Question: what is extreme temperature

Hello
That is a good question, I also asked myself that when I signed up actually!
Temperature is related to the vibration energy of particles. The more it is hot the more it vibrates and the more there is collisions between particles. Eventually when you increase the temperature you reach a point where you can break the molecules, the atoms and end up with.. fundamental particles! Once you reached there you cannot break anything more the particle. So I guess extreme temperature is the temperature when particles cannot be broken apart anymore. This happen in some particular situation like during the Big Bang, or at a collision of protons at high energy in the LHC between France and Switzerland!
