Discussion Overview

The discussion revolves around the concept of maximum temperature in physics, exploring its relationship with particle velocity, energy, and the implications of special relativity and quantum mechanics. Participants are examining theoretical limits and historical contexts, particularly in relation to the Big Bang.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant suggests that the maximum temperature is linked to the average kinetic energy of particles moving at the speed of light, but acknowledges a lack of understanding regarding the quantum mechanics involved.
  • Another participant argues that special relativity alone is sufficient to understand temperature, stating that while particle velocity is limited, energy is not, allowing for potentially infinite energy and thus no maximum temperature.
  • A third participant reinforces the idea that energy can always be added to a particle, implying that there is no upper limit to temperature based on energy considerations.
  • A different viewpoint is presented, proposing that the maximum temperature could be associated with the conditions at the moment of the Big Bang, suggesting that energy concentration at that time might represent a limit.

Areas of Agreement / Disagreement

Participants express differing views on whether quantum mechanics is necessary to discuss maximum temperature, with some asserting that special relativity suffices. There is also a disagreement regarding the existence of a maximum temperature, with some proposing historical contexts like the Big Bang as potential limits.

Contextual Notes

The discussion includes assumptions about the relationship between energy, temperature, and particle velocity, as well as the implications of relativistic effects on mass and energy. The connection between quantum mechanics and temperature is not fully resolved.

so my physics teacher once told me that no one has calculated the maximum temperature reachable. I thought if particles are moving in the speed of light, since the speed of light is the maximum speed reachable, then the average kinetic energy of particle is the maximum temperature. He replied that it involves quantum mechanics and blahblahblah but I didn't really understand it. Can anybody explain to me why?

You don't need quantum mechanics for that. Special Relativity is sufficient.
Temperature is related to average energy of particles, and particle energy is not limited. Only its velocity is limited, but as the particle velocity goes close to c its mass rises, allowing to reach any energy you like.
 
You can always add energy to something, no matter how close it gets to the speed of light. There is no maximum that it can be at, so in that view of temperature there is no max.
 
Would not he maximun temperature be that that at the moment of the Big Bang?
I cannot see energy becoming more "concentrated" than at that time.
