    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 this strange matter already exists inside a neutron star and has properties which changes matter I don't understand why there exists a neutron star instead of only strange stars. Wouldn't the strange matter convert regular neutron star matter into strange matter?

    If I understand correctly, though ("if" being the operative word here, as I haven't studied this in detail), strange quarks eventually decay to up quarks and W bosons. So wouldn't strangelets eventually just decay into stable hadrons over time? Or are they so "stable" that even the strange quark component is unable to decay?

    This is way too far. This is complete speculation. There is no evidence supporting any of this. It is only theoretical models that attempt to explain a few experimental results. I don't think this is the type of thing that Kurzgesagt should be presenting.
