Wallace Thornhill shows his great depth of misunderstanding of cosmology. As a student Wallace was seduced by the crank Immanuel Velikovsky. This is the source of the majority of his misunderstanding regarding electric charge and gravity.
The problem with substituting electric charge for gravity is simply this:
Electric charge is vastly too powerful a force to replace gravity and there is two parts to a charge: positive and negative, these attract. but when a discharge occurs the force is spent, and then you no longer have attraction between objects. Also if two objects are both positive or both negative they repel and they do not discharge. these points would make all objects behave very differently in the 'electric universe' that Wallace believes in. This should be very obvious, as would that we could not exist in such a universe.
Telling is this Quote from Wallace:
"In an interdisciplinary science like the Electric Universe, you could say we have no peers, so peer review is not available."
—Wallace Thornhill
That is simply not the case.
