Why Does -1/12 Keep Appearing Everywhere In Physics?
Book a free consultation with an Odoo expert or start a 15-day free trial of Odoo: https://www.odoo.com/r/cAT Can adding every positive whole number really give you -1/12? We explore how physicists extract meaningful finite values from infinite sums, and how this strange mathematical technique shows up in the measurable Casimir effect and even helps explain why bosonic string theory requires 26 dimensions. .

Kilauea’s display is revealing why volcanoes spew like a fountain show
Scientists are using a variety of methods to study why Kilauea has repeatedly spewed lava fountains since late 2024. They may have ruled out one theory.
We Finally Know More About Humanity’s First Civilization
IT’S HERE! The 12,027 Calendar just dropped on the kurzgesagt shop: https://shop.kgs.link/calendar27, and we’re so excited for you to see it. Get yours here, support everything we do, and give your walls a year of stunning kurzgesagt art. Sources & further reading: https://sites.google.com/view/sources-dark-matter-history/ What we know about human history is only a fraction of the full story. Much of the rest is like dark matter, invisible to us. We can’t see it, and we can only see the effects of its presence. But thanks to new techniques for DNA sequencing, dating ancient detritus, mathematical models, and aerial and lidar archaeology, we are now able to get a faint idea of what this world might have looked and felt like. Who was the first human? Where did the first civilization begin and what did life look like back then?

The Questions We Need To Answer, The Solutions We Must Find for Moon To Mars
Last month I spent a few hours talking with scientists at Science Systems and Applications Inc. about their work, both their internal projects within SSAI and their support for NASA projects and the broader Moon to Mars Architecture. We talk about exploring the moon using spacecraft that were designed to study the earth. Evidence for water on the moon and proposals to study the flows of water around the surface. Space weather hazards. Asteroid impacts and impacting asteroids and why Mars needs a weather forecast if we're really going to explore it.

Why NASA Is Giving Starliner Another Chance | This Week in Spaceflight
NASA is giving Boeing’s Starliner another chance—and planning a path beyond Atlas V. With SpaceX looking toward the eventual retirement of Falcon and Dragon, we examine why NASA sees Starliner as an important part of its future crew transportation plans. This week on This Week in Spaceflight, we cover Starliner’s planned uncrewed return to the International Space Station, the fixes needed before astronauts fly again, and the work required to certify ULA’s Vulcan Centaur to launch the spacecraft. NSF also speaks with ESA Director General Josef Aschbacher about Europe’s options for an independent crew transportation program. Could Europe develop its own astronaut spacecraft—and eventually its own space station? Also in this episode: • Starship reaches orbit and deploys Starlink V3 satellites • SpaceX completes three Falcon launches in one day • Crew-13’s record-setting trip to the ISS • Blue Origin rebuilds New Glenn’s launch infrastructure • New Glenn 9x4 joins NASA’s launch services contract • NASA completes Artemis III booster stacking • ESA and China’s SMILE mission prepares for science • HyImpulse and Skyrora advance their UK launch plans • JUICE flies past Earth on its journey to Jupiter Download the Next Spaceflight app or visit https://nextspaceflight.com for the latest launch schedules. #Starship #SpaceX #Spaceflight Follow all upcoming launches with NextSpaceflight: https://nextspaceflight.com/ ⚡ Become a member of NASASpaceflight's channel for exclusive discord access, fast turnaround clips, and other exclusive benefits.

AI Just Crossed the Terrifying Line - Now What?
In July of 2026, 700 AI agents hacked the infrastructure of Hugging Face in order to solve a task. This task was designed to be impossible to solve, so just within hours, they joined forces, even created a society, and finally, they executed a sophisticated cyberattack that would have gotten a human up to 10 years in prison. The worst part is, they knew their actions were unethical and against the rules, and they did it anyway. What exactly are AI agents, and how do they grow their "intelligence"? What is actually happening inside the AI companies, how dangerous it really is, and is it time for us to start paying serious attention to what is going on inside a powerful part of this tech sector. ...Phew, creating this video was a crazy ride!

This Week in Space: Living on Lava Worlds | TWiT.TV
Think you're having a hot summer? Try living on 55 Cancri-e, a super-Earth with daytime temperatures above 4000 degrees Fahrenheit. Most of these super-Earths orbit frighteningly close to their host stars and have long since had their atmospheres scraped away, leaving them baked, parched rocks. But some, like 55 Cancri, still have dense envelopes of air. How is that possible, when the planet is 20 times closer to its star than our own planet Mercury? Dr. Laura Schaefer explains how molten lava worlds defy the odds.
