Because of the Big Bang!

For photons with extremely large energy the Universe is opaque. They would annihilate with cosmic microwave background photons and produce a shower of less energetic particles before they could travel anywhere

gamma rays are the shortest wavelength of light, on the order of 10-12 meters.

planck length, the allegedly smallest unit of the universe, is 10-35 meters.

how come we don't see light down to planck wavelengths? is it a detector problem, or a limit of the universe?

The statement engages in public discourse by addressing a scientific question about the propagation of ultra-high-energy gamma rays and their interaction with cosmic microwave background photons. It provides a detailed explanation supported by peer-reviewed models, contributing to the understanding of cosmological phenomena.
