Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
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 […]
The latest challenger to dark matter’s throne may not be so difficult to knock off, after all. This post was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in […]
You may have heard of Laniakea, but don’t count on it being real. “It’s the gravity that shapes the large scale structure of the universe, even though it is the weakest […]
And England almost burned themselves down as a result. “When Benjamin Franklin inveted the lightning rod, the clergy, both in England and America, with enthusiastic support of George III, condemned it […]
But are any of these potentially Earth-like worlds actually inhabited? Here are the prospects. “It isn’t only the beauty of the night sky that thrills me. It’s the sense I […]
