    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?

          Another monster is gravitational strings, black hole in shape of a line that cuts thru anything and everything.

            Quarks are hypothetical subatomic particles, which meaning, they don't exist. As such, your video is flawed. Do some better research next time.

                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.
