Science & Tech

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

A weathered metal sign reading "PROGRESS" with an arrow stands in a barren desert landscape under a blue sky.

“People got skeptical, fearful, doubtful of the very idea of progress in the 20th century and we allowed that to slow down progress itself.”
gravity probe b
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.
A petri dish with a red agar medium shows various colonies of bacteria growing, with dense streaks on the right and scattered colonies on the left.

“Chance invents and natural selection propagates that chance invention.”
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?
A timeline diagram showing portraits of various scientists, documents, and equations connected by arrows, illustrating the historical development of quantum mechanics.

“The messy reality of it is that all of these very smart people, including Isaac Newton, were talking to other people.”
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.
terraforming
The first world beyond Earth for human habitability should be the Moon, not Mars. This is why we should terraform our lunar neighbor first.
Book cover for "The History of Money: A Story of Humanity" by David McWilliams, featuring stacked coins arranged in a Fibonacci sequence on a black background with white and gold text.
Fibonacci’s "Liber Abaci" not only revolutionized commerce — it also helped nudge the world towards reasoned, quantitative enquiry.
two particles different wavelength speed of light
Times dilate and lengths contract near the speed of light. Bizarre and confusing? Sure. But under relativity, it can't be any other way.
Book cover of "The Shortest History of AI" by Toby Walsh, featuring blue and white text on a dark background with a small glowing circle near the center—an apt nod to early AI like Logic Theorist.
In this excerpt from "The Shortest History of AI," Toby Walsh explores the history of the Logic Theorist, the first AI to prove mathematical theorems.

“Over the last 10 or 15 years, scientists have really started to understand the fundamental underlying biology of the aging process. And they broke this down into 12 hallmarks of aging.”
