As close as you will ever be to a nuclear explosion

THIS IS FUCKING TERRIFYING

No thank you.

The columns of smoke in the foreground are telephone poles boiling

Science side of Tumblr would like to add:

Heat is generally transmitted in 3 forms: conduction, convection, radiation.

The fact that the telephone poles and wires are boiling away well before the shockwave hits them indicates that the heat from the explosion has not reached them by convection (much slower than the speed of sound) or by conduction (at best, comparable to the speed of sound), but purely by radiation. In other words: the explosion is bright enough to boil everything.
