When I say "science," I am talking about hundreds of thousands of individual scientists each trying to make sense of some little, specific puzzle that personally interests them. What are you talking about?
The academic world has formed a consensus of opinion to which they have all subscribed.Yes, they have. All of the folks who spend time on this forum agree that it appears to be operated by a man named Scott. If we decide to tell our friends and neighbors who don't visit the site that this is the case, are we then each of us conspiring to oppress those neighbors of ours who think it's actually operated by a woman named Thelma?
All the people who know the most about a topic tend to agree about that topic in general. What would be your preferred alternative - every individual expert in a field thinking something completely different from any other? Your complaint at the moment is the consensus on big bang cosmology, and how plasma cosmoloy is not generally accepted. What if big bang cosmology was overturned tonight and all the experts suddenly agreed on plasma cosmology? We'd be in the same situation you find so disagreeable. So despite your charge of conspiracy because "the academic world has formed a consensus of opinion to which they have all subscribed," clearly your complaint cannot actually be with mere scientific consensus; it seems to be with the consensus on a particular theory.
Would you really expect them to stand up and risk their reputation, their careers?Do you know how a scientific career is etched into history? Think about your Einsteins, your Galileos, your Darwins. Overthrowing the worldwide consensus is precisely what a career-oriented scientist wants to do to hit it big. That alone is a fatal blow to your conception of science as a process, and it is why conspiratorial scientific oppression could never actually work (particularly in our environment of instantaneous and worldwide information access).
The proof is out there but you need to look and more importantly use your logic to question. Plasma cosmologists are questioning the BB. By their questions all the other theoretical concepts become questionable. The Higgs particle, we are told by particle physicists, came into existence at the BB. So do we then question all their theories if the BB has no value? You should start with you googling plasma cosmologists and the BB initially.Fair enough. If I really want to understand the science, it is my responsibility to self-educate.
For a basic grasp, we start with Wikipedia:
Wikipedia article on plasma cosmology wrote:Proponents of plasma cosmology claim electrodynamics is as important as gravity in explaining the structure of the universe, and speculate that it provides an alternative explanation for the evolution of galaxies[8] and the initial collapse of interstellar clouds.[19] In particular plasma cosmology is claimed to provide an alternative explanation for the flat rotation curves of spiral galaxies and to do away with the need for dark matter in galaxies and with the need for supermassive black holes in galaxy centres to power quasars and active galactic nuclei.[8][37] This is controversial, as theoretical analysis shows that "many scenarios for the generation of seed magnetic fields, which rely on the survival and sustainability of currents at early times [of the universe are disfavored]",[20] i.e. Birkeland currents of the magnitude needed (say 1018 Amps) for galaxy formation are thought to not exist.[16]Well, okay. So the there is a certain magnetic current that must exist if the plasma model is a plausible explanation, but no such current has yet been observed and theoretical analysis doesn't think they exist. Also, it seems that certain effects of a plasma model that should be observed in the universe if it's correct directly contradict current observations of our universe. As well, it seems our most advanced measurements have confirmed data that fit the big bang model while being at odds with the plasma model (among other alternatives).
Light element production without Big Bang nucleosynthesis (as required in e.g. Alfvén-Klein cosmology) has been discussed in the mainstream literature and was determined to produce excessive x-rays and gamma rays beyond that observed.[40][41] This issue has not been completely addressed by plasma cosmology proponents in their proposals.[42]
In 1995 Eric Lerner published the only proposal based on plasma cosmology to explain the cosmic microwave background radiation (CMB) since the Cosmic Background Explorer (COBE) results were announced in 1992.[43] He argues that his model can explain both the fidelity of the CMB spectrum to that of a black body and the low level of anisotropies found. The sensitivity and resolution of the measurement of the CMB anisotropies was greatly advanced by WMAP. The fact that the CMB is so isotropic, in line with the predictions of the Big Bang model, was subsequently heralded as a major confirmation of the Big Bang model to the detriment of alternatives.[44] These measurements show the acoustic peaks in the early universe are fit with high accuracy by the predictions of the Big Bang model. There has never been an attempt to explain the detailed spectrum of the anisotropies within the framework of plasma cosmology.
