    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?

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.

    why do we not send a bunch of living cells and atoms out in space and to the other "Earth like planets" in our solar system so there can develop life in space? 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. And if we did this, would that be a way of colonising the rest of the galaxy???

    +Crawlz well said.

  114. Crawlz

    CrawlzIl y a jour

    +Edp 445 yeah he says at the very end "or maybe not. It's hypothetical." But he really should stress it more. 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.

  115. Edp 445

    Edp 445Il y a jour

    +Crawlz you're exactly right. He doesn't really put any disclaimer that these are all theorized scenarios.

  116. Crawlz

    CrawlzIl y a jour

    +Edp 445 the issue is collisions aren't very efficient so it's hard to believe that the mass would efficiently be compressed to singularity. 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.

  117. Edp 445

    Edp 445Il y a jour

    +Crawlz hmm... 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.
