When what we predict and what we measure don't add up, that's a sign there's something new to learn. Could it be a new fundamental force?
Standard Model particles symmetry
The combination of charge conjugation, parity, and time-reversal symmetry is known as CPT. And it must never be broken. Ever.
Book cover of "Emergence" by David Sussillo, featuring a blue background with fish and circuit patterns, and a subtitle about boyhood, computation, and the mysteries of mind.
In this preview, the Stanford professor muses on how emergence, arriving at complex patterns from simple parts, explains AI, brains, and life itself.

Jim Al-Khalili explains how the past and future are more fluid than we may think.

In theory, the fabric of space could have been curved in any way imaginable. So why is the Universe flat when we measure it?
Binary black holes eventually inspiral and merge. That's why the OJ 287 system is destined for the most energetic event in history.
M81 Group
Over billions of years, fewer stars form, galaxies mutually recede, and the Universe becomes ever darker. Here's how fast it all happens.
wormholes
Nothing lives forever, at least, not in the known Universe. But relativity allows us to get closer than ever: from a physics perspective.
A satellite with large solar panels orbits above Earth against a colorful space background, where the cosmic clouds resemble the Hand of God carved by a dead star.
The path to exploring the high-energy Universe was clear and compelling. Here's how 2025's cuts are still causing NASA casualties in 2026.
Bald man in a dark button-up shirt gestures with his right hand while looking at the camera, against a plain white background.

Jim Al-Khalili introduces the technologies emerging from the second quantum revolution.
Millikan Lemaitre and Einstein
Not everyone accepts the scientific consensus; some even make careers out of challenging it. But only a select few do it the right way.
Side-by-side images of a nebula in space, showing colorful, wispy gas and dust shells surrounding a bright central region with numerous stars in the background.
Resembling a cosmic brain, the Exposed Cranium Nebula instead shows a dying, massive star, as JWST reveals. Its fate remains uncertain.
Digital illustration of Earth showing a large amount of space debris and satellites orbiting the planet, highlighting the issue of space junk.
What goes up into low-Earth orbit will eventually come down, bringing huge consequences with it. Be informed, not surprised!
A proactive AI-powered robotic arm holds a coffee cup while another pours milk to create latte art, all set against a grid-patterned background.
Today’s AI is built to respond. The future belongs to proactive systems.

In traveling through the expanding Universe, particles slow down while light and gravitational waves redshift. What degrades and what won't?
particle physics destroy universe
Smashing things together at unprecedented energies sounds dangerous. But it's nothing the Universe hasn't already seen, and survived.

Most failures trace back to people problems. If you want long-term success, start with your team. Here’s how to build teams that will actually last and make an impact.

Brian Cox examines why, despite billions of stars and trillions of planets, we have found no evidence of other intelligent life.
No civilization, no matter how successful, can last forever. What does the non-detection of intelligent aliens mean for our own longevity?
A view of a star-filled night sky with numerous bright stars and distant galaxies, including Hubble-dark galaxy formations, scattered across a dark background.
The discovery of CDG-2, a galaxy that's more than 99.9% dark matter, could reveal a new population of ultra-faint galaxies. But is it real?
