$\begingroup$ It's odd that the "dangerous strangelet" keeps getting brought up on respectable sites like PBS and others. If the pressure inside a quark star is enough, if may get stranger.

These quarks can’t be broken down into smaller particles for they are considered elementary. Quark, Strangeness and Charm is the seventh studio album by the English space rock group Hawkwind, released in 1977.It spent six weeks on the UK albums chart peaking at number 30.. Some of the quarks may be converted into strange quarks. Quark star is a hypothetical type of compact object mainly made up of quark-gluon plasma.

Stars made of this are called quark stars. The collision might have enough energy to change some of Mercury's down quarks to strange quarks. It’s something that can basically occur anywhere, under any circumstances for its exceptional stability. In there core we may find the dangerous substance in existence: Strange Matter, a bizarre thing so extreme that it bends the rules of the universe, and it could infect and destroy everything it come in contact with or it could teach us about how the whole universe began, or maybe both.
Example of hadrons containing strange quarks include kaons (K), strange D mesons (Ds), Sigma baryons (Σ), and other strange … The other problem I have with the strangelet question is this: If a strangelet hits Mercury. Strange Matter is a result of exploding neutron stars, forming strange quarks. Neutron Stars are the densest thing in the universe that are not black holes . The strange quark or s quark (from its symbol, s) is the third lightest of all quarks, a type of elementary particle. It’s very stable, immensely dense and indestructible. Let's Get Strange: Quark Stars The reason why neutron stars can withstand the tremendous gravitational forces that come with being so dense is a quantum property known as degeneracy pressure.
Though from the outside, they may not look any different than your typical neutron star. This is Hawkwind's seventh studio album, hence "The Hawkwind Part 7" title on the inner sleeve. Theoretical investigations have revealed that quark stars might not only be produced from neutron stars and powerful supernovas, they could also be created in the early cosmic phase separations following the Big Bang. Strange quarks have odd nuclear properties. Quark stars made of strange quark matter are known as strange stars, and they form a subgroup under the quark star category.. ... Gordon Ramsay called it "the most dangerous cheese in the world." 11 strange cheeses and their surprising origins. They are heavier and stronger. Strange quarks are found in subatomic particles called hadrons. Strange star is a type of quark star made of strange matter.
