Could asteroids bombard the Earth to cause a mass extinction in 10m years?

Scientific researchers trying to find evidence of how asteroid impacts occur at regular intervals

 

Scientists have spent decades debating whether asteroids and comets hit the Earth at regular intervals. At the same time, a few studies have found evidence that the large extinction events on Earth – such as the one that wiped out the dinosaurs 66m years ago – repeat themselves every 26m to 30m years. Given that there’s good evidence that an asteroid triggered the dinosaur extinction, it makes sense to ask whether showers of asteroids could be to blame for regular extinction events.

 

The question is extremely important – if we could
