Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
You lose whether you use protons or electrons in your collider, for different reasons. Could the unstable muon solve both problems? “It does not matter how slowly you go as […]
Its 18 large, segmented golden mirrors aren’t even the whole story. But how much gold is really in there? “Hey, if our eyes could access the infrared part of the light […]
With liquid water, an energy source, and the perfect raw ingredients, Enceladus might be the holy grail we’ve been seeking. This article is written by contributing author Jesse Shanahan. Jesse is […]
We’ve never seen an event horizon, nor directly imaged a black hole. Thanks to a worldwide effort, victory may at last be in sight. “Never look down to test the ground […]
If it’s the anti-version of normal matter, could it possibly fall “up”? This article was written by Sabine Hossenfelder of Backreaction. Sabine is a theoretical physicist specialized in quantum gravity and […]
And how if you try this with someone shorter than you are, you’ll find it extra convincing! “I drive from Florida to California all the time, and it’s flat to […]
What would energy without a particle to attach itself to even look like? “It is only through labor and painful effort, by grim energy and resolute courage, that we move on […]
If you think federal funding for science is expensive, wait until you see the cost of not funding it. “For me, it is far better to grasp the Universe as […]
The answer lies billions of years in the past. “Dark matter or invisible element?You decide.” –Toba Beta When we look out at the luminous matter in the Universe — stars, galaxies, clusters of […]
You know how bright the full Moon is. Well, from the Moon, how would the ‘full Earth’ compare? “I put up my thumb and shut one eye, and my thumb blotted […]
We claim it’s the leftover glow from the Big Bang, but where is this light actually coming from? “We are told to let our light shine, and if it does, we […]
If you heard about time crystals, be aware that they do exist. But learn what they mean. “Every particular in nature, a leaf, a drop, a crystal, a moment of time […]
Space is getting bigger, but atoms, humans, Earth and our Milky Way stay the same size. How is this possible? “The Universe is expanding the way your mind is expanding. […]
Your theory predicts something novel? How nice. But no one will pay you any mind unless you test it. “He who loves practice without theory is like the sailor who boards […]
Have you heard that life is unlikely around low-mass, red dwarf stars? It might be time to rethink that flawed conclusion. “Laws of nature mixed with evolutionary/historical contingencies allow for […]
There’s a lot to learn about other worlds, but you can’t learn it all without looking up. “One should not need a teleportation device to decide whether a newly discovered object […]
With James Webb and WFIRST launching soon, the Universe can expect a revolution. But what will it look like? “For the first time we can learn about individual stars from near […]
The red planet once wasn’t so different from Earth. Here’s what happened. “Mars’ atmosphere is so thin, you do not need a lot of streamlining. By the time the ship […]
We take for granted how much the Moon does for Earth, but not all of the changes would be bad. “If we get rid of the moon, women, those menstrual cycles […]
A live-blog event of an incredible public lecture by a scientist on the inside of James Webb’s team. “The [James Webb] telescope is basically designed to answer the big questions in […]
