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 […]
The laws of physics aren’t changing. The Earth is. When it comes to any physical science, we know that the fundamental rules governing how the Universe works remain constant with time. […]
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 […]
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 […]
The history of the Universe is forever imprinted in our own bodies. We can learn a lot about the history of the Universe just by looking at each of our own […]
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. […]
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 […]
The definitive answer requires better, unbiased data. Despite all the advances that have occurred in human history, one extraordinary puzzle still remains right in our own backyard: we aren’t sure how […]
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 […]
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 […]
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 […]
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 […]
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, […]
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 […]
NASA’s New Horizons is the most distant technologically advanced observatory ever. And that makes all the difference. When you look at an object that’s very distant from you, how well […]
But few critics actually addressed the science on climate change.
If they saw us as we were before the recent industrial revolution, would there be any reason to particularly care about us? All across the Universe, trillions of galaxies can be […]
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 […]
The top of Mauna Kea is the ideal physical site for this new, ready-to-be-built telescope. But that’s far from the only concern. For many years, astronomers have looked forward to a […]
In line with his own ingrained assumptions, the standard ones of Victorian England, Darwin maintained that female inferiority is an inescapable consequence of nature.
These ten characters have all had a huge influence on psychology. Their stories continue to intrigue those interested in personality and identity, nature and nurture, and the links between mind and body.
North Korea’s statements, actions, and the physics of how to do it all point to the same terrifying conclusion. There are few things in this world that have the capability […]
BICEP2 scientist Brian Keating’s new book is honest and insightful, but just as notable for what it fails to recognize. Imagine what it’s like to be a scientist working on […]
Intelligent aliens, if they exist in the galaxy or the Universe, might be detectable from a variety of signals: electromagnetic, from planet modification, or because they’re spacefaring. But we haven’t […]
If dark energy were stronger or weaker, everything would be pretty much the same. And that’s a puzzle. After the Big Bang, the Universe was full of matter and radiation. It […]
Including where to go, and when, for the most spectacular views. Against the backdrop of a dark, clear night sky, you can see the Moon, planets, stars, the Milky Way, […]
Distances in the expanding Universe don’t work like you’d expect. Unless, that is, you learn to think like a cosmologist. There are a few fundamental facts about the Universe — its origin, […]
The differences between what you are and what you could be are stunning. The human body consists of somewhere around 1028particles, all bound together. The typical human has a mass […]
It isn’t the rapture or some crazy prophesy, but science, that tells us when and how the end will come. “The surface of the Earth is the shore of the cosmic […]
