Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
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 […]
The most massive star in the known Universe is 260 times as heavy as our Sun. But viewing the early Universe will shatter that record. Place enough mass together in one […]
Our Universe may not be all there is, was, or ever will be, after all. There’s been a lot of speculative ideas put forth about the Multiverse, and I dare say […]
Before there were humans, planets, or even stars and galaxies, we had to make the first elements. Here’s how they happened. From the first moments of Big Bang to the […]
Different measurements of the Universe’s rate of expansion give inconsistent results. But this simple solution could fix everything. In 1915, Einstein’s theory of General Relativity gave us a brand new […]
Never draw a conclusion, no matter how ‘obvious,’ without doing the experiment first. We all love our most cherished ideas about how the world and the Universe works. Our conception […]
The Universe was born matter-antimatter symmetric. Here’s what happened when the last of our antimatter disappeared. Things happen fast in the earliest stages of the Universe. In the first 25 […]
In all the years of NASA, we’ve never touched the Sun before. Here’s why it’s so hard. This past weekend, NASA successfully launched the Parker Solar Probe: the first spacecraft that […]
In General Relativity, even space and time themselves aren’t what they seem. Gravity might have been the first fundamental force ever discovered, but in many ways, it remains the least-well understood. […]
The ices and rock aren’t green, and neither are the tails. So where does a comet’s green color come from? Every so often, with extreme regularity, comets will plunge from beyond […]
If the Breakthrough Starshot initiative, promoted by Stephen Hawking, works exactly as planned, it could lead to disaster. Imagine yourself on a world not so different from Earth, orbiting a […]
NASA’s Cassini spacecraft taught us more than we ever imagined about Saturn. Could we do something similar for Uranus and Neptune? From where we are in the Solar System, looking out […]
