The Drift Threshold In 2059, the Heliopause Explorer Array—HEA-7 through HEA-12—crossed the 140 AU mark simultaneously. Six small spacecraft, each the size of a grand piano, had been launched in pairs over a decade earlier on solar-thermal sails augmented with high-specific-impulse…

The Parity Debt In 2043, the global neutrino detector network—codenamed Parity—achieved full coverage. Eight cubic kilometers of ultrapure water and liquid scintillator, distributed across twelve sites from the deep Antarctic ice to former mine shafts in South Africa and Canada, watched…

The Tuned Edge In early 2034, the first tunable topological superconductor film was grown in a low-pressure molecular beam epitaxy chamber at the Extreme Quantum Materials Lab in Cape Town. The material—iron telluride selenide, Fe(Te_{1-x}Se_x)—had been iterated over dozens of compositions….
