For those living in fear of strangelets turning the earth into a broiling blob, you probably shouldn't. Observation suggests models with stable strange matter are probably incorrect. The two biggest being: - No detections of temporarily stable strange matter in particle accelerators (as predicted by strange matter forming models); and - Nearly all neutron stars should become strange stars and this doesn't align with current observations. This is of course still up for academic debate but the existence of strange stars is looking unlikely at this point. If you want to melt your mind thinking about even longer timescales: assuming protons do not decay, iron stars are expected to become neutron stars (then black holes/ evaporation "shortly" after) between 10^10^26 to 10^10^76 years in the future. Compare that range to the unimaginably long time it took for the iron stars to form (as stated in the video) being 10^1500 years, on the order of just 10^10^3 years.

Gray Holes aren't likely to exist, or at least for long: because they'd gather more matter and thus surpass their Schwarzchild Radius. Millisecond Pulsars (everything I read says they probably aren't pulsars but something different) are interesting and have potential of being quark stars. Ultra-Cool Brown Dwarfs are interesting 'stars', or better described "Failed Stars". While most are akin to objects like Jupiter just dozens of times bigger: some appear to have solid surfaces and temperatures under 200c

12:30 And if you wanted to see an iron star die, you'd have to wait much, _much_ longer. Theoretically they then collapse into neutron stars, but that happens on the order of 10^(10^76) years.

they can’t explode. the reason all fusion eventually settles to iron is that fusing iron consumes more energy than it produces, so Iron can’t fuel fusion. thus, based purely on their combined mass, the two iron marbles would either a. become a bigger lump of iron b. be heavy enough to collapse into a neutron star c. he heavy enough to collapse into a black hole

I was just starting to write a book series based on the idea that what of the laws of physics were time/space relativistic? As in our "current instantiation of space/time" would only apply to a specific space region, other solar systems and galaxies within the Universe could actually function with different base laws of physics. Start thinking what it would be like to find out that gravity isn't directly linked to mass, or if the strong and weak forces were slightly different and allowed a bunch of different elements to form. Alternate realities, with crazy "Borderlands" interactions of two different instantiations of space time. Imagine if Earth only currently exists because we happen to be sitting smack dab in the middle of a "stable" solar system, that isn't actually stable. What would happen if two solar systems that operated under just slightly different laws of physics, "crashed" into one another. Maybe one solar mass has a strange gravity pulse that causes the other solar mass to "surf" the gravity wave, and have just the outer planets of each star slamming into each other.

Years of astronomical curiosity, plenty of Wikipedia deep dives and hours of reading, and it wasn’t until Veritasium’s black hole video that I learned that. It’s so obvious now, looking at the word, but from an English readers perspective, I can see how it’s so widespread.

With the hypothesis of such MASSIVE stars....and the James Webb space telescope presenting lights during the dark age of the universe.....how do we know that those discoveries are galaxies, and not just massive quasi-stars?

By the time iron stars form wouldn't they start colliding with eachother? That'd probably create heat and prolong the inevitable for quite a while. I'd imagine all the super iron stars would actually reverse directions via attraction to the closest mass which is most likely other super iron stars, whilst actively fighting the expansion of the universe. But since the expansion accelerates would these stars have to eventually approach the speed of light to have any hope to find eachother? Wow even as a hypothetical this seems to have lots of room for wacky physics. For some reason my mind just imagines a point in which every object in the universe will suddenly collide due to everything travelling lightspeed, thus creating a new center of the universe from which the collision of all that mass might have enough energy to create a huge explosion almost like...a big bang.

Light speed is hopelessly slow though and would take infinite mass just to reach that speed. If it takes an eternity to make these iron stars, it would take eternity to reach another one.

@@MLBlue30 the timescale I'm working with for the stars to reach lightspeed, or the universal speed limit, shouldn't be infinite. The acceleration of gravity is constantly increasing velocity which even means that if it was one atom's width per second then it'll still eventually reach it in a finite time. I'll be honest and say that the video on the shape of space being 4d is the backbone of the imagery I'm basing the wonky physics on. Just travelling at lightspeed implies you have infinite speed since time ceases to be an obstacle, but the curvature of spacetime makes everything cap at C in relation to everything else. But if everything else is also travelling lightspeed then I'm imagining the shape of reality would collapse on itself when everything is on a collision path with an instantaneous timeframe. I got lost in all the mind bending i did and really don't want to check it, so hopefully I conveyed the thought process for how it ends with a universal reset.

what he says at the end doesn't make sense: the complete evaporation of black holes CAN NOT happen before Iron starts, because an iron star has entropy still, so it can not be the end of the universe, if protons can not decay, then NOTHING can ultimately decay so no end to anything in the universe,.... it's a contradiction

Well, except that Keith Richards will still be around when iron stars form, which is something to consider when thinking about them.

Out of chaos comes order, then there must be order in chaos, then out of order comes chaos and so on and so on.

Reasons why I compare black holes to toilets: Nothing can escape the suction, but shit leaves it. The converted energy just doesn't escape as the delightful cheeseburger you plopped into the event horizon. There has been some severe digestion. (Oh, and seems to spin. Why things spin is still a mystery.)

As soon as a star starts creating iron, it only has seconds to live because iron creates zero fusion energy. At that point gravity takes over and the star collapses onto the iron core, the rebound off the core into the onrushing material heading for the core causes a Supernova. Depending on the mass of the star you either end up with a neutron star or a black hole.

strange quarks aren't "highly unstable", they last like 100 picoseconds and decay via the weak interaction. Originally, it was believe they should decay strongly, in which case their lifetime would be around 0.00000000001 picoseconds...now _that_ would be highly unstable.
