Dyson swarms—theoretical arrangements of satellites orbiting a star to harness its energy—may seem like they could be eternal once constructed, but they are still at the mercy of gravity. A new ...

On March 21, 2026, Elon Musk unveiled Terafab — a colossal $20–25 billion semiconductor megafactory project jointly run by Tesla, SpaceX, and xAI — in a dramatic event streamed live from Austin, Texas ...

Red dwarfs are the most common stars in the Milky Way. They burn their nuclear fuel very slowly, allowing them to remain stable for trillions of years. This gives any advanced civilisation plenty of ...

A rendering of a potential Dyson sphere, named after Freeman A. Dyson. As proposed by the physicist and astromomer decades ago, they would collect solar energy on a solar system wide scale for highly ...

New research from Germany has investigated for the first time the idea of building a photovoltaic Dyson sphere, a theoretical megastructure that could provide vast amounts of energy for interstellar ...
