    If stange matter transforms all matter it comes in contact with into strange matter and is very common in the universe, wouldn't it have turned the whole universe into strange matter already? Given how long the universe exists and the fact that strange matter would grow exponentially.

    if strange matter turns regular matter into strange matter, wouldn't that apply to the outer layers of a neutron star too? so if there's strange matter in a neutron star, sooner or later the whole neutron star would be strange matter.

    Why do you assume that strange matter is so very stable, when everything we made and looked at that is vaguely similar should and did decay very fast? You even say everything but up and down quarks are unstable. Sure in a neutron star, strange things may happen, but as soon as pressure is released, what tells us that that strange matter doesn't just decay?
