The energy generated by nuclear fusion has great potential as a clean and almost limitless source of energy, but many obstacles must be overcome before it becomes a practical reality, and scientists may have escaped from another. New models of an unwanted fusion phenomenon called ‘chirping’, where vital heat can …

When you imagine the Solar System in your head, most people think of the Sun, motionless and stationary in the center, with everything else buzzing around it. But each body in the Solar System also exerts its own gravitational pull on the star, causing it to move only slightly. Therefore, …

A 50-year theoretical process to extract energy from a spinning black hole finally has experimental verification. Using an analogue of the required components, physicists have shown that the Penrose process is indeed a plausible mechanism for extracting some of that rotational energy, if we could ever develop the means. That …
