I has been interesting to read the response to electric gravity in this forum. Seems that some good points are being made here. As the discussion has introduced the standard model of gravitation, string theory, higgs bosons and all the other ideas relating to a theory of everything that try to unify gravity with Maxwells equations. As a physicist (and an EU supporter) I have always had an interest in this.
A problem that a conventional physicist has with the EU (and particularly the thunderbolts site) is that there are too many bits that have to be relearned before you get a sense of what it is about, many way out ideas (some clearly wrong, others just not fully formed and some good ideas that need further development - works in progress). For this reason its hard to accept the EU's statements. But OK, keep an open mind and you may learn things that deepen your understanding of physics and the universe, along with having a laugh at crazy ideas.
On the theory of everything I think the best explanation is given by Hotson who discusses Dirac's equation. The link http://www.scienceforums.com/topic/2168 ... ve-energy/
has links to hotson's original papers and critiques discussing pro's and con's. Personally I find his work very compelling. In it gravity is caused by unlinked epos (electron-positron pairs) in the universal BEC (Bose-Einstein condensate). I have found this work to be easy to follow and for the layperson has very little maths. Even so, he explains a large number of things (eg origin of strong nuclear force, weak nuclear force, how the Pauli exclusion principle works, etc.). Really worth a read.
First turn your distrust of and read what is said to get the whole picture before criticising the parts. Then by all means go through and find the things to be critical of. I am sure it will get you thinking.
