Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
With people’s educations and careers on the line, can we afford to replace human judgment with blind probability?
The biggest question most often asked about dark matter is whether it exists. But astrophysically, we've long moved on to the next step.
JAXA's Martian Moons eXploration mission has just launched. The origin of Phobos and Deimos are at stake, with samples returning home soon.
The right kind of telescope can get us to our central black hole. But it took something extra to go all the way to seeing its event horizon.
While we now actively listen for aliens, we've never made an intentional long-term broadcast ourselves. What signal should we ideally send?
General relativity is incredibly difficult, both physically and mathematically. But all theorists need to learn it. Here's how to grok it.
In physics, things shouldn't need fine-tuning in order to match reality. Is naturalness a good guide toward an underlying explanation?
The Hubble "constant" isn't actually constant, evolving over both time and space. Will it ever become constant? That depends on dark energy.
Compared to the scale of the cosmos, a single human body might seem insignificant. But there's an entire Universe within each of us, too.
A huge obstacle for human bodies in space is that we fare poorly in zero/reduced gravity. Can two rotating, tethered capsules overcome that?
Despite being the innermost and most absorptive planet, Mercury "only" reaches 800 °F at its hottest. Venus is always hotter, even at night.
Back in 1988, Francis Halzen had what he called a "cute idea." His vision grew into the IceCube observatory, and earns the 2026 Nobel Prize.
Strong, durable Martian concrete needs a mix of small-grained Martian sand and pure sulfur. NASA found the ingredients are already there.
It has some researchers taking a second look at other hypotheses that have been proposed — and mostly discarded — in the past.
From base to tip, Mars's Olympus Mons is the highest known mountain in the Solar System. Evidence suggests a higher one could be out there.
From Hawking radiation, even black holes are expected to eventually decay. Do they ever reach a point where we'll see what's inside of them?
Are quantum fields real, or a mere calculational tool? 3 unique experiments show they carry energy. If energy's real, so are quantum fields.
Making more complicated, more precise predictive calculations tells us what real experiments should deliver. AI just surpassed humans at it.
The expanding Universe, CMB, and large-scale structure revealed the Big Bang. New nucleosynthesis advances deliver unprecedented precision.
