Just a few thoughts....
I had a question: "How do super giant stars form?" No easy answer came to mind, it does seem to be a question that no one gives much thought to. But, think about it for a moment, if a gas cloud is gradually contracting, then at some point it will have at it's center, a star globe of about one solar mass. Well, that being the case, and since stars light up at that point, a stellar wind will begin blowing the extra gasses away. Meaning that the accretion process should halt star formation at about one solar mass.
Then it came to me, what if, instead of a star simply accreting from a gas cloud, it accreted from a cloud containing heavier elements? The heavier elements would sink to the core and prevent the star from fusing hydrogen, until the temperature at the surface of the core became hot enough. That would mean that accretion could continue way past one solar mass, depending on how big a non hydrogen core the star had. My guess is that the process is so sensitive to interference that, even a non-hydrogen core of a few meters would be enough to delay the onset of fusion, until the star became several solar masses larger. Finally, once the fusion process did get started, the non hydrogen core would be degraded by being bombarded with protons, until it transitioned to less stable elements or gasses which the turbulence could then carry away from the core.
Well, if true, this process has other implications. One being that giant and super giant stars would be relatively rare in the early universe , since helium was the only heavy element available, Because one solar mass stars are so stable that their lives are approximately 10 billion years, it takes too a long time before they throw off enough heavy elements to form the giants the universe needs to make the heavier elements and discharge them. But wait, the universe was much denser then and gas was in such great abundance, it is possible that early stars were forming heavier elements in these gas clouds by bombarding them with radiation. Also stars would have been in such great number and so close together, the opportunity for stars to grow into larger, shorter lived stars by the simple process of combining. For this purpose I'd assume that galaxies had not yet formed because there were no black holes in existence yet. Thus, stars were free to roam to wherever gravitational attractions might take them.
Well, that got me thinking about another facet of the big bang. The early formation of matter. Normally nature follows the path of least resistance, so why should it do otherwise even way back then? I'd say that after this point of pure energy began to expand and temperatures began to descend, energy would begin to transition to matter and my guess would be that quantum particles would be the first to form. These particles would then coalesce into photons, then the photons would form electrons, then the electrons would collide and form protons and neutrons. Since it takes one more electron to form a neutron than it does to form a proton, that suggests there's a statistical calculation that can be pursued, that just might throw some additional light on the early universe matters. I've read that as much as a quarter of the gas in the early universe was helium.
It comes through to me that what we're probably looking at is that everything is made of just one thing, that takes many different forms, depending on some laws we do not yet understand.

Faster-Than-Light Travel: Are We There Yet?
Long before the Empire struck back, before the United Federation of Planets federated, Isaac Asimov created Foundation,
the epic tale of the decline and fall of the Galactic Empire. Asimov’s
Empire comprised 25 million planets, knit together by sleek spaceships
hurtling through the galaxy.
And how did these spaceships cross the vast gulf
between the stars? By jumping through hyperspace, of course, as Asimov
himself explains in Foundation:
Travel through ordinary space could proceed at no rate more rapid than that of ordinary light… and that would have meant years of travel between even the nearest of inhabited systems. Through hyper-space, that unimaginable region that was neither space nor time, matter nor energy, something nor nothing, one could traverse the length of the Galaxy in the interval between two neighboring instants of time.
What
the heck is Asimov talking about? Did he know something about a secret
theory of faster-than-light travel? Hardly. Asimov was participating in a
grand science fiction tradition: when confronted with an immovable
obstacle to your story, make something up. READ MORE

At one point, in the early expansion of the universe, the expansion did, in fact, exceed exceed the speed of light. So, like most things we learn about nature, we do have a clue as to whether or not it can be done. Obviously, the theories of how the "big bang" progressed, include a clue that the speed of light can be exceeded. Now, the hard part will be, determining just what those conditions were, that allowed hyper light speed way back then. Of course, even if we manage that, it's no guarantee that we'll be able to duplicate it. It may, very well, be dependent upon the condition of the universe at that point in time, which we have no way of duplicating. Or, it may reveal that there is a way to do it.
Of course, it's a very mind bending piece of work that's probably best left to the geniuses. Thank heavens we finally have a program afoot to find these people, who may, right now, be some kid living in abject poverty in some foreign and very backward land.

Hmmm... Just noticed something odd about the Universe etc.,
I was watching a speaker talk about religious beliefs and while he was explaining why dinosaurs didn't live 3 or 4 thousand years ago, he illustrated the time scale of earth, from formation to humans using the length of his arm. That's when it hit me. It took almost two thirds of the time, from the formation of earth until the more complex life forms (dinosaurs) appeared. With humans appearing at the last end of the last third. Isn't that about what happened with the Universe formation? It took almost 2/3 of the time from the big bang until now, for the complex materials (heavier elements) to form in sufficient quantity to produce life capable planets.
If that's some sort of probability curve, perhaps the formation of life capable planets and the emergence of intelligent life, might be more closely grouped on the timeline of the universe, than previously thought. I'm thinking Carl Sagan wise, where he speculates about how large or small the time differences might be, between human emergence and that of any alien culture. Where there might be some sort of distribution of habitable planet formation around stars, that is very closely connected to the two thirds of the time the universe has been in existence.
Obviously this is a problem of probability, where, if some theory, based on theoretical "observations" were to determine, for example, that because of the quantity of heavy elements present at given points in time, life sustaining planets could not form earlier than THIS = Xn. Then from
Xn forward the probable rate of planet formation might be deduced by other statistical observations, to arrive at a period of time, over which habitable planets could begin forming. From there we would
then theorize that nearly two thirds of the time from formation to now, would be needed for intelligent life to arrive.
Of course, this exercise if mounted, would still leave some pretty large gaps over which intelligent life might have formed on exto planets, perhaps on the order of millions to even hundreds of millions of years, but nothing like the time periods over which we had to guess about before, which would have been as large as billions of years. By reducing the possible separation of the times during which life could have appeared anywhere in the universe, we might just happen on an idea that might tell where best to look.
It's not so far fetched as one might think at first glance, after all, we did discover the "big bang" and were were not only able to locate a time for it, but times for the emergence of it's various features as well. We discovered that the speed of light was not the limit it is today, but that, it only imposed itself on the universe after it had cooled and/or expanded to certain proportions.

