Electronic Eng. and IT analyst, with interests in physics, astronomy, IT. A self-similar model of the Universe unveils the nature of dark energy I recomend the reading of the online book, written by my friend Alfredo Gouveia de Oliveira http://outrafisica.blogs.sapo.pt

With help of a dialog between 4 characters, and using only standard physics, the author presents an alternative view of the History of the Universe.

In order to be fully appreciated it should be read in chronological order (I'm used to google chrome browser and google reader).

Another reading that I share here is the book of Douglas Pinnow 'Our Resonant Universe'. It is a monography of a model of particles, based only on EM, that has only one parameter ('me'-electron mass) and derives the particle properties to within 1% of their values (barion masses well bellow 1%) and does not suffer of the barionic 'spin crisis'.

papers of my friend Alfredo in the arxiv:

None of these suggested readings has been comented or criticized until now.

@BMS non-uniformity reported in what observations? I forgot to add isodense ;) as observed.

comment How would charge distribute if electrons were balls?
The answer can explore that in the conductor there are free electrons, even if not charged, and all conductors have defects with potentials different from the mean where... I remember a game of N seat chairs and N+1 persons. Up N, move around N+1, seat N, and repeat...without leaving the game. Randomly 1 will be up. Which one is not relevant because the game is endless.

comment What are the current experimental limits on the polarizability of the vacuum?
lots of documents on PV at [calphysics] (calphysics.org/sci_articles.html) (I have a lot of links on PV but I dont have the time to search what is exp or theory), sorry

comment Speed of light travel
@dmckee possibly it is a question of language, or perspective: In the lab we can send a short pulsed light beam (an object it is), and then split it in two (a decision). If the IOR is the same on both paths then it is impossible to rejoin them. You can time the all operation. I suspect that you know that I know that light is always making a hard decision: What is the shortest path? Take it easy tricky light. 'proper time...is zero..' can imply that proper time is not ontological. I will have to think at GR speed: 43/5571=2*pi*369.2/300000 (in km/s). ;) I feel lucky today starting sexygenary ;)

comment Dimensional analysis and the interpretation of measures
I think that it is better to Post another question in such a way that the title is more clear, although imo the 'interpretation of measures' was at the point.

comment Dimensional analysis and the interpretation of measures
I'm asking for a reference able to show that I'm in error. It shouldnt be difficult because almost everybody beleives that I'm wrong. I use plain old mainstream arguments to show my viewpoint and expect that you, or anyone else, can show that I'm doing it wrong. In the spirit of this site I ask a specific question and beg for references.
