Distant Quasars Help Set Limits On Space-Time Quantum Foam

New x-ray and gamma-ray observations of distant quasars are being used to help scientists set limits on the quantum nature of space-time on extremely tiny scales. A team of scientists has used X-ray and gamma-ray observations of some of the most distant objects in the Universe to better understand the nature of space and time. […]
