Large sun-grazing comets could bring on the sort of global electronics meltdown usually associated with electromagnetic pulse weapons or a full-scale nuclear exchange. Or so says David Eichler, lead author of a forthcoming Astrophysical Journal Letters paper positing that a sun-grazing comet roughly the size of Hale-Bopp (with a nucleus some 30 kms in diameter), could trigger cosmic ray-generating shockwaves large enough to initiate a global electromagnetic Armageddon. Traveling at a 1000 kms per second, the shockwaves would reach earth in about a day and a half. And the effects would likely be much worse than the 1859 Carrington Event, a solar superstorm that wreaked havoc on telegraph lines and caused the aurora borealis to be visible as far south as Texas...

I think a comet xcould cause a large 1859-like solar flare, but nothing much larger than that. Also such an event would be bad but not a total disaster. Many countries would have their transformers blown out and also many laptops, but in the end we will continue living. |

Well unless power grids become down for more than afew days, then we might have a Fukushima-similar scenario... |
