The highest energy collisions go beyond any collider… and may hold a fantastic secret! This article was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity. […]
The Perseid meteor shower is coming, which may put you in the mindset to wonder “What causes a meteor shower?”
It’s the most mysterious “stuff” our Universe has. So why are we so sure it’s real? “The Universe is made mostly of dark matter and dark energy, and we don’t know […]
Can we work out what ingredients could make “free will” work? Here’s a map of some of the steps it would need.
We have every reason to believe gravity is an inherently quantum theory. Here’s how we’ll prove it once and for all! The following article was written by Dr. Sabine Hossenfelder. Sabine […]
A Washington think tank raises concerns that U.S. nuclear weapons stored at a military base in Turkey can fall into the wrong hands.
It took hundreds of years for Einstein to dethrone him, and even then, he was off by less than 1% of a spectacular prediction.
Researchers discover the source of a remarkably strange sound coming from the Caribbean.
Everything we know about gravity suggests the universe should expand at a decelerating rate, but the opposite is true says Christophe Galfard, Stephen Hawking’s protege.

And defeat for new physics. Without something spectacular, there’s no reason to build a bigger collider. “There is nothing new to be discovered in physics now. All that remains is […]
Could the Universe have been born completely uniform and still given rise to us? “First, you should check out my house. It’s, like, kinda lame, but way less lame than, like, […]
Understanding the shape of the Earth is all about its mass, says Bill Nye the Science Guy. If it weren’t for all the water, rocks, metals, and lava on our planet, it might have an irregular form.

Should George Clooney’s character have floated away? Or do the laws of physics tell a different story? “You’ve got to learn to let go.” –Matt Kowalski, Gravity The movies play […]
Learn why you shouldn’t take a selfie in zero gravity, and other aspects of living in space.
How we know some galaxies have more than others. “Motions of the stars tell you how much matter there is. They don’t care what form the matter is, they just tell […]
The present story is only the beginning; there’s a revolution coming! “Our existence in this place, this microscopic corner of the cosmos, is fleeting. With utter disregard for our wants […]
What narrow misses did NASA’s Juno probe face on the five-year journey to Jupiter, and it’s acrobatic slip into the orbit of our solar system’s largest planet?
Why Everest and the Grand Canyon are so small. Yes, SMALL! “How well I have learned that there is no fence to sit on between heaven and hell. There is a […]
When you get enough mass together, Einstein’s theory of gravity causes space to act like a lens. Here are the results. “The first amazing fact about gravitation is that the ratio […]
Now that it’s seen gravitational waves, could physics beyond Einstein be its next target? This post is written by Sabine Hossenfelder, a theoretical physicist specialized in quantum gravity & high energy […]
The answer depends on what scales you’re looking at. “The world is the great gymnasium where we come to make ourselves strong.” –Swami Vivekananda When it comes to the fundamental laws […]
It’s said to be the majority of matter in the Universe, but how sure are we of that? “For the moment we might very well call them DUNNOS (for Dark Unknown […]
And could what we see over there spell disaster for Earth? “An asteroid or a supervolcano could certainly destroy us, but we also face risks the dinosaurs never saw: An engineered […]
Why, even with infinite magnification, we’d never view the first stars. “Dwell on the beauty of life. Watch the stars, and see yourself running with them.” –Marcus Aurelius Imagine the […]
And if it were, is there any way we could detect that this were the case? “Do I believe, for example, that by using magic I could fly? No. How would […]
A correlation between normal matter and the observed rotation suggests that maybe dark matter isn’t a certainty, after all. “Nothing in the standard cosmological model predicts this, and it is almost […]
If you were betting on LIGO, you bet wrong. Just like everybody else. “‘Topology is destiny,’ he said, and put the drawers on. One leg at a time.” –Neal Stephenson One […]
Could the Nobel Prize of 2011 have been awarded without cause? “Even if I stumble on to the absolute truth of any aspect of the universe, I will not realise my […]
Some things are held to a higher standard than mob rule. “The evidence at present available points strongly to the conclusion that the spirals are individual galaxies, or island universes, […]
