    Inside neutron stars we can find the weirdest and most dangerous substance in the universe: Strange matter. What is strange matter, how dangerous is it and what can it tell us about the origin of the universe?

    I wonder if advanced interstellar civilizations would weaponize strange matter, such as modern terrestrial nations have weaponized the atom. The act of implementing such a weapon would probably lead to mutually assured destruction, just like the nuke.

    Strange quarks are unstable (extremely short half-life) so they are no risk to anyone. They exist in the core of neutron star only due to availability of extreme energy in the core of a neutron star. Once outside, they decay into down-quarks, which merge with up-quarks to form ordinary neutrons. If the neutrons don't collide and fuse with protons, they decay (15 min half life) into hydrogen atom (proton electron pair) and merge into the inter-stellar gas/dust made of the same material. Strange stars are wonderful only inside the core of stars. Once outside, all "strangeness" is gone in no time.

    I find it strange that strange particle has never been a concern even though they never die and they spew out for millions of years and have yet to hit Earth or the Sun

    No throwing it into a black hole wouldn't help because the black hole would turn into strange matter to and it would become a strange black hole, a strange hole

    if strange matter is so fascinatingly stable then why it does not convert the whole neutron star(being in the core of it) into a strange matter star while it can convert other stars into one

    hmhmhm... i dont totally agree the fact's told by this video. Cos there is articles that proves else. And on some of then discribe strangemater very similar to darkmater or antimater , so when it encounters other subtances , both , the encountered matter and strangemater disappear or turn to energy ( explode..)

    If the core of a neutron star may consist of strange matter and strange matter converts everything it comes to contact with into strange matter, would not the whole neutron star become strange matter from its core?
