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 strange matter can infect other stars, how our universe could be born? Should we receive the signal of energy released when a star is being infected if this theory is true?

    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.

    I normally love your videos but to be honest this hardly explained anything, why is it so stable?

    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?
