Science & Tech

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

An older man with gray hair and glasses speaks into a microphone, gesturing with one hand, against a green and grid-patterned background.
With new labs, funding models, and institutions, metascience is reinventing the machinery of discovery.
A collage featuring vintage documents, a grayscale moon map with labeled lunar missions, colored dots, and an old astronomical chart on a black background.
Government-spec’d glory projects produce tech demos. Enduring progress demands a better way forward.
A grid of twelve black-and-white icons representing various scientific fields, with “Artificial Intelligence” highlighted in red under a polygonal brain illustration.
The case that a bipartisan movement structured around progress and reform may be reaching critical mass.

Wavelengths stretch, distances grow, and temperatures cool as the Universe expands with time. How are the various cosmic parameters related?
Book cover titled "Machine Decision Is Not Final: China and the History and Future of AI," highlighting the evolution of AI China, with editor and contributor names listed in English and Chinese.
Leaders in China hope that AI and robotics can finally resolve the flaws of a centralized planned economy. But US technoculture has an edge.
A jellyfish galaxy with a bright white and yellow core is surrounded by red clouds of gas, set against a dark background filled with stars.
Weird-looking galaxies, with tentacle-like tails or prominent dual streams, appear like jellyfish or bunny ears. But that’s just the start.
A vast starry sky showcases a spinning galaxy, a relic from 12 billion years ago, among countless stars of varying brightness on a dark background.
For over 10 billion years, the cosmic star-formation rate has been dropping and dropping. Someday, the final star in the Universe will die.
Collage showing hands using a smartphone in the foreground and a vintage illustration of a printing press in the background, separated by arrows pointing opposite directions.
Digital tools are pulling us away from fixed texts and back toward fluid, interactive communication.

We first measured G, the gravitational constant, back in the 18th century. As the least well-known fundamental constant, can it be improved?
Collage with red and gray tones shows a hand writing in a notebook, crumpled paper, an iceberg, and the text “The Nightcrawler” at the top—capturing a mood of long thinking and creative struggle.
Welcome to The Nightcrawler — a weekly newsletter from Eric Markowitz covering tech, innovation, and long-term thinking.
In 2017, a kilonova sent light and gravitational waves across the Universe. Here on Earth, there was a 1.7 second signal arrival delay. Why?
A cylindrical space habitat with green landscapes and rivers, viewed from inside; two moons and a bright sun-like object are visible through large windowed sections.
NASA’s Caleb Scharf talks with Big Think about life’s long experiment in expansion.
A detailed image of the Eta Carinae star system could trick science headlines with its bright, colorful clouds of gas and dust in blue, red, and purple hues swirling around a luminous central region.
Dark matter, dark energy, and the Big Bang are all part of a solid scientific foundation. Here's why popular media often claims otherwise.
Four people work at consoles surrounded by monitors and control panels in a dimly lit NASA mission control room, with large display boards overhead.
What if the first search for life beyond Earth actually succeeded?
A bright, circular object with concentric rings and a surrounding halo set against a dark background, resembling a gap-clearing planet or other astronomical phenomena.
Planets grow from protostellar material in disks, leading to full-grown planetary systems in time. At last, the final gap has been filled.
A bald man in a blue suit and white shirt stands outdoors in Silicon Oasis, smiling, with autumn leaves and a blurred building in the background.
We chat with Mark Klarzynski, founder of PEAK:AIO, on how his company became an international player in data storage for the age of AI.
A wavy line, one meter long, transitions from dark red to bright yellow above a ruler, set against a magenta oval with a blue background featuring drawn human figures.
Until the late 20th century, there wasn't a truly universal standard. Under our current definition, everyone agrees on what "one meter" is.
Book cover of "Do Aliens Speak Physics?" by Daniel Whiteson and Andy Warner, featuring a blue background, yellow and white text, and an illustration of a robot and people interacting.
Do aliens speak the same physics that we do, with similar laws, observables, and underlying mathematics. Maybe not, argues Daniel Whiteson.
gravitational wave effects on spacetime
We've now detected hundreds of gravitational waves with LIGO, Virgo, and KAGRA. What if we tried Weber's original method in the modern day?
Silhouettes of people walk toward a large stack of books on a barren, monochrome landscape with a pale background.
The great books aren’t just classics — they’re cultural Schelling points that give our minds a place to meet up in the world of ideas.
