If you are someone who has wondered what it is like pulling a sled across one of the poles*, we got a little taste of that the past couple days. I think we bottomed out at -30 or so without factoring in wind chill. Everything popping. I wish I had the gear to record the physical adjusting to the cold. I believe in string theory, when things drop down to extreme colds, like -273, they turn into wave patterns. The physical actually changes into new and different activity. Another dimension? Someone with more science knowledge can correct me here.
*I used to snowshoe backpack in the winter in the UP. I'm one of those people who likes cold and the cold extreme explorers. And how people live in frigid cold is fascinating.
