Every physical theory has constants in it. The gravitational constant is remarkably uncertain. When we first began formulating physical laws, we did so empirically: through experiments. Drop a ball off […]
Anchorage was rocked by back-to-back earthquakes on Friday morning, prompting a tsunami warning.
When two different techniques give two different results, either someone is wrong, or something incredible is happening. Imagine you were a scientist attempting to measure some property of the Universe. […]
The incredible story of a scientist who survived gulags, fighting to change his country and physics.
The quest for a quantum theory of gravity is the holy grail of physics. Here’s why it’s murkier than anyone expected. If you want to fully describe how the Universe […]
Two massive clouds of dust in orbit around the Earth have been discussed for years and finally proven to exist.
We speak about it, argue over it, and even fight wars for it. We know it when we see it. But just what is energy, anyway? When it comes to being […]
A new poll highlights the dramatic influence of partisan thinking in the U.S. with regards to key principles of international law.
The Universe was born matter-antimatter symmetric. Here’s what happened when the last of our antimatter disappeared. Things happen fast in the earliest stages of the Universe. In the first 25 […]
Forget the speed of light or the electron’s charge. This is the physical constant that really matters. Why is our Universe the way it is, and not some other way? There […]
This is a remarkably rare case of non-human primate tool use in the wild. We’re witnessing another species dawn of their Stone Age.
Ever since we’ve had the technology, we’ve looked to the stars in search of alien life. It’s assumed that we’re looking because we want to find other life in the universe, but what if we’re looking to make sure there isn’t any?
What do guns, roses, and Guns N’ Roses have in common? They’re all awesome. And all of them are in our weekly random fact roundup.
The Satanic Temple unveiled a statue of the occult idol Baphomet outside the Arkansas State Capitol building on Thursday to protest the Ten Commandments monument already on capitol grounds.
Karen Michels video on the dangers of coconut oil has gone viral, leaving the nutritional blogosphere scratching its head.
The Lawrence Livermore National Laboratory has been working for years to preserve the estimated 10,000 videos of nuclear bomb tests made by the U.S. government during the Cold War.
Dark matter is one of the most puzzling, unintuitive concepts in all of physics. But we still need it. Our Universe isn’t like us. While we’re made of atoms, and other […]
It’s not simply Hubble’s Law anymore, but the real history is far more complex than the stories you’ve heard. One of the most mind-blowing facts in our existence is that space […]
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 […]
If we know how big the observable Universe is, why can’t we figure out how big the unobservable part is? 13.8 billion years ago, the Big Bang occurred. The Universe was […]
Think you make moral judgments objectively? Think again.
Good news for space exploration?
When it comes to the Solar System, all we have left are the survivors. At last, that might be enough to know what happened 4.5 billion years ago. We know what […]
Researchers at MIT and Harvard Medical School have developed a tattoo ink that could potentially be used to monitor medical conditions, with ink that changes in response to physical conditions.
The accelerated expansion of the Universe is one of the greatest puzzles today. Could this out-of-the-box idea explain it without dark energy? When it comes to our quest to understand the […]
Startups create the tech and products that set the tone for our collective future. It’s pivotal that founders lead by example to make diversity and inclusion a priority—and reap the rewards.
Before there were humans, planets, or even stars and galaxies, we had to make the first elements. Here’s how they happened. From the first moments of Big Bang to the […]
A classic essay defines different ways to disagree, from the worst to the best, with lessons that ring true in our divisive times.
