    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 had a trip on DMT one time where I was shown the equation for how all matter in the universe works. 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?"

    This all seems very speculative and i see many holes in a lot of these theories

  44. Crawlz

    Crawlz13 hours ago

    +Edp 445 that's true to a point, but we do have knowledge that is pretty settled at least at a surface level. 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.

  45. Edp 445

    Edp 44513 hours ago

    +Crawlz well to be fair everything we see is speculative.

    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???

    why wouldn't a black hole be created if 2 neutron stars collided?

  56. Edp 445

    Edp 44514 hours ago

    +Crawlz well said.

  57. Crawlz

    Crawlz15 hours ago

    +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.

  58. Edp 445

    Edp 44515 hours ago

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

  59. Crawlz

    Crawlz15 hours ago

    +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.

  60. Edp 445

    Edp 44515 hours ago

    +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.

  97. Tobias Pause

    Tobias PauseDay ago

    2 Questions. 1Why doesnt the strangematter transforms back if the gravityproblem is solved? (like leaving the Neutronstar) 2 Why is it infectios? One tiny strangematterparticle shouldn´t have the mass to effect the others. I always sayed we´re living inside an massive black hole which will be swallowed by the next one. Its pretty much the one reason why the the distances of the Universe are not increasing so much. Its hold together from the massive Blackhole which will be swallowed and united by the small ones we see today in billion of years. Its not unlikely that the Gravity rules inside an universal size Black hole change and become less present. At least that theory fits with the always refreshing circles we see elswhere in Nature. And the fact that the inside of an neutron Star is similar to the Bigbang leads in that direction too.
