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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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, […]
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 […]
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 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 […]
Elite organizations tend to get conspiracy theorists going.
Our Universe is 13.8 billion years old, and our Sun formed about 2/3rds of the way through. Here’s what came before it. When it comes to the great cosmic question of […]
We see matter, but not antimatter, in our Universe. Could black holes be the answer? One of the greatest cosmic puzzles in our entire Universe is why there’s so much more […]
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 […]
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 […]
And you don’t even need a Delorean at 88 MPH. It’s one of the greatest tropes in movies, literature, and television shows: the idea that we could travel back in time […]
Illumination from nanobionic plants might one day replace some electrical lighting.
Spoiler: it isn’t the end of the Universe, and it’s not likely to lead to new evidence for the Multiverse, either. On March 14, 2018, the most famous and celebrated […]
Our dark matter searches have yet to yield a robust detection. Could we be looking in all the wrong places? There’s perhaps no more fundamental question to ask than, “what is […]
It’s the first, most naive question you might think to ask. The solution is a lot more complicated than you imagine. According to a large amount of evidence, the overwhelming majority […]
If nature makes equal amounts of matter and antimatter, how are we here? When you look out at the vastness of the Universe, at the planets, stars, galaxies, and all there […]
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, […]
