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 […]
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 […]
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 […]
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 […]
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 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 […]
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 […]
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 […]
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 […]
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 […]
There’s no such thing as a theory that’s too beautiful to be wrong, if it doesn’t agree with experiment. The history of physics is filled with great ideas that you’ve […]
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 […]
There have been a lot of public advocates from the “no dark matter” camp, getting lots of popular attention. But the Universe still needs dark matter. Here’s why. If you took […]
One of cosmic inflation’s cofounders came out against it, calling it not even science. But it is… and so much more. “There’s no obvious reason to assume that the very same […]
We’ve come so far since 2015; what do we know about dark matter now that we didn’t know then? Back in 2015, the dark matter situation was pretty straightforward: the large-scale […]
A live-blog event happened a week ago, but you can catch the entire thing anew here, right now! “We have never observed infinity in nature. Whenever you have infinities in […]
There’s useful science to be gotten out of it, but most science that mentions it is anything but. “There is a voice inside of youThat whispers all day long,‘I feel this […]
Even if the Universe grows to infinity, there might not be enough space to hold all the possibilities. “We are actually living in a million parallel realities every single minute.” –Marina […]
If you’re looking for a point in space, the answer is going to shock you. “The world you see, nature’s greatest and most glorious creation, and the human mind which gazes […]
Before the Big Bang… after the Big Freeze… will everything look the same? “What is wild cannot be bought or sold, borrowed or copied. It is. Unmistakeable, unforgettable, unshamable, elemental as […]
And can we even agree on the definition of ‘nothingness’? “Alone, I often fall down into nothingness. I must push my foot stealthily lest I should fall off the edge […]
Not the show, the actual scientific theory itself! “Gamow was fantastic in his ideas. He was right, he was wrong. More often wrong than right. Always interesting; … and when his idea […]
Now that LIGO’s found two pairs of merging black holes, what does the future hold? “We shall not cease from exploration, and the end of all our exploring will be to […]
It’s an old idea made new again, but it just might fall apart. “[The black hole] teaches us that space can be crumpled like a piece of paper into an infinitesimal […]
If there is a quantum theory of gravity, is String Theory the only game in town? “I just think too many nice things have happened in string theory for it to […]
Science is the best tool we have for predicting the future. Here’s what the next year ought to bring. “For last year’s words belong to last year’s language And next year’s […]
Throwback Thursday: How Dark Matter’s #1 Competitor Died The only way out is to modify the laws of gravity, and our best observations rule those modifications out. “The discrepancy between […]
