They say that atoms are mostly 99.99999% empty space. But quantum physics says otherwise. If you were to look at what your body is made of, at smaller and more […]
You never know what you’re going to find when you look somewhere new for the first time. Approximately 4600 feet (1400 meters) underground, beneath the Italian mountain known as Gran Sasso, […]
All the things that surround us and make us up weren’t always here. But where did it all come from? The Universe, as we see it today, sure is full of […]
Surrounding Earth is a powerful magnetic field created by swirling liquid iron in the planet’s core. Earth’s magnetic field may be nearly as old as the Earth itself – and […]
The center of our Sun tops out at 15 million K, but nuclear bombs can get nearly 20 times hotter. Here’s how. In terms of raw energy output, nothing on our […]
We eat 50 billion chickens every year. Is there a better way?
Humans are more likely to have “first contact” with an advanced alien civilization, according to a recent NASA-funded paper.
It is impossible for science to arrive at ultimate truths, but functional truths are good enough.
Whose responsibility is it to ensure that there is affordable access to employment?
A year of disruptions to work has contributed to mass burnout.
It rotates on its axis, revolves around the Sun, moves throughout the Milky Way, and gets carried by our galaxy all throughout space.
You’ve spent almost a decade gaining extremely specialized skills. But that’s ok; your value is greater than you realize.
A black woman most have never heard of made GPS possible. Over the span of a single lifetime, the world has changed in ways that would have been virtually unimaginable […]
Society-changing ideas form through a three-stage process, argues author Michael Bhaskar.
When two black holes that shouldn’t exist are seen merging, physics has some explaining to do. After years of searching for gravitational waves, it finally happened: LIGO bagged the biggest one […]
How do these little beasties detect light anyway?
Researchers design microdevices that can gradually deliver medicine by latching on to intestines.
There’s some amazing science happening at the South Pole, but some very grandiose claims being made. What’s actually going on? For some of us, the idea of parallel Universes spark our […]
The British economic anthropologist Jason Hickel proposes “degrowth” in the face of recession.
Both made monumental contributions that were far ahead of their time. It’s hard to believe, but the idea that the Universe was dominated not by normal matter but rather by dark […]
It’s massive, it’s transparent, and it’s ubiquitous. But so is our ignorance. When we look out at the Universe, we have two general ways to try and make sense of […]
Have we already found dark matter? It may be hiding in existing data, says a study.
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 most massive nearby stars could be the seeds our supermassive black holes need. The problem with the Universe, as we see it today, is that we only get a snapshot […]
By delving into the mysteries of the Universe, colliders have entered the Zeitgeist and tapped the wonders and fears of our age.
It’s something most adults don’t understand very well. So what should you tell a child? If you’ve ever had a conversation with an inquisitive, curious child, you might have experienced that […]
We just observed the first ‘lunar formation’ in an exoplanetary system. This one image, above, is the first to show moons actively forming around a planet. This colourful image shows […]
As it turns out, people who can afford to fly all the time use more energy than anybody else.
