    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?

      Yo i thought of a way how humankind could survive the cold-death of the universe. I know its just a theory but please follow me on this. So we know if humans survive long enough we can become an atleast type 2 society. If we get this far we could decompose dead stars and gas planets drive them both together and create a star artificially. I must admit i know very little about it but it could be possible. I mean we could create a dyson sphere or smthng around it and transport it via an hyperspace engine to a gas planet decompose both and see the star form it self. With decompose i mean blowing them up but with much less boom ya know? Maybe a laser of sorts or other things. Its crazy i know but it sounds great in theory. Waht do you think? Let me know ^^

    If quark matter is of sufficient density to produce strange quarks, what makes them so stable and immune to decay at such high energy levels?
    Following up from that, wouldn’t it be a leap to call them perfect matter if quark matter is the result of insufficient gravity to form a black hole and thus could potentially change into a more dense singularity?
    Also what makes strange matter so ‘contagious’ that other matter would forgo the normal process of entropy and spontaneously reach a higher energy state upon physical contact?

    So if a Strangelet would convert the sun into a Strange Star why is the Neutron Star not converted?

    Its the false vaccum thing that keeps me up at night. Strangelets are a spooky concept, but probably not a thing, or it would have wrecked us by now. But the vaccum energy of the universe is fundamental, and with a bit of math you can plot out ways of breaking it, as implausibly difficult as it would be. And thats not "weird shit eats a star", thats "nothingness eats a universe"
