Gravity and Magnetism... One and the same?

Question

I asked this in another question as if it was an answer so as to use a bit of that questions popularity and possibly get some clarifications on this but I also prefer to make a question of my own, so here goes a copy, in case you haven't read it...

What if... gravity and magnetism are actually one and the same? I'm just pondering here basing on an assumption and a few observations, so please, bear with me...

Actually this idea of mine started after watching a video of "Veritassium" and another one of "Minute Physics"(https://www.youtube.com/watch?v=hFAOXdXZ5TM they are linked to each other at the end of the video) on youtube explaining about magnets and then it kept on developing on it's own in my mind...

When they started talking about magnets in the atomic level, talking about protons, eletrons and neutrons, how magnetism works differently on the micro-scale to our scale, and remembering another video (which I don't actually remember who recorded it or which youtube channel) that talked about ferromagnetic, diamagnetic and paramagnetic objects and a frog that they made levitate with a strong enough magnetic field, that got me thinking...

If electrons and protons have their own magnetic field and everything is made of electrons, protons and neutrons, and everything in our scale(size) and the macro-scale(planets, stars, etc) is made out of atoms... wouldn't magnetism also work differently in the macro-scale? Also, couldn't gravity be the accumulated magnetic force of all that? And magnets in our scale, could they actually be way stronger on a non-gravitational environment like space, as in, actually being "weaker" here on earth? I know there are ferromagnetic, diamagnetic and paramagnetic matter and that should cause alteration when talking about gravity or mass if it were the case but, wouldn't such a MASSIVE magnetic force, or even magnetic wave as the core and the planet or star is also spinning REALLY fast, beat that? also, after seeing this video yesterday: https://www.youtube.com/watch?v=LyvfDzRLsiU

That got me thinking about the planets and moons locked around a star or planet and why they don't simply "fall" towards each other... and a black whole would be a really tiny accumulated volume of super dense matter, right? Spinning at an ASTOUNDING speed which would make it's magnetic field... stronger? Like, SUPER strong...

Is that possible? I don't actually have a degree in anything but I have a 145 IQ and always had ease of learning and good observational skills when it comes to physics, so, it sounded pretty good to me... I've been thinking of ways to try and see if that is a reality or just a figment of my imagination, but sounds pretty logical and solid...

Hope someone here is able to test it or give me some clarifications concerning it.

And if you do test it and end up make a breakthrough, at least quote my name or this message... would make it a bit easier for me to find a job as I'm unemployed for about a year, now ç.ç I don't care much about money or fame, but not having any of them makes life quite hard on you ç.ç ahushauhsuaha

Answer 1

No, gravity can not be explained by linking it to electromagnetism. One technical reason for this is that the source of the electromagnetic field is a vector, the current density 4-vector $J^\mu$. On the other hand, the source of gravity is mass-energy, which can not be described by a mere vector and must be included in a tensor of rank 2.

Answer 2

In addition to the two great answers above, I would like to state that the E/M kinematics depends on the internal properties of the probe (specifically, on the charge/mass ratio), whether the kinematics of gravity does not. This is the fundamental difference between the two, known as the principle of equivalence.

However, most people (including me) believe that there should be a single consistent theory of everything which describes all known forces as different aspects of a single force. But not the way you suggested :)

Answer 3

By separating magnetism from electromagnetism and then by saying that magnetism produces electricity you contradict yourself. Also there is simple statement which forbid the statement from the head of your question: magnetic field doesn't have sources ($(\nabla \cdot \mathbf B ) = 0$) while gravitational field has them.

If you don't understand how 4-vector nature of electromagnetism and 4-tensor nature of gravity differ "on practice", there is article about gravitoelectromagnetism, in which there is section "Scaling of fields". So you will see how (even in linear limit) tensor nature of gravity affects the observed effects.
