Was This the Geekiest Concert of All Time?

When the hamburger-shaped spaceship with the word “Millennium” on the back lowered down above me, I figured I was in for something special. What I didn’t expect was that, for the next two hours, the “Millennium…” let’s call it “Falcon,” would fly through an asteroid field before docking on a planet with light cycles and noir landscapes, as lines of code dropped down like rain and huge cylindrical gates of stars swirled around. But that’s what happened, and, I must say, it was phenomenal. Last w

The most otherworldly, mysterious forms of lightning on Earth

Our atmosphere is like one big electrical circuit: Thunderstorms are the batteries that charge it up, and lightning is the current flowing through it. On the ground we see evidence of this circuit when lightning cracks and strikes the ground, or when it lights up deep inside a thundercloud, but high above the clouds lies a secret electrical zoo full of sprites, elves, and jets. These fantastical terms refer to light displays called transient luminous events or TLEs that occur in Earth’s upper a

New sphere-packing record stems from an unexpected source

The advantage of Rogers’ method was that you didn’t have to start with a particularly efficient lattice to get an efficient sphere packing. You just had to choose the right ellipsoid. But this introduced a new complication. Unlike a sphere, which is completely defined by a single number — its radius — an ellipsoid is defined by several axes of different lengths. The higher the dimension, the greater the number of directions you can stretch your ellipsoid in, and the more options you have for wha

‘The Wizard of Oz’ at the Sphere Tests the Ways AI Can Preserve Classic Cinema

The Wizard of Oz is landing on the Vegas strip at the Sphere this summer, and it’s not without some controversy. The Warner Bros. classic Technicolor feature starring Judy Garland is being presented in a special limited engagement at the massive spherical stadium venue in Las Vegas, presumably in between music artist residencies. The state-of-the-art immersive entertainment center made its debut as a must-visit attraction with rock band U2. Now in a new venture, the Sphere collaborates with Wa

What Problems to Solve (1966)

What Problems to Solve - By Richard Feynman A former student, who was also once a student of Tomonaga’s, wrote to extend his congratulations. Feynman responded, asking Mr. Mano what he was now doing. The response: “studying the Coherence theory with some applications to the propagation of electromagnetic waves through turbulent atmosphere… a humble and down-to-earth type of problem.”

NASA's Voyager Found a 30k-50k Kelvin "Wall" at the Edge of Solar System

In 1977, NASA launched the Voyager probes to study the Solar System's edge, and the interstellar medium between the stars. One by one, they both hit the "wall of fire" at the boundaries of our home system, measuring temperatures of 30,000-50,000 kelvin (54,000-90,000 degrees Fahrenheit) on their passage through it. There are a few ways you could define the edge of the Solar System – for instance, where the planets end, or at the Oort cloud, the boundary of the Sun's gravitational influence wher

Anysphere launches a $200-a-month Cursor AI coding subscription

Anysphere launched a new $200-a-month subscription plan for its popular AI coding tool, Cursor, the company announced in a blog post on Monday. The new plan, Ultra, offers users 20x more usage on AI models from OpenAI, Anthropic, Google DeepMind, and xAI compared to the company’s $20-a-month subscription plan, Pro. Anysphere also says Cursor users on the Ultra plan will get priority access to new features. Anysphere CEO Michael Truell said in a blog that the Ultra plan was made possible throug

Scientists Reveal Easy Three-Step Plan to Terraform Mars

Terraforming, the act of radically transforming a planet's climate and environment to make it suitable for human habitation, currently belongs to the realm of science-fiction. But it's possible, at least in theory, and the idea of terraforming our nearest candidate planet for off-world colonization, Mars, has captivated us for generations. But how would we even begin to pull off such a monumental feat of engineering? You can basically boil it down to three simple steps, argue the authors of a r

Astronomers create first 3D map of a hellish alien planet's atmosphere

The big picture: Nearly 6,000 exoplanets have now been confirmed in the vast expanse of the Milky Way galaxy. Some are believed to have the potential to harbor life, while others are so hostile that they make Venus seem mild by comparison. One such planet is the ultra-hot Jupiter known as WASP-121b, nicknamed Tylos – a world so extreme it defies expectations. Located around 900 light-years away in the Puppis constellation, Tylos orbits its parent star at an absurdly close distance, completing a
