Back when I was in university (1990's), we discussed the possibility of "photon shells". These would be neutron stars so dense that light would tend to form stable orbits around the star. We always thought that it was an interesting idea, and maybe some strange physics would be going on in that shell.

[@garethdean6382]

But would they be stable? Any slight deviation from a perfect path would surely tend to result in a photon escaping or falling towards the star, yes? There's only going to be one, very thing shell where such an orbit is perfectly balanced.

They exist around Black Holes though don’t they? Innermost stable orbits which equal the speed of light?

[@Grim_and_Proper]

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.

So if Iron stars are massive spheres of iron floating in space what would happen if two of them collided? Wouldn't they explode causing them to break down into baser elements? Would the collision create light and heat? I imagine physicists have considered this.

[@frozennorth3426]

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.

[@flygawnebardoflight]

For the strange matter condundrum: Wouldn't it lose stability as it leaves the star? Or is it just THAT stable? If so, should we be thankful that the escape velocity requirements from a neutron star are impossibly high?

[@frozennorth3426]

Plenty of stuff escapes neutron stars. They’re generally extremely hot, and they also shoot out all kinds of stuff due to their magnetic fields. For example, Pulsars are neutron stars. The only object with a region that has an “impossibly high” escape velocity is, by definition, a black hole.

[@Astrofrank]

No, that needs a White Dwarf with hydrogen and helium which can undergo nuclear fusion. If these elements are only at the surface, a nova might occour.

[@lazylazerrsp8781]

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.

[@MLBlue30]

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. Everything stretches out to the extremes. I doubt one atom will ever find another one let alone a star. A dark lonely nothingness seems to be the destiny of everything and the universe seems quite fine with it. It makes me sad knowing that even light itself will be a long, long forgotten myth.

[@lazylazerrsp8781]

@@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.

A thought: due to the extreme long time it might be possible Iron stars have no chance of coming to life. Given the long time until appearance all the progenitor dwarf stars might simply collide, restart fusion or directly become black holes be gaining enough mass through further collisions. And as black holes they also evaporate and ultimately become photons before ultra-slow fusion converts them to Iron.

[@jennifersaar1611]

But why would they all collide?

[@jarls5890]

...but the universe is expanding. And if it keeps expanding - the distance between two stars, neutron stars, or black holes - on this time scale - would be so extreme that they would have no chance of ever colliding. Many black holes will grow for certain - to gargantuan sizes. But at some point they would simply run out of stuff to gobble up. And then they would slowly evaporate into photons. Photons that would ultimately be stretched by the ever expanding universe until redshifted into the extreme. Only stars, and other matter (perhaps some "lucky" rogue planet) that is drifting along in the vast empty space would slowly decay and fuse into Iron - on this timescale. The ultimate fate of neutron stars is uncertain. I do not think they could form iron stars. They would certainly lose heat and go cold. But perhaps remain in as a ball of pure neutrons with a shell of stable iron surrounding it.

[@stigrabbid589]

@@jarls5890 the main issue with theories that are that far in the future is that we cannot actually predict what will happen. We cannot accurately forecast the weather beyond maybe a day or two ahead if we are lucky, let alone any astrological stuff on a scale beyond billions of years.

@@jennifersaar1611 They already do in tightly bound multi-star systems. Also black holes in orbit around each other collide as we now know. On passing each other Newtons gravity promises conservation of energy, but only if idealized. In each pass a teeny tiny amount of energy is converted into heat, for example due to tidal forces causing internal friction in the stars. See why Jupiter's moon Io has vulcanism for comparison. Then there is the even smaller loss of energy due to gravitational waves. The net result is a loss of orbital energy among all stars, i.e the distances and also each galaxy will shrink. We are not talking trillions of years, this is much longer. But could be shorter than the scale of 10-to-the-1500 years.

[@michaelkeudel8770]

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.
