    I have so many questions, why would strange quarks only exist inside of neutron stars if they convert everything they touch? Wouldn't they convert the outside too? why aren't we observing stars wink out all the time if this is a real threat and they've existed since the birth of the universe? why hasn't it happened to us yet? how could we possibly know of all of these qualities of strange matter if its never been observed? how can we tell it even exists?
