Moffett Field CA (SPX) May 07, 2014A rock the size of a small city hurtles towards Earth, smashing a crater bigger than the span between Washington, D.C. and New York City. The heat and shockwave raises the temperature of the atmosphere above boiling as huge seismic waves ripple through the Earth's crust. New research indicates that such an impact may have happened to our planet, although (thankfully) it was long before civ Reported by Space Daily 4 hours ago.