Just a few thoughts...
While trying to wrap my head around quantum mechanics, the fear of the strange chaotics caused me to seek refuge in the more familiar E=MC². So I began tearing it apart to see what, if anything, might be hidden in there. Very often formulas tell quite an extended story, as they always seem to contain more information than what the casual observer can see.
So I say to myself; Energy equals Mass times the speed of light squared. It hits me, why squared? That would mean that energy is two dimensional, right? So where is the other dimension? Oh, I see it now, it's contained in the "Mass Times" part of the equation. But wait, let's see: Mass is detected by weight, so that's a gravity metric function, but it also must include space, since not all masses are equally dense. Well, as Einstein told us, space is really space/time, so volume is gravitational metrics over space/time. Then, not only is gravity and space involved in figuring out how much energy a given mass contains, time somehow enters the equation as well. We don't see it, but it is there.
Well, that got me to thinking about what else might be there that we don't see and why don't we see it? So I thought about how before Einstein revealed space/time, we didn't think that time was a quantity that might have any mass. But, from my readings to date, it certainly seems that time itself is a quantity that may very well have some mass. Oh gee... That leads to a whole new branch of thinking about things.
Starting way back in the past, we learned, quite reflexively, to understand the world by attempting to explain the observations we were able to make. That, initially led to Fire, Air, Water and Earth being our first elements. Of course we were wrong, but it's an understandable mistake (and I might add, one we continue to make even today). This is because of two very obvious reasons; One is that what we are able to observe doesn't always yield quite enough information, and Two, we tend to import mistakes of the past into our future theories by the simple expedient of nomenclature, the art of naming new things using old terminology.
Take, for example Dark Matter. We all know what matter is, thus by naming Dark Mater as matter, we inadvertently import all that we know about what we usually call matter. Could it be that Dark Matter isn't really our normal matter? After all, we were only able to detect it once gravitational calculations about the universe went awry. So, needing a name for it, we simply assigned it the name of Dark Matter, probably because we were looking at it's gravitational influences. Those being the only "observable" properties we could detect.
So now my mind jumps over to particle/wave theory and I begin thinking; what if we've gotten that wrong as well? We detected the electron and thought: Oh, look at this data, we have found another of natures discrete particles. Which is what we thought, long ago, about the atom, as being the indivisible thing from which all the elements were created. But we were wrong again there, atoms, we discovered were made up of even smaller "particles" which, as you may come to guess, are probably not particles at all. But, they are being thought of as such, because of our lack of knowledge and understanding, which causes us to use common assumptions and therefore names that reflect our formerly mistaken ideas and imports all the characteristics we expect discrete particles to have.
Take that electron problem, where it acts like a wave and behaves like a particle, all depending on the methods of observation. Sort of reminds me of that saying that: "When all you have is a hammer, every problem looks like a nail". LOL. So, when you're making a radio or building a generating station, electrons look like particles, but when you're building detectors, the electrons look like waves. So I thought, what if electrons were really just "wavicles"? On the simplistic theory that, if you have only a hammer, then all problems look like nails, but if you have a screwdriver then wouldn't all problems look like screws? (On the assumption that whatever you do to one side of the equation, you must do to the other side to balance it). (Insert peals of laughter as needed). But we know that all problems are neither screws or nails.
Okay, so then I thought, hey, if these particles are actually "wavicles", things that are neither waves nor particles, but look like either, depending only on the properties one is equipped to observe at the time, then it should follow that they are waves in something, but what? Then it hit me, what if they are waves in that Dark Matter? Then Dark Matter isn't really matter at all, but... (and here I'm going to reach back into our past and resurrect an old term, which hopefully, because of it's new meaning, won't import more negative learning (which I doubt because it's fallen out of use for so long). Ether!) What if Dark Matter is really this ether? What if it is the substrate that contains all these wavicles?
Imagine a universe filled with this expanding field of Dark Matter/Ether. Then, in this ether wavicles form and that is the "matter" we see and observe. We can't "see the forest for the trees" sort of thing. We can't see the Dark Matter/Ether, because we can only interact with the waves it carries upon it's "surface". Meanwhile Dark energy appears completely inert and non-interactive, all the while it is pushing everything on it apart. While the "waves" on it's surface are all these wavicles, making up the matter we see. So it could be that Dark Matter is evaporating into Dark Energy, if so then perhaps at some point, the creation of Dark Energy would slow and gravity might then win after all. Of course, it has to be even more complex than that, as you'll probably suspect, if you have any respect for Einstein and his "Within simplicity there is infinite complexity" maxim.
Well here are a few videos that may shed some light on the subject.
