      Even strange matter needs a minimum of mass to be stable. Otherwise the LHC had destroyed the world so far. Secondly it is highly possible that our Solar System contains a lot of matter, who could came from Neutron star crashes.

                                      So why wouldn't the strange quarks within the neutron star spread and convert the neutron star into a quark star? Or... it always does, and the center of a black hole is indeed the quark star...
