Is There an Absolute Maximum Density for Substances?

[Cody Wall]

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.
