COSMIC

System76 has announced that its COSMIC desktop projects will no longer accept LLM-generated content in code submissions. Pull requests containing code written by large language models will be rejected, with the company citing problems AI tooling has caused for developers. The move makes System76 one of the more prominent open-source developers to explicitly ban machine-generated contributions, and it is drawing attention across the Linux and free software community.

A mysterious high-energy particle that struck Earth in 2023, first detected by the Telescope Array observatory, continues to puzzle physicists because it came from empty space and defied known energy limits. A new proposed explanation, described as one of the strangest yet, is drawing attention in science reporting as researchers debate what could have produced such a powerful cosmic ray.

Physicists have outlined an explanation for how a photon with an energy of 300 teraelectronvolts — among the most energetic gamma rays ever detected — could have travelled to Earth. The finding matters because such high-energy photons should in theory be absorbed or degraded over cosmic distances, so a viable propagation mechanism challenges existing models of intergalactic magnetic fields and fundamental physics.

Space radiation can set off a biological cascade that leads to cancer, according to a new report from Universe Today. Beyond the immediate DNA damage caused by cosmic rays and high-energy particles, the radiation appears to trigger downstream processes in cells that promote tumour development over time. The findings matter for long-duration missions to the Moon and Mars, where astronauts face prolonged exposure outside Earth's protective magnetic field.

New research in physics suggests quantum interactions in the early universe may have locked cosmic fields into their existing energy states, helping explain why the universe settled into the configuration we observe today. The idea offers a possible mechanism for how fundamental fields stabilised after the Big Bang, and is drawing attention from cosmologists interested in the origins of physical constants.

A report from Futurism claims the Solar System is inherently unstable and destined for eventual destruction. According to the headline, planetary orbits will not remain orderly forever, with gravitational interactions potentially leading to chaos over vast timescales. The article presents this as the long-term fate of the Sun and its planets, a stark framing of cosmic instability that has drawn attention as an alarming take on our cosmic neighborhood.

New research using cosmic gamma rays is probing whether the speed of light is truly constant, a cornerstone of Einstein's relativity. By studying high-energy photons that travelled vast cosmic distances, physicists are searching for tiny deviations that could point to quantum gravity effects and challenge the limits of Einstein's theory.
