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 […]
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 […]
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 […]
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 […]
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 an incredibly useful approximation. But the truth takes us far deeper. Anyone who’s ever taken a physics course has learned the same myth for centuries now: that any object thrown, […]
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, […]
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 […]
Truth is, dinosaurs aren’t as distinct as you may think, but to find out why, we first have to consider how we got the term “dinosaur.”
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 […]
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 […]
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 […]
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 […]
If your favorite theory made the list, you might want to consider a new favorite to bet on. “Some people believe holding on and hanging in there are signs of great […]
Could there be a massive, giant planet beyond Neptune? Here’s what the science says… for now. “Finding out that something you have just discovered is considered all but impossible is one […]
Gravitational waves and electromagnetic ones don’t need to go together. But physics says it’s possible; what do the observations say? “The black holes collide in complete darkness. None of the […]
What it means that 2016 is the hottest year on record. “There are now dozens of hockey sticks and the all come to the same basic conclusion. The recent warming does […]
No one is right 100% of the time. Even the greatest genius of all. “The only man who never makes a mistake is the man who never does anything.” –Theodore Roosevelt […]
If you “know” the answer before you ever begin, you might as well not even try. “I have difficulty to believe it, because nothing in Italy arrives ahead of time.” –Sergio […]
If you think you can just take a test and demonstrate your scientific literacy, think again. “Through basic science literacy, people can understand the policy choices we need to be making. […]
It may be the only way to save the USA — and the world — from alternative facts. “If your experiment needs statistics, you ought to have done a better experiment.” –Ernest Rutherford There […]
That’s not how probability works. Or asteroids, for that matter. “Bringing an asteroid back to Earth? What’s that have to do with space exploration? If we were moving outward from there, […]
Gravity is the oldest fundamental force ever discovered. Might it not be fundamental after all? “The whole edifice of modern physics is built up on the fundamental hypothesis of the atomic […]
Could the Nobel Prize of 2011 have been awarded without cause? “Even if I stumble on to the absolute truth of any aspect of the universe, I will not realise my […]
The way to greatness requires us to look forwards, not backwards. “Whenever I found out anything remarkable, I have thought it my duty to put down my discovery on paper, […]
“Eureka!” is not always as powerful as “that’s what I thought!” “Reality is what kicks back when you kick it. This is just what physicists do with their particle accelerators. […]
Some things are held to a higher standard than mob rule. “The evidence at present available points strongly to the conclusion that the spirals are individual galaxies, or island universes, […]
Everything depends on it, and yet we don’t know it as well as we’d like! “Exploration is in our nature. We began as wanderers, and we are wanderers still. We have […]
