    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?

    Except, as you said, THEORETICALLY speaking, Strange matter could convert everything else into more strange matter, BUT, no one knows.

            What a great video!! You lost me with the Kessler Syndrome video a while back but this definitely brought me back. What a great way of exploring a new branch of physics and finding something that looks entirely plausible in our universe!

              So if a strangelet hit a star what you would get is a perfectly stable perfectly stable dense indestructible star that gives of very dim light.

              So in other words and infinite (but weak) energy source.

                      I have so many questions, why would strange quarks only exist inside of neutron stars if they convert everything they touch? Wouldn't they convert the outside too? why aren't we observing stars wink out all the time if this is a real threat and they've existed since the birth of the universe? why hasn't it happened to us yet? how could we possibly know of all of these qualities of strange matter if its never been observed? how can we tell it even exists?

                                          I got an idea. You can probably talk about how Apophis will destroy the earth if it ever hits the earth.

                                                2:40 All other quarks(including strange quarks) seem to decay away quickly.

                                                4:05 Strange matter(which is made of strange quarks) is perfectly stable.

                                                Lol look at this perfect logic.

If you ask the ultimate question while going into a DMT trip you can possibly see this as well. The ultimate question is: "Why does the observer effect the outcome?"

We know how to do chemical reactions even if we don't exactly know how atoms formed. We may not know all the workings of the universe but honestly we don't need to. Understanding what's inside neutron stars is exactly crucial information.
