OK, let me ask you... Do you believe invisible explanations that go unobserved have a place in science or are in the slightest scientific at all?
That is exactly what Einstein has given us! A theory that actually *REQUIRES* us to invent things to make it work, things that to this day have never been observed, not even once. So, I fail to see the reaction and problems towards the OP.
Why do the protoplanetary disks have to be accretion disks? Why can't they be expulsion disks of matter being ejected by the star? I don't see why that is any less valid. If they are accretion disks, then where did the initial mass come from to create the star in the first place? Why does accretion stop at certain points? Why do stars form at all and not just a bunch of dead rocky/gassy worlds?
That only means we don't (completely) know how it works. But to claim that everything we know it wrong and that it works like this and that is a whole different thing. And that is what the OP is doing. While also his own hypothesis requires us to accept something that we should observe but have never observed, at a fundamental level.
Well, I am open to any hypothesis. And I will just say out loud that I don't know how it works. But whenever someone proposes a theory while claiming all we know is wrong, he will have to come with some very good foundation to support his theory. Even I, pretty much a laymen on the subject, can almost directly point out the major flaws in his hypothesis. I think most people will be happy to discuss alternative hypotheses. But not with someone for whom an unfounded hypothesis is considered the whole and absolute truth.

So, your saying it's perfectly acceptable to hang onto a theory that actually requires one to invent unobservable and unfalsifiable constructs to make it work with new observations that defy that theory?
Your right though, currently we haven't observed the actual birth of new stars and planets, so technically both hypothesis are just as valid until just such an observation is made. Currently, nothing Einstein has predicted has to my knowledge actually been observed and cases of possible observation can be more simply explained, like so called gravitational lensing.
The OP is going out of his way to provide well written posts detailing the many failings of current Einsteinina physics, with more than an adequate number of links to jump start anyone's continued research in the area. It makes no sense to state without warrant that plasma physics would hold no importance in space born plasmas. Our sun is a plasma, so we need to work with what we know about plasma's, and plasma are capable of discharging. I see no logical reason that such discharges can't be scaled up in larger plasma's such as stars.
Unfounded? Have you not noticed the start of every thread he has made? He begins each thread with current research and observations that show various aspects of Einsteinian physics being proved wrong. After which, he then provides a viable alternative theory to explain the observations and research newly discovered. What flaw is there in plasma physics? Why can't it be scaled up? What causes stars to form in the first place if plasma physics can't possibly have a role in star formation?
Science is not stagnant nor is it science when one needs, no, is required to invent unobserved and unfalsifiable constructs for the sole intent of dismissing observations that defy the theory.
Plasma physics provide a well proven viable alternative to current Einsteinian physics. We can scale down observations and see the same effects in a lab setting, something we can't do with the many required unobserved inventions of Einsteinian physics.
As long as the theory helps us understand a lot of phenomena and as long there is no alternative that does this better, yes, its perfectly acceptable. The only other alternative we have is to have no theory at all.
Part of the hypothesis is that the sun is powered externally. So we should be able to observe a huge influx of electrons to the sun. We don't observe anything like that whatsoever. Let alone huge spikes in the influx of electrons that intensify the plasma to such an extend that fission takes place. The hypothesis provides absolutely no mechanism for these issues. It is totally contradictory to what we observe.

IBEX's recent results that have taken researchers by surprise have given yet more strength to the EU model, a model that confidently predicts that the shape of the Sun’s galactic plasma environment is the hourglass, Z-pinch shape of planetary nebulae and supernovae, aligned with the local interstellar magnetic field.

That sounds counter-intuitive to me and makes little to no sense at all. I've never heard the concept of theory gets destroyed by observations so invent unobserved and unfalsifiable constructs to hold onto observationally disproved theory, as being called science.
Why does it sound counter-intuitive? It makes perfect sense to me.
Everyone can see the problems with the model of the universe. Many scientists are trying to come up with theories which can be proven to explain observations better than the current model.
When someone comes up with a theory proven to explain observations better than the current model, then we can adopt the newer, better explanation. And when a better theory than that one is found we'll go on to that one as the consensus of the scientific community.
So in comparing alternate theories to the current model, we must ask which model explains the most, and which leaves the least unexplained, that can be confirmed? That will be the criteria for adopting the new model. It's been that way for centuries and will continue to be so.

