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 […]
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 […]
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 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 […]
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 […]
Elite organizations tend to get conspiracy theorists going.
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 […]
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 […]
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 […]
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 […]
Did they perform their analysis sub-optimally? Maybe. But gravitational waves were seen no matter what. “We hope that interested people will repeat our calculations and will make up their own minds […]
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 […]
It’s the most fundamental fabric of the Universe itself. But how does it work? “‘Space-time’ — that hideous hybrid whose very hyphen looks phoney.” –Vladimir Nabokov When it comes to understanding the Universe, there […]
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 […]
More than a million times what we make at the LHC, these could be the ultimate keys to nature. “Energy is liberated matter, matter is energy waiting to happen.” –Bill Bryson […]
Last week’s $1.5 billion jackpot was a record that likely will be broken again and again. But when, if ever, should you play? “I’ve done the calculation and your chances of […]
They’re judged to be “standard candles” and the greatest cosmic distance indicators. What if they’re not so standard? “It’s everywhere, really. It’s between the galaxies. It is in this room. […]

Do schools kill creativity? Should white boys ever rap or breakdance? This week on Think Again we're joined by Maria Konnikova, author of The Confidence Game and Mastermind: How to Think Like Sherlock Holmes
Is everything astonishingly simple, though? Or is this a grandiose claim that falls flat when confronted with the evidence? “My main interest is the problem of the singularity. If we […]
But especially for anyone who listened to your “Celebration of Creation” speech. “In science it often happens that scientists say, ‘You know that’s a really good argument; my position is […]
Our observable Universe is finite, and so is the amount of information in it. Here’s what we may never know. “Despite its name, the big bang theory is not really […]
Why the argument that “this idea is absurd” is no argument at all. “He who loves practice without theory is like the sailor who boards ship without a rudder and […]
No matter how great your expertise, new discoveries await for the curious. “There is no end to education. It is not that you read a book, pass an examination, and […]
We’ve only ever seen 2nd-generation stars and later. Until, just maybe, now. “For my part I know nothing with any certainty, but the sight of the stars makes me dream.” […]
