It’s the best-known transcendental number of all-time, and March 14 (3/14 in many countries) is the perfect time to celebrate Pi (π) Day!
The Big Bang was hot, dense, uniform, and filled with matter and energy. Before that? There was nothing. Here’s how that’s possible.
SpinLaunch will cleverly attempt to reach space with minimal rocket fuel. But will physics prevent a full-scale version from succeeding?
The universe is only 13.8 billion years old, but we can see back 46.1 billion light-years. Here’s how the expanding universe does it.
Undiagnosed brain disease or divine inspiration? The origins of the French composer’s most provocative composition remain up for debate.
Everyone has pondered what they would do with an extra hour a day. Would they get more sleep or spend more time with family? Spend time on a side project […]
Puerto Rico’s iconic telescope facilitated important scientific discoveries while inspiring young scientists and the public imagination.
Yes, we’d all die. But for 21 minutes, we’d have the ride of a lifetime. One of the most remarkable facts about the Universe is this: in the absence of […]
The first nation to make bitcoin legal tender will use geothermal energy to mine it.
Democritus also did not believe in free will but was still known as the “laughing philosopher.”
A new study looks at what happens when you get infected with two viruses at the same time.
Often called modern-day dinosaurs, cassowaries are one of only a few birds known to have killed humans.
Discover the history of homemade sugar skulls, home altars, and fantastical spirit animals.
Three of our dimensions are spatial and one is temporal, but could there be more? From any point in space, you are free to move in any direction you choose. No […]
How we’re seeing black holes as never before… and a whole lot more. It was only back in the early 2000s that scientists were struggling to identify and weigh the small […]
No matter how good our measurement devices get, certain quantum properties always possess an inherent uncertainty. Can we figure out why?
Time always moves in the same direction, but what if the Universe were contracting? As we step forward in time, a number of things always seem to happen together. Objects […]
After 20 months, scientists find lab-dish brain cells matured at a similar rate to those of an actual infant.
For the first time, light that comes from behind a black hole has been spotted.
Your inner voice can be the devil on your shoulder or the angel. It depends on where your focus lies.
In our common experience, you can’t get something for nothing. In the quantum realm, something really can emerge from nothing.
Artist Seán Doran recently created more than eight hours of high-definition video using images captured by Japan’s SELENE lunar orbiter.
Shame is a powerful tool that must be used with care.
It’s 92 billion light-years wide after just 13.8 billion years. And that’s just fine. If there’s one rule that people know about how fast things can move, it’s that there’s a […]
Smallpox, Ebola, HIV, influenza, the plague, malaria, and a whole host of terrible bacteria, viruses, fungi, and parasites were cooked up by Mother Nature, all on her own. Apparently, Mother Nature hasn’t banned gain-of-function research.
Life is possible because of asymmetries, such as an imbalance between matter and antimatter and the “handedness” (chirality) of molecules.
With sodium-sensitive eyes, we’d see it every new Moon. With no detectable gases, the Moon appears to be atmosphere-free. The Moon as seen from a view above the majority of Earth’s […]
Was this a moment when humans interbred with Neanderthals?
At a fundamental level, nobody knows whether gravity is truly quantum in nature. A novel experiment strongly hints that it is.
