Citat:
"Giant hole appears at 'world's end'. Siberia’s frozen soil — known as permafrost — contains millions of tons of methane gas. As the surface slowly warms, this gas begins to be released — and pools into highly volatile pockets. A mixture of water, salt and gas may have ignited an underground explosion. Another possibility is that the gas pocket may simply have built up enough pressure to pop like a Champagne cork , though given that the earth around the eruption is burned , that seems unlikely. I'm no geologist but that's calcined rock right there.
I guess alien stories are more interesting than science but why the hell do we have to use fracking to get our natural gas, when it just explodes out of the ground there? Does that particular hole look safe to you ? Would you like to live on Venus ?
Tycker den här snubben förklarar det ganska bra!
