    Is there such a thing as quark degeneracy pressure? Maybe a ball of quarks that has an escape velocity faster than light is the end result inside the inner horizon of a black hole rather than a singularity with a bunch of infinities.

                  I wonder if some of the "strange" stars like a preon stars could be mistaken for a light-weight black hole as opposed to a neutron star. I ask this for the following reasons:

                  1) The escape velocity for these stars could be greater than speed of light. . . not sure, though, since I haven't seen any info on the internet showing the theoretical escape velocity for such a star.

                  2) Even if hypothetical escape velocity for a preon star is lower than speed of light, perhaps the "superfluid" which it is made out of slows down light enough to keep it from escaping (ex: light travels slower thru water). After all, CMB light/radiation didn't appear until about 380,000 years after the big bang because the light/radiation was scattering and going no where until the density of the universe was small enough to form hydrogen atoms.

                  Comments anyone?

                        I do realise this is a really old video, but it was during this one (of the many hundred) that I've watched that truly made me realise just how small Earth truly is. Though I do actually have a question, I'd be very interested to hear your thoughts on it. (:

                        In the events you describe around 9:10, where (I presume?) a star collapses into itself, resulting in a a supernova event... You go on to say that astronomers haven't yet found the expected "Neutrino Star" at that location. But this makes me wonder about the time-based distance measures we use, aptly called light years...

                        It's safe to say that, there are forces out in the soup that our solar system is floating through, that have the ability to bend light.. This implies the ability to alter a light particle's direction, and by relation, it's speed.

                        I'm pretty sure the guys behind our society's current scientific knowledge (generally speaking) would've come up with some explanation for that.. Would you perhaps consider talking about that for a bit?

                          Oh and the forces bending light and altering our view, spacetime, gravity, whatever,has been proven in footage of a solar eclipse. Einstein was totally right in his t of gr.

                          Time-based distance, this is something I wonder about now thanks to you I have it in words. When these events happen, depending on how many light years away they're millions (or billions)of light years away, right? So how would they know what's happening in so-called "real time"? We have hundreds of satellites around the world, UV telescopes and still launching (James Webb?). It's neat because in ways this is like looking back in time, but how can we know about events happening now? Time-based distance, I like that.

                        Here is another possibility. Heaviest non-black-hole is a TBB-neutron star in which all up and down quarks have transitioned under extreme gravity into top and bottom quarks. The additional mass of 3rd generation quarks consumes nearly all energy so these cryogenic-temperature dead-stars are near-impossible to detect using electro-magnetic interactions with us. Their gravitational influence makes them appear like dark matter stars. As gravitational-wave astronomy matures over next few years, there will be several discoveries over the coming decades helping us understand which new pressure is extreme enough to prevent them from collapsing under gravity into a black hole. Interesting times ahead !!

                              Stars made from quarks are quark stars that come from neutron stars but strange stars are stars made from only strange quaks not up and down quacks as it comes fron a quak star

                                              If the pressure in the core of neutron star is so extreme. It would mean you get an extreme temperature. But if the particles are pressed together so tight that the atoms themselfs can move let alive the quarks, wouldnt that mean that it would be really cold even colder than absoulute zero. Or would the heat win over the cold.

                                              And if the heat win couldnt that contribute to a sort of resistance to becoming a black hole due to the high temperature making all the matter want to move around?sry if im unclear

Took a few courses in University, but just couldn't grasp the advanced mathematics. Funny thing is, 30 years later and I have learned enough of the math to make a small bit of sense of some of these theories (should have stuck with it). Anyway, I had heard of a Quark Star once before and it interested me, unfortunately, something else took my attention away. This is fascinating stuff, thank you so much for re-introducing me to the ideas. I know where my amateur studies will be taking me for the next little while. Quark Stars? That is just incredible.
