Oldershaw" writes: "The picture presented consists of positively charged astronomical systems embedded in an intergalactic sea of negative charge. It provides a theoretical basis for Blackett's hypothesis, although the magnetic fields are much weaker than Blackett anticipated. We find the picture of an electrically polarized universe intriguing, and yet, rather surprisingly, we have so far failed to discover any physically significant effects of immediate consequence." Note the "so far". It will be interesting to see if the solution to the dark matter puzzle will require us to reasses the authors conclusion. The history of science if full of ideas which went nowhere. If you are worried about "so far", search the literature. If nothing has come of this, there is probably a reason. If you think this is relevant to anything else, say so and why. See http://www.lpi.usra.edu/meetings/lpsc2004/pdf/1119.pdf Salt particles in zero gravity tend to spontaneusly make clumps that are somehow electrostatically defined. Static electricity could have an important role in planet formation and maybe star formation. van der waals forces not static electricity to get attraction you need opposite charges, not likely in this situatiom |

Dipoles can pair with their dipoles attracting other similar molecules, so I do notunderstand the difference being made here. Van der waals forces ARE electrostatic... to get attraction you need opposite charges, not likely in this situatiom If you have dipolar molecules yes, you have opposite charges. If you have charge accumulation by mechanical input it is the same. |