What? So...
Come up with theory
Make predictions
Observations defy predictions
Invent unobserved and unfalsifiable explanations
Spend billions wishing really hard that the invented constructs are true
That is science?
Alexis Bouvard (June 27, 1767 – June 7, 1843) was a French astronomer. He is particularly noted for his careful observations of the irregularities in the motion of Uranus and his hypothesis of the existence of an eighth planet in the solar system.

you said:

I think this has been demonstrably proven by Peratt, Alfven, Scott, Thornhill, Falthammar, etc.. etc..
Observations at Mount Stromlo Observatory near Canberra, Australia, have shed some light on 'dark matter' - the unseen material astronomers have spent decades searching for. An international conference at the Academy of Science in Canberra was told yesterday that Australian and US researchers have found objects, lying in a 'halo' around our galaxy, that could account for about 50 per cent of our galaxy's unseen mass.
The hypothetical star-sized lumps were christened MACHOs - MAssive Compact Halo Objects.
Astronomers may have underestimated the tally of galaxies in some parts of the universe by as much as 90 percent, according to a study reported on Wednesday in Nature, the weekly British science journal.
Yes you do. And when the rest of the scientific community agrees that observational evidence supports the alternate theories, they will eventually adopt them. Perhaps not those specific alternate theories, but eventually the current theories will likely be replaced by alternate theories of some sort that do a better job of explaining the observations. And it might take some time.
One of the things I like about this thread on the formation of solar systems, is that mainstream science is unsure of itself regarding the widely known problems with models of planetary formation. So I suspect mainstream scientists are particularly open to good alternate theories in this field. And I think we all agree that none of them are proven until they are proven. Neptune wasn't proven until we really found it, dark matter won't be proven until (and if) we ever find it.
So I suspect we will find more MACHOs, and I fail to see why this is different than the Neptune example. Gravity models predict something is there, you look for it, you find it, looks like we've already found some of it at least for our galaxy. There's more to find in the universe, and we've found some of that too:
Well if we've underestimated the tally of galaxies by as much as 90 percent, wouldn't that account for some of the missing dark matter? And that matter isn't even really dark, but just blocked from our view so we couldn't see it. Don't be surprised if we make more discoveries like this of MACHOs and previously unseen light matter.
One thing that is helping to advance cosmology is the development of better, more sensitive instruments. And I expect those to be particularly helpful in this field, of how solar systems develop. So let's come up with some creative theories, and see which of them are proven with the newer observations using the better, more sensitive equipment.
Given the variety of types of solar systems we are seeing, more than one of those theories may prove to be correct. But it may not be necessary to throw out Einstein to come up with these new theories.

Seriously, you honestly believe this is what's causing the variance?
If one considers an electric model of stars, the variability is easily explained without any need to invoke dark matter.
We have developed selection criteria (“cuts”) that use
the level-2 statistics to distinguish microlensing from
backgrounds such as variable stars and noise.
The data set used here consists of about 256 billion
individual photometric measurements. Discriminating
genuine microlensing from stellar variability, background,
and systematic photometry errors is hard,
and the significance of the results depends upon the
event selection criteria.
The selection criteria should accept ‘true’ microlensing
events, and reject events due to intrinsic stellar
variability and instrumental effects.

I just thought of this... I'll try and check up on the age of the stars with gas giants, but suppose these gas giants are ejected, it would stand to reason that the closer the gas giant, the younger the parent star, the further away, the older as it would have had more time to migrate to an outer orbit.
I don't personally know much about all of this, but it just popped into my head just now. I'll look into it later when I get the chance, possibly start a new thread if I find any interesting results from that idea!
as the OP suggests.
