Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
Solid, liquid, and gas are the three everyone learns. Plasma is the fourth. But there are two more, and they’re fascinating. How many states of matter are there? When you […]
We’re looking back farther in time than ever before. Here’s what we’re finding. Even today, the Universe is forming enormous numbers of new stars: from various nebulae throughout our galaxy to […]
It happened 13.8 billion years ago, so why hasn’t the radiation all passed over us by now? For the past 13.8 billion years, our Universe has been expanding, cooling, and gravitating. […]
They said the “missing half” of the Universe’s matter was just found. But what they found barely makes a dent to the big picture. When we look up into the great […]
The origin of the 3rd element on the periodic table was one of the great cosmic mysteries. We just solved it. How did we form the elements that pervade the Universe […]
It’s not only about what’s happening right now. Things need to change for good. It could be your colleague, your coworker, your staff member, or your student. As the world mourns […]
Maybe 100% of stars don’t have planets, after all. When stars form in the Universe, they’re created in giant bursts. A stellar nursery in the Large Magellanic Cloud, a satellite galaxy […]
It’s not just about SpaceX and Starlink. What we’re deciding today will have a global impact for years and decades to come. For countless millennia, human beings have gazed up into […]
To find the optimal route between many different locations, we need the power of quantum computers.
The double-slit experiment, all these years later, still holds the key mystery at the heart of quantum physics. When we divide up matter into the smallest possible chunks that it’s made […]
In order, they go: hydrogen, helium, oxygen, carbon, neon, nitrogen, magnesium, silicon, iron, sulfur. Here’s how we made them. Everything found on planet Earth is composed of the same ingredients: atoms. […]
Extraterrestrial life should arise fairly easily. But intelligence is another matter entirely. Planet Earth has been around for the past 4.5 billion years or so: about the last third of […]
If you traveled in a straight line for far enough, would you come back to where you started? If you were to set out on a journey from anywhere on Earth’s […]
Find a clear western horizon after sunset, and this ‘triple treat’ of a dance can be yours. Every once in a while, the night sky provides a spectacular feast for our […]
There are three things your new theory must do in order to be taken seriously as science. This one’s 0-for-3. Every once in a while, a revolutionary idea comes along that […]
We just found the first one within 1,000 light-years of us. But there’s probably one much, much closer. For a long time, black holes were known to exist only in the […]
Is that required for detectors like LIGO and Virgo to work? Whenever any two things in the Universe interact at the same location in spacetime, one thing always remains true about […]
If we’re going to open major workplaces, we have to be ready for this enormous information gap. When it comes to knowing your medical status, the ideal scenario is to […]
There’s a million things we haven’t done. But just you wait. The Universe as we know it began some 13.8 billion years ago with the onset of the hot Big Bang. […]
On the largest scales, dark matter holds the Universe together. But on small ones, it helps reveal exactly what it is… and isn’t! Dark matter is often thought of as the […]
