Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
NASA’s Chandra X-ray observatory has shown us the Universe like nothing else ever before. When it comes to the Universe, it mainly generates X-rays through high-temperature heating. X-rays from Chandra reveal […]
Instead of eternal expansion, could we just be part of a universal cosmic cycle? There are few questions that can keep us up at night the way pondering the eventual fate […]
On September 27, 1972, scientists performed the first test of Bell’s inequality. God does play dice with the Universe, after all. One of the most puzzling and counterintuitive aspects of quantum […]
Billions of years from now, dark energy will push the rest of the Universe out of reach forever. These galaxies will be the last to go. A look at the night […]
If the Sun is 93 million miles away, why does sunlight filtering through the clouds or the trees spread out? Rays of sunshine are one of those natural sights that leave […]
We can’t help but wonder if it’s habitable, or even inhabited, but the evidence isn’t there for it. Every star that fills the night sky carries along with it one of […]
If all you see is low-energy light in a myriad of directions, you can’t be sure. But this light comes from the Big Bang. There are a lot of things that […]
These three reasons are why there’s no getting around the fact that astronomy needs the James Webb Space Telescope. Even the most powerful telescope in history, the Hubble Space Telescope, […]
LIGO’s enormous arms contract and expand as gravitational waves pass through them. But, puzzlingly, so does the light within them. For the past three years, humanity has known a new kind […]
The nightmare scenario of no new particles or interactions at the LHC is coming true. And it might be our own fault. Over at the Large Hadron Collider, protons simultaneously circle […]
Shortly after the Big Bang, the Universe became completely dark. The first stars, when they ignited, changed everything. For perhaps 100 million years, the Universe was devoid of stars. The […]
An Oxford physicist tries to cast doubt on dark energy, but the data says otherwise. It was a mere 20 years ago that our picture of the Universe got a […]
Of all the experiments performed and measurements made involving fundamental particles, none has ever violated the Standard Model. Until now. If there’s one thing you can count on physicists for, it’s […]
Our biases, preferences, and ideas of simplicity and elegance can get in the way. Here’s a scientific way to cut through them all. What are the rules governing reality? If you […]
Not everyone is satisfied with the Big Bang. But every alternative is a disastrous failure. It’s treated as though it’s an unassailable scientific truth: 13.8 billion years ago, the Universe […]
Some wildfires will always be unavoidable. But nature, thankfully, recovers relatively quickly. The past few years have brought some devastating wildfires to large parts of the American west. A wildfire […]
Dark matter is our leading theory for a reason. New, detailed studies of the smallest galaxies could kill off the most studied alternative. When you look out at the Universe, […]
One of the most popular viral videos about space is dead wrong. But it gives us a chance to learn something incredible. There are a lot of moving parts to […]
It took hundreds of thousands of years to make atoms for the first time. If things were just a little different, it could have taken an eternity. When it comes […]
Stars don’t stay the same throughout their life, and the Sun is no exception. Here’s what’s going on. Here on Earth, the ingredients for life to survive, thrive, evolve, and sustain […]
