The two planets most suited for habitability had very different fates. At last, scientists know why. Imagine the early days of our Solar System, going back billions of years. The Sun […]

The highest-energy particles on Earth reach enormous energies, but it’s nothing compared to what the Universe can achieve. Deep underground in Europe, the world’s most powerful particle accelerator lives in a […]
Technology’s rapid advances may slow down, limiting our possibilities.
How do you know you are real? A classic paper by philosopher Nick Bostrom argues you are likely a simulation.
Study shows minerals sequester carbon for thousands of years, which may explain oxygen’s abundance in the atmosphere.
The darkness of the night sky was a mystery for generations of humans. Here’s the reason why. From our perspective here in the Solar System, it makes absolute intuitive sense why […]
And how cutting just $1 billion per year in funding from NASA’s budget would be a catastrophe for science. When you think of the great cosmic beyond and what we know […]
When the Universe gives us clues, we ignore them at our own peril. When you approach the world scientifically, you seek to gain knowledge about how it works by asking it […]
Particle physics is everywhere, even in the palm of your hand. When you hold out your palm and point it towards the sky, what is it that’s interacting with your hand? […]
We all have obstacles to overcome in pursuit of our goals. For Santa Claus, it’s clear that science is the key. Of all the challenges we face in our work, perhaps […]
It’s very different from the colloquial meanings of “true-and-false” or “right-and-wrong.” In many ways, the human endeavor of science is the ultimate pursuit of truth. By asking the natural world […]
If dark energy is causing the Universe to disappear, how can we still find and see ultra-distant stars and galaxies? In the 1920s, scientists discovered that the Universe was expandingbased […]
Two of our biggest science-fiction dreams might not remain fiction for much longer. Here’s how 21st-century science could make it real. For as long as human beings have looked up at […]
Zizek is on the left and dislikes political correctness. How does that work out?
Scientists discovered microbes that have lived on Earth for millions of years.
The ability to instantaneously jump from one location in space to another clearly violates the laws of physics. Or does it? There are a few rules in the Universe that seem […]
The farther away they get, the smaller distant galaxies look. But only up to a point, and then they get magnified. Here’s how. Intuitively, we all know that when we see […]
Wide Angle Motion Imagery (WAMI) is a surveillance game-changer. And it’s here.
One often-neglected result of climate change is ocean acidification. If this process continues, we may start to see fewer fish and more jellyfish.
30 years later, a new investigative documentary on Bob Lazar’s claims about Area 51 raises some ghosts, some hell, and some unsettling questions.
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 […]
A new generation is waiting for the whimsy and wit of Dr. Seuss.
The war machine needs fuel, perhaps so much as to make protecting oil redundant.
From Godzilla to The Unbeatable Squirrel Girl, it’s everywhere.
He goes on and on about ideology, but what does it mean?
Almost all experts agree that coding will become nearly as ubiquitous as literacy in the future. But the nature of coding in the future may be very different.
The famed science fiction author coined the term “cyberspace” before it existed.

In physics, anything that isn’t forbidden must occur. So why don’t the strong interactions violate CP-symmetry? If you ask a physicist what the biggest unsolved problem facing the field today […]
Not only can’t astronomers and planetary scientists agree, but the IAU made it worse for everyone. If you were alive in 2006, you likely remember a momentous event in astronomy: […]
