I have been reading this tread for a while. No, I understand just pieces here and there. Darn to theoretical for me. However, I am interested (no, not enough to be educated:) and once I got a degree in electronics, so I like when things can be explained by electrical and magnetic fields. At least it makes some sense. I have been hearing about the 'electrical universe' since long time. Hannes Alfven was a Swedish scientist and an entertaining person and this 'gravity' is so not intuitive to me. I am impressed by all the knowledge you guys are exposing. I assume you will say that my question is too simple to even address but I would appreciate just a few argument as a response. If the explanation was the 'electrical universe' then we need no quantum mechanics, no g-constant (9.81m/s2), no black holes, no expanding universe etc.Actually not even dark matter or dark energy. I am sure I am hoping for that there is a simple solution, when there is none. Just let me hear a few good simple reasons why I should just forget about that idea.