But that's just Wikipedia. We can't rest on it alone. So I checked a mathematical claim made by plasma modelers with its review by a working cosmologist (i.e. somebody who would be more familiar than I would with the basic facts shared by both paradigms). Oh, for anyone interested, the difference between the plasma model and the big bang model is that plasma says electromagnetic forces (where the plasma comes in) are far more powerful and important in explaining the physical phenomenon of this universe than gravity, while big bang has it the other way around. Anyway, on to the science:
plasma cosmology wrote:This behaviour derives from Ampére's Law or the Biot-Savart force law which states that currents in the same direction attract while currents in the opposite direction repel. They do so inversely in relation to the distance between them. This results in a far larger ranging force of interaction than the gravitational force between two masses. Gravitational force is only attractive and varies inversely with the square of the distance.
a cosmologist wrote:Except for one crucial omission, this statement is correct. It is true that if you calculate the attractive force between two long parallel currents, it only goes as 1/r, whereas gravity goes as 1/r2. This means that the strength of gravity drops off faster with distance than the magnetic attraction of the two currents, so even if gravity dominates, eventually you will reach a point where the strength of gravity drops below the magnetic strength. So, it seems, you really ought to be taking all this current stuff seriously.So here we have a review of a core plasma cosmology theorem, and both a mathematical and more tangible explanation of how it is mistaken. I'm no physicist, but I can certainly understand magnets and paperclips! I'll stop short of looking for technical literature - and Wikipedia alluded to only one peer-reviewed published paper - because I'm losing interest and I'm not likely to understand any of the math or physics involved anyway.
Here's the problem though. The result that the magnetic attraction between two parallel currents drops off as 1/r only applies to infinitely long parallel currents. Practically speaking, that means that the length of each current (the length of the wire carrying the current, for example) must be a substantially bigger than the distance between the two currents. In other words, for this 1/r law to be relevant in the Solar System, there would have to be some current associated with (say) the Earth, perpendicular to the plane of the Solar System, whose length is at least several times the distance between the Earth and the Sun. The Sun would likewise have to have a current that long associated with it. And that's just batty.
The mistake here is a common mistake, actually. It involves taking a legitimate result from legitimate equations, and applying it where it does not apply. This is why, in physics, you shouldn't just do algebra blindly. You should understand what you're doing. Even if you understand the vector algebra that leads to the derivation of the 1/r force law, you need to understand why you used the equations you did, and why you made the simplifying assumptions that you did, in deriving that law. And, in understanding that you need to understand the limitations on when you can apply your result.
If you (somehow) manage to have two short parallel lengths of current all going in one direction, then the strength of the force between them drops off as 1/r2, just like gravity, once the distance between the two currents is large compared to their length. But, you can't have this, as all the charge from that current has to go somewhere. So, in practice, if you have a small bit of current, you have to have a loop. The force between two loops of current drops off faster than 1/r2. In other words, even if it's significant at smallish distances, eventually it will become insignificant compared to gravity.
That's why you can trivially make an electromagnet and pick up paper clips with it, easily overcoming Earth's gravity. However, once you move that electromagnet (say) a meter away from the paperclip (unless you've really gone nuts with your current), the Earth's gravity overcomes it and you no longer pick up the paperclip.
(Also, creepily enough, the Google results for searching "plasma cosmology" turn up links to plasma cosmological sites that use language like "mainstream dogma," "a return to real science," "soulless, Godless, depressing propaganda," and "big bang charlatans." If you'll allow me a bit of caution here, this is not exactly reputable scientific communication and my hogwash alert is on notice. Please take note that the scientist here actually took the time to show clearly how the model was incorrect. He/she didn't suppress the theory, as Xris claims scientists do - he/she laid it out publically and explained where it was right and where it wasn't.)
I've done my part, then. I found a source that let me understand how the competing claims were made and how they lead (or don't) to their conclusions. Now I'll request your evidence once more, Xris. I want you to give me evidence that science is a conspiracy, and that scientists are egoistic oppressors who forcefully hide truth from us laymen for their own gain. There must be evidence that has convinced you - let me look at the same evidence with my own eyes, please.
A final note: The logic of conspiratorial thinking is flawed logic. The simple existence of an alternative theory doesn't prove the plausibility of the alternative theory, nor is the truth of a theory inversely proportional to the number of people who believe the theory.
