Heat Interactions with Non-Normal Matter

Click For Summary

Discussion Overview

The discussion revolves around the interactions of heat with various forms of non-normal matter, including dark matter, anti-matter, and strange matter. Participants explore theoretical implications and the nature of these interactions, particularly in the context of thermodynamics and energy transfer.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants propose that heat interactions with anti-matter are similar to those with normal matter.
  • Others argue that dark matter does not interact in a way that could cause heat, as it primarily interacts through gravity, making heat a non-applicable concept.
  • One participant mentions that strange matter has not been observed, complicating any claims about its heat interactions.
  • A later reply suggests that dark matter may have interacted heavily with surrounding matter in the early universe, but this interaction ceased as the universe expanded, implying a temperature at the moment of cessation.
  • There is a discussion about the potential for dark matter to interact through the weak force or other unknown forces, though this remains speculative.
  • Some participants caution against discussing hypothetical interactions without substantial evidence, emphasizing the weak nature of any potential interactions between dark matter and normal matter.

Areas of Agreement / Disagreement

Participants express differing views on the nature of heat interactions with non-normal matter, particularly regarding dark matter and strange matter. There is no consensus on the mechanisms or implications of these interactions.

Contextual Notes

Participants highlight limitations in current understanding, particularly regarding the observational status of strange matter and the speculative nature of dark matter interactions beyond gravity.

So I saw another post asking about heat interactions in a vacuum, and it got me to wondering: is there any significant interaction of heat with non-normal matter, such as dark matter, anti-matter, and strange matter. I would assume the heat interaction with anti-matter would be pretty much the same as normal matter, but I'm not sure and have no idea at all about other types of matter.

Antimatter is the same as normal matter in regards to heat. Dark matter has not been observed to interact in any way that could cause heat. It doesn't seem to interact through any force other than gravity, which would not allow it to transfer energy around to other particles, so heat isn't even a concept you could apply to it. Strange matter hasn't been observed to exist at all, unless you count dark matter as strange matter, so we can't say anything about that.

Yes. One thing that you learn in thermodynamics is a "cookbook" method for figuring out how weird new manager behaves with heat. Describing that "cookbook" method is something you'll find in Thermal Physics by Kittel and Kroemer.

The important quantity is to figure out how much energy transfer happens. Once you have significant amounts of energy transfer then things will go to a particular distribution.

Dark matter is interesting because when the universe was young then dark matter was reacting very heavily with the surround matter. As the universe expands, dark matter stops interacting, so it will have the temperature of the moment at which dark matter stopped reacting.

Couldn't it interact through the weak force, or some equally weak unknown force? It would be hard to tell.

We should avoid talking about things that COULD happen unless we have good reason to believe it SHOULD happen. Dark matter may interact with normal matter, but if it does then it does so only very weakly. I don't know if we think it may interact through the weak interaction or not.
