Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
Three great things all align this August, making the Perseids a can’t-miss show. Here’s how to take advantage. When it comes to meteor showers, we have these dazzling pictures in […]
It wasn’t just the Milky Way and Andromeda two billion years ago. Here in the Local Group, our two largest galaxies dominate: Andromeda and the Milky Way. Our Local Group of […]
Did the Universe begin at time t=0? Did space and time emerge from that? The Universe, today, is expanding and cooling, as the volume of the Universe increases while the number […]
If our current laws of physics can’t predict what will happen, even probabilistically, we need something new. There are two theories we have that explain all the particles and their […]
The brightest galaxies of all neither have the most stars nor the biggest black holes. Here’s how to solve the mystery. With some 400 billion stars burning steadily, the Milky Way […]
How ‘special’ are we for life to have survived and thrived the way it did? While there are hundreds of billions of stars in our galaxy, many with Earth-sized planets at […]
What’s going on at the smallest and largest scales of all? Let’s look to the absolute limits of physics. Have you ever wondered what’s out there in the Universe, on the […]
