I dabble in the type two fun that is mountaineering, and this is true. A good puffy and head coverings can make even the coldest temps totally bearable.

- bombcar 4y agoYou can get infinitely hot but only so cold. Curse you thermodynamics!
- Etheryte 4y agoI'm not entirely sure, is this practically true? I would expect there to be an upper limit to energy we can concentrate in a given volume even when cosmic scales are involved.
- bombcar 4y agoI believe there is a technical physical limit but it’s insanely high (which is why “temperature in the center of the sun/nuclear blast” doesn’t really work). There’s no theoretical limit, no absolute hot to go with absolute zero.
- Vecr 4y agoWell, heat is caused by particles moving around, and they can only go the speed of light max, so there is a limit. It's still extremely hot though, anything physical would be blown apart by the surrounding near light speed particles in an imperceptibly short time.
- tialaramex 4y agoAlthough temperature can be analogised to particles moving around I believe that at the extremes the fact that's just an analogy causes problems which would be relevant here.
- Vecr 4y agoWhat do you mean by "analogised"? That's literally what's happening, at least in a classical sense, right? Brownian noise, etc? I suppose it's not quite that on a quantum level though, it's closer to nuclear physics.
- tialaramex 4y agoExactly, the problem is that at extremes "classical" physics doesn't explain what we can observe.
