Consider wren's statement about the speed of heat from a distant volcanic eruption: https://www.youtube.com/watch?v=4Skc3YjeTFU&t=662s
>It's insane how fast heat travels-- A big explosion off in the distance-- you would feel the heat from that on your face instantly, it's radiation.
Is he right? The statement "feels" incorrect to me, but I'm not sure. Wren has a degree in physics, but he's previously said other stupid things like "atoms are mostly empty space"
My reasoning for why he's wrong is that the radiation would be thermal, right? So the transfer of volcanic heat through the atmosphere is then by the jiggling of atoms, and I think this must happen subsonically, since the atmosphere would remain heated, unlike sound.
But what about a nuke? A nuclear explosion can emit x-radiation and gamma radiation-- would you feel heated by those? Could a volcanic explosion emit these forms of radiation?
