So, how did this hypothetical large electrostatic potential difference influence the orbital mechanics of the probe? How did they possibly guide it there given the far stronger strength of electromagnetism, using plain old gravity and inertia? Spacecraft guidance requires precision down to many decimal places.
That's true, they will take whatever scientific facts are obtained and claim those facts support their ideas, even if they don't. Here's an example where that happened on a previous comet mission, where the probe found little surface water but it found water below the surface. The EU folks made a video which paraphrased said "see, just as we predicted there was no water", which is a gross distortion of the scientific findings. Here is my post explaining that discrepancy in the relevant thread:

Could this be the end for them? I doubt it. They'll be back soon, with a new set of rationalizations.
Religious belief takes more than facts to kill it.
Are you suggesting that EM forces attracted the probe, repelled the probe, or somehow both?
Now once the probe got close to, and actually contacted the surface of the comet, electromagnetic forces became more of a factor. At that point, it is possible that the EM forces overcame gravitational forces and may have been instrumental in causing some of the anomalous behavior experienced by Philae at touchdown.
No charge? Did you not see the articles about the comet singing from a supposed electric charge that was not expected? Yeah maybe you should check your facts a little more.
Are you suggesting that EM forces attracted the probe, repelled the probe, or somehow both?
We know that a magnetic field is present on Comet 67P/Churyumov-Gerasimenko. The currently popular meme of the singing comet is a testament to that.
It's highly likely that Philae had either an excess of electrons or protons
The gravitational forces are relatively constant along the path of the lander from release to touchdown.
Bouncing would imply a repulsion force.
The mutual EM repulsion force eventually becomes non-trivial with respect to the gravitational attraction of the objects.
There is also the phenomena of charge exchange between 67P and Philae. There will be some charge difference between the two objects.
As the objects approach one another, they attempt to come to a common energy state by "exchanging" particles, using the plasma's conductance as the medium.
Where Does Gravity Come From?
To be honest, we’re not entirely sure.

It' so funny to see people bashing eu theory while in the same time they don't know where the gravity comes from... let me quote universe today:

Where Does Gravity Come From?
To be honest, we’re not entirely sure.
and yet you are basing your outdated cosmology on your non-knowledge and acting like spanish inquisition on anyone that is open to new ideas...
hilarious
Our understanding of gravity breaks down at both the very small and the very big: at the level of atoms and molecules, gravity just stops working. And we can’t describe the insides of black holes and the moment of the Big Bang without the math completely falling apart.
The problem is that our understanding of both particle physics and the geometry of gravity is incomplete.
“Having gone from basically philosophical understandings of why things fall to mathematical descriptions of how things accelerate down inclines from Galileo, to Kepler’s equations describing planetary motion to Newton’s formulation of the Laws of Physics, to Einstein’s formulations of relativity, we’ve been building and building a more comprehensive view of gravity.
But we’re still not complete,” said Dr. Pamela Gay. “We know that there still needs to be some way to unite quantum mechanics and gravity and actually be able to write down equations that describe the centers of black holes and the earliest moments of the Universe. But we’re not there yet.”
And so, the mystery remains … for now.

Now do you reallly think the probes amazing journey was calced out and made possible by applying James Clerk Maxwell's Treatise on Electricity and Magnetism or Isaac Newtons celestial mechanics based on.... Gravity!
the physicists at CERN confirmed the discovery of the Higgs Bosun
The probe had an autonomous star tracker, it knew where it was, and made adjustments as needed.

Gravity may be an electromagnetic force
I denied the existence of gravity?
Comprehension problems, have we?
can you explain gravity to me?
I didn't know the EU people were expecting sparks. I do know the standard group were expecting snow and ice. And yet....
