Cosmic Impact

"One of the greatest existential threats to life on Earth is a tremendous cosmic impact. Whether from an asteroid, comet, or even an interstellar interloper, an energetic-enough collision with Earth — typical of objects a few kilometers or larger in size — could easily cause a mass extinction event. In the worst-case scenario, it could even completely sterilize a living world, bringing an end to a multi-billion year chain of life."https://bigthink.com/starts-with-a-bang/jupiter-extinct-dinosaurs/?utm_source=substack&utm_medium=email&utm_campaign=swab
