Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
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 […]
All the things that surround us and make us up weren’t always here. But where did it all come from? The Universe, as we see it today, sure is full of […]
We all share atoms with every person, living or dead, on Earth. There’s more in common among us than you might think. When you eat food, drink liquids, or even breathe […]
A generation ago, NASA launched their great observatories to explore the Universe. It’s time for round 2. Throughout the history of astronomy, every advance we’ve ever made has come about because […]
It’s 100 years since astronomy’s famous ‘great debate.’ We still haven’t learned the most compelling lesson of all. So, you’ve arrived at a crossroads: you think the world works in a […]
In both visible light and infrared, we get a preview of the spectacular advances that await the James Webb Space Telescope. What astronomers see isn’t just determined by the telescope […]
Visiting even one friend can undo all the good work that social distancing has accomplished. Over the past few months, people all over the world have come to realize just […]
Over the past 30 years, we’ve revolutionized what we know about the Universe. But we couldn’t have done it without these lessons. On April 24, 1990, the Hubble Space Telescope rocketed […]
Its record-holding galaxy is 32 billion light-years away, in a Universe that’s only 13.8 billion years old. On April 24, 2020, humanity celebrates the 30th anniversary of NASA’s Hubble Space Telescope. […]
