It’s not a gambit. It’s not fraud. It’s not driven by opinion, prejudice, or bias. It's not unchallengeable. And it's more than facts alone.
A shot of the Perseid meteor shower
Although the Geminids have rivaled the Perseids recently, in 2026, the Perseids should win at their peak. Here's why, plus how to see them.
Colorful nebula with red and blue gas clouds, two bright stars—once separated stars now reunited after distant supernovae—and a rocky object, set against a star-filled background in space.
We've never witnessed a system of binary stars both go supernova before. A once-hidden source of gamma rays just revealed the first one.
A middle-aged man with a receding hairline, glasses, and a blue button-up shirt looks at the camera against a plain light background.

Why does life keep getting more complex? Why doesn't evolution get stuck? Physicist Stephen Wolfram has been working on this for decades. Turns out the answer is more simple (and more strange) than we expected.
A person writes equations on a chalkboard. Their face is obscured by a digital overlay of blue 1s and 0s.
If AI can someday make scientific breakthroughs, what would be left for the brightest human minds to discover?
A molecular cloud labeled G+0.693-0.027 is shown in space, with an inset displaying a 3D model of the erythulose molecule—a sugar that may provide clues about the origin of life—found within the cloud.
In a gas cloud 26,000 light-years away, a 4-carbon sugar, erythrulose, has just been found. Here's what it means for life in the Milky Way.
Mars is very different than Earth: smaller, drier, colder, etc. But the biggest long-term challenge, for human colonies, is its low gravity.

Mathematics is our language for quantitatively describing reality, but it can also take us to worlds that never were. Physics needs more.
Two people at a protest hold signs reading "no vaccine passports" and "STOP COVID JABS FOR CHILDREN," with others standing nearby and flags visible in the background.
Astrophysicist Adam Frank used to think the consequences of rejecting science would play out on the individual level. He's since changed his mind.
Einstein
Many think that intelligence can be outsourced to AI. Einstein wouldn't have used it. If he had, he never would have become Einstein.

We experience only one small slice of the ruliad. What’s the ruliad? Stephen Wolfram explains.

Despite the brilliance of these cosmic beacons, only 1% of a core-collapse supernova's energy is observable. The other 99% is in neutrinos.
Illustration of black holes merging, showing spiraling paths and arrows indicating movement and direction, set against a dark, starry background.
With nearly 400 black hole events from gravitational waves, we can begin to infer their origins. At least two different populations emerge.
A barred spiral galaxy is shown with a bright central bar, curved arms, and scattered blue regions indicating star formation, against a dark background.
The history of atoms in the Universe is our own history: without them, there would be no us. So how do we piece their cosmic story together?
observable universe size
For all we know, the cosmos could truly be infinite in scale. But the observable part of our Universe? It's finite, and its size is known.
An aerial view of LIGO Hanford, showing two long, perpendicular arms extending across a flat, brown landscape with a few buildings at the intersection.
The LIGO facilities in the U.S. are the most sensitive gravitational wave detectors in the world. Their future remains uncertain.
cosmic inflation
We used to think the Big Bang started it all. Then we realized that something else came before it, erasing everything that existed prior.
A man with short hair and a beard speaks while gesturing with both hands; he wears a black quilted jacket against a plain light background.

"King" Willonius Hatcher, a comedian and AI storyteller, asserts that the AI revolution empowers creators to rapidly transform ideas into comprehensive projects—like pitch decks and marketing campaigns—allowing them to enhance their creative output while focusing on their core talents.
A large, circular structure—destined to become the world's best and smallest giant telescope—is under construction inside a spacious industrial facility with scaffolding and bright overhead lighting.
At "only" 25 meters in diameter, the Giant Magellan Telescope is the smallest of three current projects. That might make all the difference.
Using the newest large-scale structure data, a team of researchers announced a huge cosmic anisotropy in Nature. Too bad it's wrong.
