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?

If strangelets could've been around since the begining there must be a way for them to decay back to regular matter otherwise a big chunk of the universe would already be strange matter.

So if a strangelet hit a star what you would get is a perfectly stable perfectly stable dense indestructible star that gives of very dim light. So in other words and infinite (but weak) energy source.

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?
