Yes, life exists in our Universe. No, that statement doesn’t equal science. Imagine you’ve encountered a natural phenomenon you want to understand better, but don’t have the tools to do so. […]

We’ve put so much together about the Universe. Could it all come tumbling down? We’re always on the lookout for the next big thing, and even our best guesswork is often […]
Our Sun will someday run out of fuel. Here’s what it will look like when that happens. The fate of our Sun is unambiguous, determined solely by its mass. If all […]
Every physical theory has constants in it. The gravitational constant is remarkably uncertain. When we first began formulating physical laws, we did so empirically: through experiments. Drop a ball off […]
An entire Universe of possibilities await stars like our own, even after they run out of fuel. One of the most profound rules in all the Universe is that nothing lasts […]
General Relativity had to be right. Here’s how we knew. What happens to light when it passes near a large mass? Does it simply continue in a straight line, undeflected from […]
Despite being free to users, Facebook seems to have a monopoly on our speech, our data, and our lives.
Depending on how you measure it, there are two different answers that could be right. If you want to see what’s out there in the Universe, you first have to be […]
Wide Angle Motion Imagery (WAMI) is a surveillance game-changer. And it’s here.
Evolution doesn’t clean up after itself very well.
The first image of an Event Horizon is here. Here’s what it means. Variety isn’t just the spice of life, but a natural consequence of living in our Universe. Gravitation, obeying […]
If dark matter doesn’t interact with normal matter or light, how can it be heated up? One of the great cosmic mysteries of our time is the presence and existence of […]
It’s not what you have, it’s what you do with it.
No matter how long you wait, the matter that makes you probably won’t end up inside a black hole. It’s one of the most pervasive ideas out there: if you wait […]
The study shows when the ‘Napoleon complex’ is most likely to emerge.
A single thought experiment reveals a paradox. Could quantum gravity be the solution? Sometimes, if you want to understand how nature truly works, you need to break things down to […]
It was so well-motivated and compelling. But the particles never appeared. Every so often, an idea comes along in theoretical physics that’s undeniably profound. When a single idea can solve […]
The world’s greatest clockmaker sent a clock to the new world, and everything went haywire. The reason why will shock you. For millennia, humanity’s one-and-only reliable way to keep time was […]
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, […]
Easter eggs have been hidden in video games since Atari’s Adventure; now Google search has hidden an entire adventure game.
From the inflationary state that preceded the Big Bang to our cold, lonely, dark energy-dominated fate, the Universe goes through six different eras. We’re living in the last one already. The […]
The expanding Universe really is accelerating, and no dusty scenario can explain it. 20 years ago, our understanding of the Universe underwent a revolution. For generations, we had known the Universe […]
These three reasons are why there’s no getting around the fact that astronomy needs the James Webb Space Telescope. Even the most powerful telescope in history, the Hubble Space Telescope, […]
Technology holds the promise of a better future, but our footprint on the planet threatens to undo all our dreams and progress. It’s pretty easy to look at the world […]
The story of that one time a U.S. city was run by a Soviet, and what it was like to live in it.
What should a black hole look like? Our theoretical predictions are about to meet our first observations. In science, there’s no moment more exciting than when you get to confront […]
You’d be amazed at what you can learn from even one single pixel. Over the past decade, owing largely to NASA’s Kepler mission, our knowledge of planets around star systems beyond […]
What happened 4.56 billion years ago is the most important part of the cosmic story ever to happen to us. If you were to look at our Universe at the time […]
Theoretical work tells you where to look, but only experiments can reveal what you’ll find. There are fundamental mysteries out there about the nature of the Universe itself, and it’s our […]
In his final years, Martin Luther King, Jr. become increasingly focused on the problem of poverty in America.
