    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?

          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?

                                    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.

Then in the next few billion years or so the planets we have sent the cells and atom to, hopefully will develop intelligent life and then many discover each other.

He's gonna create a bunch of people who think they understand astronomy and physics when all they're getting is a summary of theoretical ideas with no proof backing any of it. I wrote a paper about the differences between applied and theoretical science and I talked about the fact that many modern "scientists" make their living by making up theories that don't really bring us any further as a species. This stuff is all interesting but I think we need to accept the fact that were not gonna leave the solar system, and most of this stuff is just cool to think about, not to pour millions of dollars into.

However its quite possible that a black hole could be formed. We have no idea what happens. That's the problem with this channel. He often says things as if they're certain, but unfortunately we just don't know.

I guess that's maybe assuming the neutron stars have the same mass but that wouldn't be true in most scenarios. the smaller neutron star would be ripped apart and slowly increase the larger stars mass while orbiting it. Then a black hole would be created and would pull the rest of the ripped matter into itself.
