Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
We have two descriptions of the Universe that work perfectly well: general relativity and quantum physics. Too bad they don't work together.
No matter what physical system we consider, nature always obeys the same fundamental laws. Must it be this way, and if so, why?
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?
The combination of charge conjugation, parity, and time-reversal symmetry is known as CPT. And it must never be broken. Ever.
In this preview, the Stanford professor muses on how emergence, arriving at complex patterns from simple parts, explains AI, brains, and life itself.
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.
Over billions of years, fewer stars form, galaxies mutually recede, and the Universe becomes ever darker. Here's how fast it all happens.
Nothing lives forever, at least, not in the known Universe. But relativity allows us to get closer than ever: from a physics perspective.
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.
A new framework suggests that bursts of neural chaos could be the fingerprints of a conscious mind at work.
Not everyone accepts the scientific consensus; some even make careers out of challenging it. But only a select few do it the right way.
Resembling a cosmic brain, the Exposed Cranium Nebula instead shows a dying, massive star, as JWST reveals. Its fate remains uncertain.
What goes up into low-Earth orbit will eventually come down, bringing huge consequences with it. Be informed, not surprised!
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?
Smashing things together at unprecedented energies sounds dangerous. But it's nothing the Universe hasn't already seen, and survived.
No civilization, no matter how successful, can last forever. What does the non-detection of intelligent aliens mean for our own longevity?
Throughout history, the ability to tell increasingly believable stories has become available to more people. Kevin Ashton says that’s a blessing and a curse.
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?
