How can a gamma-ray burst potentially cause the end of the world?

A gamma-ray burst (GRB) is an incredibly powerful explosion of energy that can occur in distant galaxies. If a GRB were to happen relatively close to Earth, it has the potential to cause catastrophic damage and potentially lead to the end of the world. GRBs emit an immense amount of gamma-ray radiation, which is highly energetic and can penetrate Earth's atmosphere. This radiation can strip away the ozone layer, which protects us from harmful ultraviolet (UV) radiation. Without the ozone layer, UV radiation from the sun and other sources would flood our planet, severely damaging ecosystems, causing widespread destruction of plant and animal life, and potentially leading to a collapse of the food chain. Additionally, a nearby GRB could release an intense burst of high-energy particles that could disrupt satellites, communication systems, and power grids, plunging humanity into chaos.
