A recent breakthrough in gamma ray astronomy could revolutionize our understanding of the universe. Scientists have detected gamma rays with energies up to one trillion electronvolts, making them the brightest gamma rays ever observed. This is more than ten times higher than the highest gamma ray energies ever recorded before. These ultra-high energy gamma rays can be used to explore the extreme physics of the universe, such as the origin of cosmic rays and the structure of the universe at its largest scales. This could help us to better understand what the universe is made of and how it works.
