    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?

    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?

    Just a wild theory but... Perhaps we don't see this strange matter, and haven't been contaminated with it, because it decays much faster than it can infect other forms of matter... Which would be even more strange, because apparently strange matter only decays through weak force.

    I beleive that the univers has existed forever but goes through cycles every time strange matter converts the whole universe, once all matter is converted and condensed to one massive strange star there will be a big bang that makes caos and unbalance back to the universe.

    I don't know if this true or not, but I always thought that when a star explodes, it would help continue expanding the universe. So I always thought the universe would continue expanding for a long time as long as stars explode. This made me to also believe that it is very possible for the universe to be way larger than what we initially believe considering it would expand from ripples. Much like how when you throw a stone a ripple continues on for a while. So a star exploding would expand the universe multiple times. That was always my thought. I don't know if that is true though. Haha

    If strange matter could convert any other matter into itself, wouldn't it convert completely the neutron star that contains it first? And we should have found many strange stars already, considering strangelets could convert many other stars as well.

    When you said that it takes you 1200 hours to make a video. I did the math and if you work without sleeping it would take you 50 days. But with sleep it would take you 100 days if you work 12 hours a day. So I think you lied. No offense.
