    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?

        instead of strange matter, imagine if the core of Neutron Star is filled by Anti-Matter.

                          shouldn't neutron stars turn into hydrogen-burning stars from the decay of neutrons unbound to anything, therefore creating hydrogen, because the neutrons aren't bound to anything it has no atom to create without any protons and the neutrons that don't decay that fast fuse to make hydrogen 2 until slowly they fuse together more and more. I don't know because thinking about it the hydrogen may instantly create another neutron, but that would violate the laws of thermodynamics because it would create a neutrino which does have mass every time it decays, or maybe it just loses some charge; but a quark can not lose it's charge unless a proton or positron is shot out and for that you need at least 1 solid charge, not 1/3 or 2/3, so it then creates a paradox of infinite mass until the protons even decay, or it cools down to 0 degrees kelvin. I don't know, I may be missing something and protons aren't proven to decay quite yet but I see it as quite plausible.

                              I thought it was strange quarks make up the dark matter of the universe and since they are weekly interactive neutron stars can pull them into the core, and the star gets powered for a couple more cosmological decades from the annihilation of the strange matter

                                                                                        The properties that you say that strange matter most likely has match the theoretical properties of a singularity. Infinite density? Indestructibility?

                                                                                        Also, we know due to the laws of physics that if there was strange matter at the core of neutron stars, then the whole star would instantly be converted to strange matter, so we can already conclude that strange matter is not at the core of a neutron star.

                                                                                        We also know that neutron stars are not black holes due to the electromagnetic forces that cause molecules to repel each other, which further supports the conclusion that strange matter is not at the core of neutron stars.

                                                                                        Furthermore, if my theory that singularities are the only place in the universe where strange matter exists and is stable is taken into account, it would explain the lack of planets collapsing due to your theorised "strangelets".

                                                                                        So, for those looking for a reason not to fear strangelets, or those who didn't read the full comment :

                                                                                        Stranglets most likely don't exist, as the only place where strange matter can exist stably is under the infinite gravitational pressure of a black hole.

                                                                                        • Lünkel

                                                                                          2. A neutron star is not stabilized by electromagnetic forces between molecules. There aren't even any molecules there and the main thing keeping it from collapse is the pauli exclusion principle.
