¿No crees qué caiga un meteorito? Cuando la probabilidad de que eso suceda es de las más altas.
Por otro lado lo, vos y tus compañeros que hacen esa web, no manejan teorías sino hipótesis. Si plantearas estos asuntos en forma de hipótesis serían más tragables, pero llamarlos teorías es mucho.
Es muy posible el estallido de un super volcan.
Yellowstone’s Explosive Past
There have been three extremely large explosive eruptions at Yellowstone in the past 2.1 million years. During these eruptions, the most recent of which occurred about 640,000 years ago, a layer of ash covered half of North America and chemicals and ash were blown around the planet, causing a notable decrease in temperatures worldwide.
So far, Yellowstone has had gigantic eruptions about once every 600,000 to 800,000 years. Since it's been about 640,000 years since the last one, this theoretically means there could be a catastrophic eruption at any time. While scientists say it’s extremely unlikely that a huge eruption will occur at Yellowstone in this century or even millennium, they expect that it will erupt at some point in the future.
As YVO monitors the park, they say they'd be able to detect a catastrophic eruption anywhere from weeks to years before it occurred, and would be tipped off by strong earthquake swarms, rapid ground deformation and other intense precursory activity.
