The conversation between human and AI assistant.
What would happen if a gamma ray burst from a supernova hit Earth from differing distances?
What about if it came from only 50 light years away?
A gamma ray burst from a supernova 50 light years away would be catastrophic for life on Earth, with no time for preparation or mitigation. It would result in mass extinction and a possible end to life on Earth as we know it. The burst would also have significant effects on our planet's atmosphere, oceans, and geology, creating a global environmental disaster.
