Discussion Overview

The discussion revolves around the concept of whether there is an absolute maximum density for substances, exploring theoretical limits and implications of density in various contexts, including black holes and fundamental particle interactions.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants propose that black holes represent a state of maximal density, noting that adding energy to a black hole results in growth rather than increased density.
  • Others suggest that the concept of density becomes complex with larger black holes due to the lack of a well-defined interior volume.
  • One participant raises the idea that the minimum distance between particles could influence density considerations, particularly when discussing different types of particles like atoms and electrons.
  • Another contribution mentions that below the Planck length and above the Planck density, meaningful statements about density may not be possible.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the concept of maximum density, with no consensus reached on a definitive answer.

Contextual Notes

Limitations include the dependence on definitions of density and the implications of particle interactions at quantum scales, which remain unresolved.

This is kind of a random question. Is there a point that a substance density will max out? Or in other words that it cannot be compressed any further no matter the energy you add to the system?

You could consider black holes as “objects” with the maximal density for their size. If you put in more energy they grow. Larger black holes have a lower density, although that concept is a bit tricky as they don’t have a well-defined interior volume.
 
@mfb I think we should "see" what's the minimum distance between 2 particle. I think it will also affect if we are talking about atoms or other particles (such as electrons...)
 
Below the Planck length (and above the Planck density) we can't make meaningful statements any more.
