Leading Astrophysicist Warns That Sun-Grazing Comets Could Trigger Electro-Magnetic Armageddon!
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...
