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 […]
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 […]
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 Crab Nebula goes back to 1054, opening a window into our cosmic past. On July 4, 1054, Chinese astronomers recorded a “guest star” in the Taurus constellation. A ‘guest star’ […]
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 […]
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 […]
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 […]
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 […]
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 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 […]
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 […]
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 […]
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 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 […]
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 […]
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 […]
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 […]
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 […]
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, […]
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 […]
In the aftermath of everything we’ve learned about what’s in the Universe, we can make much better estimates of how many alien civilizations are out there. In 1961, scientist Frank Drake […]
All of this has happened before… but not like this! As the year draws to a close, we approach a very special time of year, at least from an astronomical perspective. […]
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 […]
Oregon, Idaho, and Wyoming are all on fire, and simply driving your car can be the most dangerous thing of all. “I’d rather fight 100 structure fires than a wildfire. With […]
No other object this large has come so close to Earth in millions of years. In the 5th millennium, we might suffer the consequences. “Honestly, if you’re given the choice […]
