The laws of physics are not time-reversal invariant. Here’s how we know. No matter when, where, or what you are in the Universe, you experience time in only one direction: forwards. […]

The dominatrix profession demands a mastery of human psychology and the ability to command life’s many challenges.
The dream of multi-messenger astronomy is to seen an event with gravitational waves, neutrinos, and light all together. The newest candidate just might get us there. When it comes to cataclysmic […]
For billions of years, dark energy couldn’t have been detected. Now, it’s everywhere we look. When we look out at the ultra-distant Universe, billion of light-years away, we’re seeing it as […]
The “green” proposal would bring a 21st-century update to the 850-year-old cathedral.
It’s often said that every element was made in a star, but there’s more to it than that.
Gravity gets weaker as the distance squared. But gravitational waves only get weaker as the distance. Why? One of the things we often just accept about the world is that […]
If you traveled in a straight line for far enough, would you come back to where you started? If you were to set out on a journey from anywhere on Earth’s […]
Some galaxies might not have any dark matter. Here’s why you should care. There are two assumptions that everyone makes about the Universe for extremely good reasons, but they might not […]
The nature of our quantum Universe is puzzling, counterintuitive, and testable. The results don’t lie. Although our intuition is an incredibly useful tool for navigating daily life, developed from a lifetime […]
Scientists speculate that if life were to have spontaneously developed on Earth, the first thing there would need to be are vesicles.
Research suggests that people with depression find sad music calming — or even uplifting.
And why Einstein’s quest for unification was doomed from the start. If you wanted to answer the question of what’s truly fundamental in this Universe, you’d need to investigate matter and […]
Unhealthy diets cause the part of your brain responsible for appetite to become inflamed, encouraging further eating and obesity.
On average, American households dump the equivalent of $1,900 worth of food a year.
They said the “missing half” of the Universe’s matter was just found. But what they found barely makes a dent to the big picture. When we look up into the great […]
A new study claims that dark energy is changing with time. Here’s what it would mean, if true. For the past generation, we’ve recognized that our Universe is a particularly dark […]
In reality, it has no color at all. Here’s why. Every time you see an illustration of the COVID-19 coronavirus, it’s shown with a red color to it. Sometimes it’s red […]
As more time passes since the Big Bang, more of the Universe comes into view. But how much? Even though it’s been billions of years since the Big Bang, there’s a […]
Galactic mergers should push gas and dust into the centers of galaxies. So why are these two so quiet? Scientists have studied the closest, largest, brightest galaxies to Earth for centuries. […]
From Godzilla to The Unbeatable Squirrel Girl, it’s everywhere.
It’s not just about SpaceX and Starlink. What we’re deciding today will have a global impact for years and decades to come. For countless millennia, human beings have gazed up into […]
A new method promises to capture an elusive dark world particle.
A star orbiting past our galaxy’s supermassive black hole offered a chance to test relativity as never before. The supermassive black hole at the center of the Milky Way is the […]
Think they all burn through their fuel, die, and leave white dwarfs, neutron stars, or black holes behind? Think again. The day will come when our Sun, like most stars, can […]
Before we formed stars, atoms, elements, or even got rid of our antimatter, the Big Bang made neutrinos. And we found them. The idea of the Big Bang has captivated the […]
If dark matter is fundamentally different from the normal matter we know, there should be a way to test it. Here are the results. Dark matter — despite the enormous indirect evidence for […]
It can supposedly cool you down by 23 degrees Fahrenheit.
Different methods of measuring the expansion rate give different values. This one linchpin is key. In science, different methods of measuring the same properties should yield the same results. The expanding […]
And if they exist, are there alternate-reality versions of you out there, too? You’ve likely imagined it before: another Universe out there, just like this one, where all the random events […]
