Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
In a 13.8 billion year old Universe, a few seconds hardly seems like it matters. But these minuscule changes sure do add up over time.
Most massive galaxies are spiral or elliptical shaped. But peculiar galaxies showcase the beautiful violence that helps explain our cosmos.
Once land plants, seagrasses staged one of evolution’s boldest reversals — returning to the ocean and reinventing their biology to thrive beneath the waves.
Early on, the Universe needed near-perfect flatness, or atoms, stars, and galaxies couldn't form. What happens once dark energy takes over?
The image you're seeing isn't a hole in the Universe, and the cosmic voids that do exist aren't hole-like at all.
While LooksMaxxing often headlines the news, the idea of BrainMaxxing deserves real attention. Growing your mind never goes out of style.

NASA astronomer Michelle Thaller makes the case that quantum entanglement may be the underlying fabric from which spacetime itself emerges.
Andy Weir’s novel blends humor, scientific rigor, and human ingenuity to make science fiction feel believable and thrilling.
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.

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.
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.
