Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.

Raisin bread expanding Universe
The big question isn't whether the Universe is expanding at 67 or 73 km/s/Mpc. It's why different methods yield such different answers.
Six images of lunar craters including Centra Mare Fecunditatis, Mare Tranquillitatis, Mare Ingenii, Southweast, Schlieter Crater, Highland 1, Highland 2, and Mare Smth.
The recent discovery of a large cave on the Moon highlights the importance of caves not just for future space explorers but astrobiology as well.
A black-and-white photo of a seated person with their head in their hand, partially overlaid with an image of flames, evocatively captures the intense struggle to treat anxiety.
Manipulating a signaling pathway in mice reversed their anxiety — and offers hope for a new class of anti-anxiety medications for humans.
A vast expanse of outer space densely populated with numerous stars, including the typical star, and celestial objects of varying brightness against a dark background.
Most stars in the Universe are located in big, massive, Milky Way-like galaxies. But most galaxies aren't like ours at all.
Two astronauts in orange spacesuits and helmets prepare for a mission. A digital countdown displays "T-MINUS," with an Artemis mission patch visible on one spacesuit.
These missions will put us one step closer to the ultimate goal: crewed trips to Mars.
A worker in a hard hat and safety vest adjusts equipment in a facility alongside large red machinery labeled "Jefferson Lab." The scene fades into concentric circles, as if drawn by the powerful collider, leading to a bright light.
The largest particle accelerator and collider ever built is the Large Hadron Collider at CERN. Why not go much, much bigger?
Cover of "The Nightcrawler" featuring a chart showing China's economic growth surpassing the rest of the world, with a pixelated face overlaid. Emphasizing second-level thinking, the "Et . business" logo is in the bottom right corner.
Welcome to the Big Think debut of The Nightcrawler — a weekly newsletter from Eric Markowitz covering tech, innovation, and long-term thinking.
