Science & Tech

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

A technician in a cleanroom suit works by a large cylindrical piece of equipment in a high-tech laboratory setting with industrial tools and machinery.
A recent experiment challenges the leading dark matter theory and hints at new directions for uncovering one of the Universe's biggest mysteries.
Satellite image showing a dense cloud mass over the southeastern United States and the Gulf of Mexico, with an inset graph from NOAA depicting hurricane frequency peaking around mid-August to late September, a trend exacerbated by global warming.
The laws of physics aren't changing. But the Earth's conditions are different than what they used to be, and so are hurricanes as a result.

Most fundamental constants could be a little larger or smaller, and our Universe would still be similar. But not the mass of the electron.
Image of Mimas, one of Saturn's moons, partially illuminated. The large Herschel crater is prominently visible on the right side of the moon's surface.
The existence of another watery world in the outer solar system may offer clues to how such seas form — and hope for another spot to search for life.
A collage features a tennis player and a basketball player against a backdrop of financial charts, graphs, and mathematical equations on a checkered pattern.
How Daniel Kahneman and Amos Tversky cracked open behavioral economics and enlightened all our choices.
Two breathtaking pictures of a galaxy and a star taken by the Hubble telescope, highlighting the beauty and cosmic magnitude that fuels the Hubble tension.
In the expanding Universe, different ways of measuring its rate give incompatible answers. Nobel Laureate Adam Riess explains what it means.
A black-and-white portrait of a man with curly hair, glasses, and a beard is centered against a green and blue background with abstract DNA helix patterns, representing leadership essentials.
Benjamin Oakes — CEO of buzz-worthy biotech company Scribe Therapeutics — joins Big Think for a chat about innovation, human endeavor, and more.
The image shows a bright spot labeled "JADES-GS-z13-1-LA," seemingly an impossible light captured by the JWST, surrounded by measurement markers, including a scale bar for 1 kpc and 0.28 arcsec. Filters and colors are listed at the bottom.
The Lyman-α emission line has never been seen earlier than 550 million years after the Big Bang. So why does JADES-GS-z13-1-LA have one?
A detailed image of two galaxies in space, one with spiral arms on the left and the other, more elliptical, on the right, surrounded by distant stars.
Galactic activity doesn't just arrive when supermassive black holes feast on matter. Before, during, and after all create fascinating signs.

Although a great many unidentified sights have been seen in the skies, none have conclusively demonstrated the presence of aliens. So far.
A detailed image of the moon with visible craters and surface textures, set against a dark sky filled with numerous stars.
Finding life beyond our Solar System requires understanding its host planet.
A graph depicting projectile motion with displacement on the vertical axis and time on the horizontal axis. The projectile's trajectory forms a perfect parabola, with initial velocity u and angle θ clearly indicated.
Taught in every introductory physics class for centuries, the parabola is only an imperfect approximation for the true path of a projectile.
A world map displays global climate zones with colors representing varying levels of temperature and precipitation: green for temperate, yellow for arid, orange and red for hotter regions, and blue for wet zones.
The salinity of the oceans is not just a matter of taste. Saltier water behaves differently, too.
A person is giving a presentation at a podium with a large abstract, colorful light pattern displayed on a screen behind them.
Inflation, dark matter, and string theory are all proposed extensions to the prior consensus picture. But what does the evidence say?
A satellite orbits Earth against a backdrop of space. Below, the Earth's curvature and cloud formations are visible, making our planet seem even bigger.
The observation that everything we know is made out of matter and not antimatter is one of nature's greatest puzzles. Will we ever solve it?
A historical timeline featuring notable figures from 1400 to present, including scientists, writers, politicians, and artists. The timeline is categorized by different historical eras.
"The Big Map of Who Lived When" plots the lifespans of historical figures — from Eminem all the way back to Genghis Khan.
A person lies in bed reading a book, wearing a white blouse, in a painting with soft, muted colors.
With the right prompts, large language models can produce quality writing — and make us question the limits of human creativity.
Portrait of an older man with a beard wearing a hat, depicted in purple tones, with scientific and alchemical symbols in the background, capturing the essence of a truth machine.
Why human attempts to mechanize logic keep breaking down.
A storefront with signs for psychic telepathy readings and a phone number. Two white plastic chairs are placed in front. The storefront is pink with a black awning and a large hand sign advertising $10 readings.
Thinking of a number between one and ten? Here's how predictable human responses create the illusion of telepathy.
