    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 ^^

    How ... Biblical. And the name of the star is called Wormwood: and the third part of the waters became wormwood; and many men died of the waters, because they were made bitter. Revelations 8:11 so that's how it's going to end... How interesting my Bible predicted this before scientists.

    @Philipp Ramolla well I know it have a negative mass, which is really cool, I could use some of that myself. But as for this "exotic matter" he talked about, I am not convinced it exist, as most of the things on this sight it is highly speculative. In general I don't believe in anything I can't see or deduce from reason and dark matter, just like dark energy are simply ad-hoc variables added to our equations in order for them to make sense. Ad hoc solutions are dubious at best. A better theory would be one who can explain gravity without resorting to unobservable constructs such as dark matter. Once we get that theory we can basically throw everything we currently know about the universe out with the garbage. But for now, the all important mission is that we adhere to the principle of anthropocentrism. Humans are the only thing that matter, and every effort we make should be towards the betterment of mankind. What can we use this speculative nonsense on? Fusion power would be great, really great, but if it is not useful (for mankind) it is not important. That is a razor more important than both Occam's and Newtons flaming laser sword.

    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."
