Physicists rewrote Einstein’s equations and found that gravitational fields can “reconnect” and transfer energy to matter, much like magnetic reconnection behind solar flares.
