I have seen videos online about how dangerous strange matter is... which is something I have never understood since strange matter created in a lab always disappears very quickly. However I watched a video today about the continent of stability at around 300 daltons. At 315, the protons and neutrons break down into U and D quarks, making the nucleus free quarks... Supposedly any matter that touches this atom breaks down into U and D quarks and is added to the nucleus. Also supposedly this matter is stable at room temps and pressures.

I cannot find the paper online to support this.... Has anyone read this paper and if so, what are your thoughts?
