Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
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.
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?
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?
When people born blind gain sight, the hardest part isn’t opening their eyes — it’s teaching the brain how to see.
No human has ever left the Solar System, and only six already-launched spacecraft will ever exit it. Will Voyager 1 remain the most distant?
Quantum entanglement links information between particles across space and time. So what happens when one of them falls into a black hole?
Forget about the terawatt lasers we're making on Earth. The Universe makes natural ones thousands of times more powerful than the Sun.
