Another Bohring article?

Problems with the Bohr model of the atom: it claims that the reason the electron does not degrade and collapse into the nucleus is because the electromagnetic force pulling the electron in is balanced by the centripetal force from the kinetic energy of the electron (moving really really fast around the core). The problem with this model is that maintaining its super fast speed is the only thing that keeps the electron from degrading into the nucleus and letting off a LOT of energy (Einstein's E=mc^2). The universe has been around for some 14 billion years, I think matter is a little more stable than that!

There has to be a force that keeps the electron in a stable orbit – a force that repels the oppositely charged nucleus and electron. I'm arguing that it is in fact the counterpart to the strong nuclear force (repelling oppositely charged particles) that is keeping the electrons in the stable orbital positions that we observe.

So the idea is that an electron stays where it is in orbit around a nucleus because the outward centripetal force plus the strong force are balanced with the electromagnetic force. The strong force is thought to be insignificant at electron orbit distances. I can't help but wonder if at least a little of the strong force is still there and that this amount is just enough to keep the electron in orbit. If the electron loses some kinetic energy and starts moving towards the nucleus, then this strong force coupled with an increased centripetal force (as the electron moves towards the nucleus its orbit becomes tighter) pushes the electron back out to where those forces are balanced with the electromagnetic force.

Also the strong force seems like a plausible explanation for the well-known MRI fat shifting effect. In MRI we image hydrogen. If it is bonded to oxygen (like in water) it rings at a certain frequency, if it is bonded to carbon it rings at a slightly different frequency. The most sensible explanation I can think of would be that the difference in the force exerted by the neighbouring oxygen and carbon atoms  accounts for creating a local change in the net electromagnetic-strong force exerted on the hydrogen proton that we are imaging, thus pushing the ringing frequency of the proton slightly. This might demonstrate the existence of a weak strong force at these molecular distances.
