The threat of our existence being destroyed by a meteor, or a comet, is real, and not just a high grossing storyline from Hollywood. In fact, just in October 2016, a large asteroid came into the vicinity of earth, but thanks to a new NASA computer program called Scout, scientists detected that it wouldn’t hit the earth – this time. But these scientists however are now gravely concerned that the odds are becoming more and more stacked against us, that indeed we are actually due another extinction level impact from a space rock.
Dr Joseph Nuth, a researcher at NASA, recently expressed these fears at an annual meeting for the American Geophysical Union. He claimed that extinction level events occur every 50-60 million years, and this means our time is running out for another one. Earth occasionally does experience smaller space rocks that manage to reach and hit the surface, though many simply burn up when they hit the earths atmosphere.
Whilst the technology to detect these threats has improved, no response plan actually exists. Of all the space-rocks, the threat of a comet is the most unpredictable and menacing, as they can be randomly thrown off course and be knocked into a path heading for earth. Their speed of impact surpasses the speed of other space-rocks. In fact, Earth has had a couple of near misses
