In March, we released benchmark numbers alongside SpacetimeDB 2.0. After a thorough investigation, we discovered a serious error in SpacetimeDB which caused our results to be misleading. We would like to sincerely apologize to our community. Read the full article:

2/ This is the latest iteration of Shor's optimization. Different approaches choose different: - window widths, - coordinate systems, - inversion strategies, - scheduling, - QFT implementations, - measurement strategies, To try and reduce the total spacetime volume requirements (circuit width x depth) for the algorithm.

MAJOR ORDER: The Ministry of Science has identified anomalous phenomena in the vicinity of ancient Illuminate structures. These ruins date to well before the First Galactic War, and have been preserved for citizen education and enrichment. The anomalous phenomena include spacetime disruptions similar to those recorded near the Meridian Singularity. Ground-Penetrating Radar scans indicate that these ruins may extend several meters into the ground. Access to the sites is now restricted, as Ministry of Science archaeology teams begin careful excavations. However, there are similar structures on planets that the Illuminate now control. The enemy may intend to somehow use these ruins to perpetuate disinformation campaigns, or to create and propagate their own twisted version of history. Further, the seizure of these sites will allow further excavation, hastening our investigation. ALAIRT III, HERTHON SECUNDUS, and ZEA RUGOSIA, each contain multiple archaeological sites. The Helldivers are ordered to liberate these planets from the Illuminate.

Bernhard Riemann’s 1854 breakthrough proved that geometry isn't just about flat planes: it’s about the intrinsic curvature of space itself. This image perfectly breaks down the three fundamental geometries that govern our universe: > Zero Curvature (Euclidean): The classic flat plane. Parallel lines never meet, and triangle angles sum exactly to 180°. > Positive Curvature (Elliptical): Think of a sphere. Lines eventually intersect, and triangles "bulge," exceeding 180°. > Negative Curvature (Hyperbolic): A saddle-like surface where lines diverge rapidly, and triangle angles sum to less than 180°. By treating these surfaces as "manifolds," Riemann provided the mathematical framework that Albert Einstein later used to describe the warping of spacetime in General Relativity.

Adam Brown (@A_G_I_Joe) is back! General relativity is said to be the most beautiful idea the human mind has ever produced. Most of us will never get to fully appreciate its elegance by taking the 20-lecture graduate course Adam taught on it at Stanford. But in the video below, Adam distills the key idea at its heart so clearly and compellingly that even I could keep up lol. At the core of general relativity, Einstein is trying to figure out the principle behind a particular coincidence: that the mass that resists acceleration and the mass that gravity pulls on just happen to be exactly the same. Adam then leads us through the path of insight which Einstein called his “happiest thought.” Then Adam lectures on black holes. First, by showing how even under special relativity you could create a perpetual motion machine if black holes weren't truly black. And then, by explaining why the observations of an infalling observer and a distant bystander to the black hole would be so radically different Adam leads Blueshift, the team at Google DeepMind cracking science and reasoning. Which gave us the opportunity to discuss at the very end how close we are to AIs that could rediscover general relativity from scratch.
