Story summary

Scientists from the European Organization for Nuclear Research (CERN) and the University of Oxford observed stable electron-positron beams in Geneva, indicating that plasma beam instabilities do not explain missing low-energy gamma rays.
They created tiny plasma 'fireballs' to study missing gamma rays and hidden magnetic fields linked to blazars.
The results support a relic intergalactic magnetic field and may guide future research with observatories like the Cherenkov Telescope Array.
