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

Line graph titled Inflation Compounded Over 40 Years, showing eight exponential growth curves from 1% to 8% that illustrate the compound interest behind the current affordability crisis.
Einstein never said his famous "compound interest" quote. But the math of compound interest — and its inverse, inflation — explains so much.
Book cover for “Circuit Breakers: How Neuroscientists Get Inside Your Head” by Anna Chambers, PhD, featuring a colorful watercolor illustration mapping the brain.
In an excerpt from her new book, Circuit Breakers, Anna Chambers explains how brain-mapping research leads to more questions than answers.
A large, bright blue star next to a smaller, orange star against a starry space background, both marked with rotational axes to highlight the roundest object in the universe.
Nearly everything has angular momentum, so even massive, self-gravitating objects don't become perfect spheres. Which one comes the closest?
Diagram showing the elliptical orbit of the Rubin Observatory dwarf planet candidate 2026 ED138 in relation to the orbits of Jupiter, Saturn, Uranus, and Neptune.
Some are clamoring to make it the Solar System's 6th official dwarf planet. They'll be shocked to learn how rich our own backyard truly is.
An adult and baby giraffe gracefully stand in a lush, grassy field with trees in the backdrop, showcasing nature's wonder that no government can censor.
Every leading scientific idea today will eventually be proven wrong: superseded by a more correct one in the future. Getting there is hard.
dark matter
Back in 1933, Fritz Zwicky postulated the existence of dark matter. Only 40 years later, with Vera Rubin's work, did we take it seriously.

What's communicable or reachable is different from what's observable and unobservable, and all of that will evolve as the Universe expands.
standard model structure
The idea of grand unification is a tempting one for our Universe, and a fascinating suggestion. But nature won't necessarily cooperate.

1g is our acceleration in Earth's gravity: 9.8m/s². If a spaceship constantly accelerated at that rate, here's how far we could travel.
Deep space image showing a cluster of stars and galaxies with a white rectangular outline highlighting a small dark area.
In this all-new Starts With A Bang podcast episode, find out how stellar streams have the power to reveal the nature of dark matter.
m87 jets black hole spitzer
Back in 2004, a supermassive black hole from 10.8 billion years ago was found, weighing in at 66 billion solar masses. How is this possible?
invisibility cloak
Two types of nanotechnology, metalenses and metamaterials, could soon make Star Trek's long-imagined "cloaking device" a reality.
A schematic drawing of a human head filled with geometric spheres, symbolizing AI philosophies, with small figures working on a scaffolding structure around it.
AI will likely impact everything from the economy to the battlefield, but exactly how remains to be seen.
Portrait of a smiling man in a rust-colored button-down shirt that looks like a pangram of warm autumnal tones.
Max Spero discusses how AI detection has changed, the future of online trust, and why we’re in “a time of norm-building.”
A headshot of a woman with curly, dark hair featuring a gray streak, looking directly at the camera against a dark background.
“How could AI fit into a world in which everyone has the ability to have a joyful life? That is the fundamental question that I am interested in answering.”
The printed Declaration of Independence, beginning with the title “In Congress, July 4, 1776.”
With people’s educations and careers on the line, can we afford to replace human judgment with blind probability?
A human profile silhouette composed of a collage of technological, historical, and scientific objects against a starry night sky.
The debate gets clearer when you split it into three questions.
An visualization of dark matter across the universe
The biggest question most often asked about dark matter is whether it exists. But astrophysically, we've long moved on to the next step.
A Martian Moons eXploration probe with gold-colored insulation and solar panels flies in front of Mars, with the cratered moon Phobos visible in the distance.
JAXA's Martian Moons eXploration mission has just launched. The origin of Phobos and Deimos are at stake, with samples returning home soon.
Four side-by-side panels showing the same area of space with increasing magnification, moving from a wide view of the Milky Way to a detailed infrared image from the Hubble Space Telescope.
The right kind of telescope can get us to our central black hole. But it took something extra to go all the way to seeing its event horizon.
