Among the general public, people compare it to the aether, phlogiston, or epicycles. Yet almost all astronomers are certain: dark matter and dark energy exist. Here’s why. If you go by […]

Our best physical theories predict that a multiverse exists. But if we can’t test it, is it really scientific? The Universe is all there ever was, all there is, and […]
The Boomerang Nebula, in our galaxy, is even colder than completely empty space. Here’s how that’s possible. Imagine the coldest place you possibly can. Inside it, the particles that make […]
Of all the experiments performed and measurements made involving fundamental particles, none has ever violated the Standard Model. Until now. If there’s one thing you can count on physicists for, it’s […]
Getting a good night’s sleep just took on a whole new meaning.
Einstein’s explanation is the only one that works. When Newton first proposed the law of universal gravitation, it marked the very first time that we realized the same rule governing how […]
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 […]
They’re at a higher risk for depression, weekend binge drinking, and unnecessary dieting.
The best books, calendar, accessories and more are all just one click away. Every year, there are no shortage of wonderful, exciting, informative gifts you could get for those who matter […]
The Israeli historian has plenty to say.
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 […]
LIGO, here on Earth, has exquisitely-precise distances its lasers travel. With three spacecrafts in motion, how could LISA work? Since it began operating in 2015, advanced LIGO has ushered in an […]
Signals from rare black hole-neutron star pairs could pinpoint rate at which universe is growing, researchers say.
Quantum particles are mysterious and difficult to track down, but neutrinos may be the most elusive quantum particles yet. The facilities designed to observe neutrinos are feats of engineering, and what they hope to uncover is profound.
Explosives sent to addresses linked to former Vice President Joe Biden and actor Robert De Niro were similar to bombs delivered to other political figures this week, officials said.
Our future fate is likely already determined. If we end in a Big Crunch, what does that mean? The ultimate fate of the Universe is one of the biggest existential questions […]
Despite its prominence in our collective imagination, variations in metabolism play a minor role in obesity.
The expanding Universe really is accelerating, and no dusty scenario can explain it. 20 years ago, our understanding of the Universe underwent a revolution. For generations, we had known the Universe […]
Here are four separate ways you can prove it, even 50 years after-the-fact. 50 years ago, on July 20, 1969, humanity took our first footsteps on the surface of another […]
Our motion through space is undeniable. So why can’t we feel it? Our planet isn’t the stationary place we feel it to be beneath our feet, but rather moves in an […]

If dark energy is causing the Universe to disappear, how can we still find and see ultra-distant stars and galaxies? In the 1920s, scientists discovered that the Universe was expandingbased […]
The answer has nothing at all to do with the Higgs boson. In this Universe, there are very few fundamental properties that cannot be derived from something simpler. The rules governing […]
Gravity and time are so different from what you’d expect. Here’s how it all would end. If you could only know the answer to one question about the Universe, what would […]
We can go to deeper and deeper levels, finding more fundamental quantities as we do. But is there a truly fundamental quantity? What is the Universe, at a fundamental level, […]
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 […]
Scientists have discovered that neurological response to posture is separate from movement.
Perhaps energy isn’t conserved at all in an expanding Universe. If you have a Universe full of stuff — whether that’s atoms, dark matter, radiation, neutrinos, or anything else — it’s virtually impossible to […]
