If you ask your maps app to find "restaurants that aren't McDonald's," you won't like the result.
It’s how successful our current theories are. Some 500 years ago, there was one scientific phenomenon that was, without controversy, extremely well-understood: the motion of the celestial objects in the sky. […]
All scientific theories, at some level, are wrong. That’s why consensus is so vital. There are two important and common words that, when used scientifically, have a very different meaning than […]
Deniers will never stop misleading others. Here’s the truth. Every so often, advocates of a fringe theory — one that doesn’t fit the evidence as well as the mainstream theory — do what they can […]
Demanding appropriate levels of skepticism and scrutiny isn’t cruelty, but rather demonstrates scientific integrity and intellectual honesty. Every few months, a novel headline will fly across the world, claiming to […]
The Big Bang is our accepted origin of the Universe. But is there another possibility? Since the mid-1960s and the discovery of the Cosmic Microwave Background, the Big Bang has […]
Forgetting them, at any step, can lead to unscientific conclusions. No one, not even the smartest among us, were competent scientists from the outset. The concept of science is simple […]
Enough mass in one location will always create a black hole. But not all masses are possible. If you take enough mass and compress it into a small enough volume […]
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 […]
When one group says “A” and another group says “B,” consider that everyone might be wrong. One of the biggest enemies of scientific truth is the setup of a false dichotomy. […]
It’s not a gambit. It’s not fraud. It’s not an opinion. And it’s not biased like you think it is. Most of us, when we think about what science is, default […]
Almost certainly not. Here’s the science of why. The Universe, as we know it, simply doesn’t add up. On the one hand, we can look out on a cosmic scale and […]
And what might we learn as we collect new, never-before-seen data? If you took one of history’s top scientists from 100 years ago and dropped them into today’s world, what […]
What we’ve seen isn’t necessarily what we get, but the most common world doesn’t look like ours. There’s a very common myth out there in astronomy: the idea that the Sun […]
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 […]
If we want our conclusions to be meaningful, our data had better be robust. When it comes to the Universe, there’s a whole lot that doesn’t add up. All the matter […]
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 […]
A single lifetime is more than enough to take you to the limits of the Universe. Right now, there are only three things limiting how far our spacecrafts can take […]
There are exposed planetary cores orbiting stars, and we may have already found them. When we take a look at the planets in our Solar System, there’s a pretty clear difference […]
We might live in a quantum Universe, but we’ll violate the principle of relativity if space is discrete. If you try and divide matter into smaller and smaller chunks, you’ll […]
Zeno’s paradox stumped philosophers, mathematicians, and intellectuals for millennia. It took physics to finally solve it. The fastest human in the world, according to the Ancient Greek legend, was the heroine […]
Don’t miss the summer’s greatest natural sights of all. Some of the natural highlights of our night sky are easy to overlook. Every year, you’ll hear about some of the brightest, […]
Scientific surprises are often how science advances. But more often than not, they’re just bad science. When you’re a scientist, getting an unexpected result can be a double-edged sword. The best […]
It’s true that we have a thermodynamic arrow of time, and entropy always increases. But that can’t explain what we perceive. One of the enormous conceptual ideas that came along […]
The bid to buy Greenland is unlikely to become seriously considered.
She’s not a scientist, an expert, or even an adult. But she’s got one good lesson to teach us all. Like most people on Earth, Greta Thunberg is not a climate […]
It might seem puzzling, in a Universe bound by the speed of light, that this could be true. Here’s the science behind it. If you look out into the distant Universe, […]
As soon as you start thinking about energy and gravity, you’ll realize the need to go beyond it. When it comes to a science like physics, theoretical expectations must always be […]
The age of the Universe is only 13.8 billion years, but we know that protons survive much longer. Here’s how. Since the discovery of radioactivity in the 19th century, humanity has […]
