Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
5 years ago, LIGO detected our first gravitational waves here on Earth. Next decade, LISA will start seeing them from space. When it comes to gravitational waves, our terrestrial laser interferometers […]
The biggest error from ‘A Brief History of Time’ continues to misinform generations of aspiring physicists. The greatest idea of Stephen Hawking’s scientific career truly revolutionized how we think about […]
We still don’t know how it came to be this way. Every once in a while, we find an object in the Universe that completely mystifies us. For generations, astronomers have […]
Here’s how the closest place to “hell” in our Solar System might actually be home to life. From afar, Venus seems like the most uninhabitable planet of all. NASA’s Magellan mission […]
The Standard Model and General Relativity can’t be all there is. But how will we discover what lies beyond them? One of the biggest problems with physics is that, apart from […]
The theoretical reasons to expect it are compelling, but the technology required to detect it is unfathomable. All throughout our galaxy, millions of black holes of a variety of masses […]
There’s a lot left to understand, ponder, and investigate. And there always will be. For hundreds of thousands of years — nearly all of human history — we had no definitive answers to some of […]
From the right place at the right time, it’s a sight unlike any you’ll find on Earth. In our Solar System, any planet with moons has a chance for a solar […]
It’s perhaps the most famous thought experiment in all of physics, but is full of popular myths and misconceptions. One of the most bizarre ideas about the quantum Universe is […]
CERN’s bold new proposal has physicists confronting the biggest question of all: is building a new collider worth it? If you want to discover anything novel about the natural, physical […]
Without a little help from Einstein, we couldn’t have made this discovery. NASA’s Hubble Space Telescope, currently celebrating its 30th anniversary, still churns out novel discoveries. The Hubble eXtreme Deep […]
This year’s June solstice coincides with a new Moon and an annular solar eclipse. Here’s how rare it truly is. As the Earth orbits the Sun, it rotates on its axis. […]
You never know what you’re going to find when you look somewhere new for the first time. Approximately 4600 feet (1400 meters) underground, beneath the Italian mountain known as Gran Sasso, […]
One look at the uncertainties and the assumptions changes the story tremendously. Is there intelligent life out there in the Milky Way beyond our own Solar System? If so, how […]
The view from beyond Pluto is far enough from Earth that we can see the stars shift. NASA’s New Horizons, humanity’s first spacecraft to encounter Pluto, is more than 4.3 billion […]
Even physicists sometimes fall for these. For centuries, the laws of physics seemed completely deterministic. If you knew where every particle was, how fast it was moving, and what the forces […]
Too little breathing room, tear gas, and insufficient masks are a recipe for disaster. Police are worsening all three. Across the nation and the world, people of all skin colors are […]
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. […]
