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 ^^

I have a different though about this. I think the core of neutron star is a very small singularity and maybe that's a dark matter; no light can illuminate it and it's not harmful, it bends space and time but can't interact with physical thing because of its size. This is just my hypothesis though.

Hey, I study physics in Brussels and I'm reading a few scientific articles on the subject. In particular, it's been 35 years we know strangelets are not dangerous whatsoever. Here it is, supported by all background and calculations you might want to check : "If quark matter with strangeness is bound, then energetically it can grow indefinitely by absorbing nucleons. On might at first think that quark matter would be dangerous in contact with ordinary matter, but this is not the case. [...] To balance the chemical potential difference, there will be an almost equal electrostatic potential of +50MeV at the surface of (and throughout) a nugget of quark matter, this potential will be more than adequate to repel positively charged nuclei at ordinary temperatures or at reasonably low velocities. Quark matter is in this respect no more dangerous than oxygen." Edward Witten, "Cosmic separation of phases", Physical Review D,1984 Also, I have checked your source for your "end of the world" theory - your source EXPLICITELY says the scenario is unlikely because it would mean having negatively charged strangelets. Once again I'm a bit disappointed by the way you guys transmit scientific information.

Quark should rhyme with quart, not fart. From Murray Gell-Mann "The Quark and the Jaguar": "In 1963, when I assigned the name "quark" to the fundamental constituents of the nucleon, I had the sound first, without the spelling, which could have been "kwork". Then, in one of my occasional perusals of Finnegans Wake, by James Joyce, I came across the word "quark" in the phrase "Three quarks for Muster Mark". Since "quark" (meaning, for one thing, the cry of the gull) was clearly intended to rhyme with "Mark", as well as "bark" and other such words, I had to find an excuse to pronounce it as "kwork". But the book represents the dream of a publican named Humphrey Chimpden Earwicker. Words in the text are typically drawn from several sources at once, like the "portmanteau" words in "Through the Looking-Glass". From time to time, phrases occur in the book that are partially determined by calls for drinks at the bar. I argued, therefore, that perhaps one of the multiple sources of the cry "Three quarks for Muster Mark" might be "Three quarts for Mister Mark", in which case the pronunciation "kwork" would not be totally unjustified. In any case, the number three fitted perfectly the way quarks occur in nature."

Might just be me but isn't this argument just a bit flawed. Suppose strange matter does exist as noted and that theres a lot of it. If we assume that everything that contacts strange matter wants to change to enter the stabler and stronger form of the strange matter, and there was a lot of strange matter in the beginning of the universe, why isn't everything already strange matter. Why have we no knowledge of it until now. I want to note that in the beginning, Kurzgesagt noted that there is a chance that strange mattter converts everything it contacts yet for the entire second half, this off chance suddenly turned definitive, as if it were a fact rather then a theory

It should probably be noted that this videos topic is hypothetical in every sense of the word. There has been no observational confirmation of stable stranglets, and current observations seem to favor the idea that neutron stars (or at least their surfaces) are comprised of regular, nuclear matter. Cool video, and a good treatment of a speculative and interesting theory, but you should probably make it more clear that this is more of an astrophysical curiosity than anything else right now.

I wonder what would happen if a strangelet entered a singularity, or if a gamma ray burst shot through a strange star. Does dark matter convert to strange matter over time as well as regular matter would. What if something was shot through a strange star at the speed of light? Would its matter debilitate fast enough to become strange matter. Would strange matter be affected by a black hole as other matter would since it is the most impenetrable thing in the universe ( well ... other than flex tape at least ). This video gives me a lot of questions about strange stars.
