I'm always confounded when I read these forums, there are many of them, by good faith folks who deny that electromagnetism, a fundamental force, 39 times stronger than gravity that is more dynamic, having two qualities, attraction and repulsion wouldn't have a major role in space dynamics at all structural levels.
Well, first off, you've got the talking point wrong: electromagnetism is frequently referred to as being 39 orders of magnitude stronger than gravity, not 39 times stronger. Rather major difference, and one which on its surface would seem to bolster your case, so it's a strange mistake for you to be making. But the thing is, comparisons between fundamental forces are only meaningful in relation to a particular interaction. For example, different objects have different charge-to-mass ratios, so the strength of gravitational to electric forces is going to be different as well. So where does that 39 orders of magnitude factor comes from? It comes from the comparison of the gravitational attraction of a single proton to a single electron compared to the electrical attraction of a single proton to a single electron.
But of course, when you want to talk about anything large, you're not talking about single electrons and single protons. Even ignoring neutrons (which feel gravity just as strongly as protons but don't feel electric fields at all), most of the universe is made up of fairly balanced amounts of protons and electrons. In fact, it's precisely because electricity is so strong that most of the universe is very close to charge neutral. So for example, let's consider the interaction between the earth and the moon. Now, the protons on earth will repel the protons on the moon, much more strongly than gravity. But they'll also attract the electrons on the moon much more strongly than gravity. So we need to consider the net electric force on the moon. And because the moon is very close to charge neutral, that net electric force on the moon turns out to be FAR weaker than gravity.
So to claim that electromagnetic forces are stronger than gravity is highly misleading. Sometimes they are, often they are not. And precisely because electric forces have both attractive and repulsive contributions, and precisely because more complex behavior like shielding is possible, and precisely because electron-proton electrostatic interactions are so strong, electric forces tend to cancel each other out. And the larger length scale you look at, the closer to total cancellation you tend to get. But gravity? It's
always attractive, and it can
never be shielded. So the larger length scales you look at, the more important it becomes.
The scientific evidence is there for all to see, first confirmed by in situ observation & measurement in near-space by NASA, starting in 1973 with confirmation of the electromagnetic properties of the Birkeland currents between the Sun and the Earth
Crunch the numbers sometime, see if the forces involved come anywhere close to the strength of gravitational attraction between the sun and the earth. You will find that gravity dominates the interaction, and electricity is a very minor perturbation. And interesting one, to be sure, and one responsible for some neat effects like the aurora, but still far less important than gravity. So small, in fact, that you don't even need to consider them if you want to calculate the earth's orbit.
In any normal scientfic proceeding that consistent detection of a fundamental force, electromagnetism, would be cause to conclude it is likely that beyond where Science can send in situ observation & measurement apparatus (satellites and probes), there also is electromagnetism at work.
Nobody is denying that electromagnetic forces are present throughout the universe. But large-scale structures are driven by gravity, not electromagnetism, because at large scales, gravity is far stronger. Every measurement you reference is in line with this basic fact.
Yet, it seems that "modern" astrophysicists are dragged kicking and screaming every step of the way.
Why is that?
You imagine something that simply isn't the case. That's why.
Could it just be possible, that preconceived ideas held by "modern" astrophysicists have an impact on their approach to electromagnetism.
Could it just be possible that you don't actually know what you're talking about?
