Discussion Overview

The discussion revolves around the concept of "absolute hot" as presented in an infographic, exploring the implications of the Planck temperature and related ideas in physics. Participants express varying opinions on the validity of the concept and the infographic's content.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants express interest in the infographic and the concept of "absolute hot."
  • One participant argues that the notion of "absolute hot" is nonsensical, comparing it to the Planck resistance and questioning its validity.
  • Another participant raises a question about whether physics models break down at the Planck resistance, indicating uncertainty about the correlation with the Planck temperature.
  • A participant expresses unfamiliarity with the Planck resistance and suggests that if the infographic is deemed nonsensical, it should be removed.
  • Some participants note that the infographic presents a wide range of observed temperatures, highlighting certain oversights in its presentation.
  • Concerns are raised about the use of scientific notation in the infographic, particularly regarding its accessibility to a lay audience.
  • One participant points out that the "coldest place in the Universe" is located within our galaxy, which they find interesting.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the validity of the concept of "absolute hot," with multiple competing views expressed regarding its significance and the infographic's accuracy.

Contextual Notes

There are unresolved questions regarding the relationship between the Planck temperature and Planck resistance, as well as the implications of these concepts for physics models.

Just stumbled across this on my favorite site Dark Roasted Blend:

I did not know there was an 'absolute hot'.

(it's too large to post here)

Thanks Dave, interesting graphic :)

Well it may not be "absolute hot", but it sure is absolutely hot :w
 
Sadly, the notion of "absolute hot" is utter and complete nonsense. The Planck temperature is no more the highest temperature than the Planck resistance (30 ohms) is the highest (or would it be lowest?) resistance.

Is the explanation wrong as well? That our physics models break down at that point?
 
Do our physics models break down at 30 ohms?
 
I don't know. I've never heard the Planck resistance, so I can't draw a correlation with the claim about the Planck temp.

But if the infographic is nonsense I should pull it down.
 
The only nonsenical part is the "absolute hot" part. (But that's the part that was, unfortunately, featured)
 
It is interesting to see a wide range of observed temperatures in one compilation.

Some other oversights:

Scientific notation is mostly avoided, presumably out of consideration for a lay audience, but is used when referring to the age of the universe in a couple of places.

The "coldest place in the Universe" occurs within our very own galaxy! What are the odds?
