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:

Cosmological Principle and Relativity - Part I (arxiv physics 0205033)
A relativistic time variation of matter/space fits both local and cosmic data (arxiv astro-ph 0208365)

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

12h	comment	Is antigravity the source of accelerating expansion (dark energy)? @Brandon : about the viability of the atom: Atomic orbital the energy is proportional to the average distance of the electronic orbital to the nucleus. Conjugate with the Bohr radius and we have to consider that the atom can scale without falling apart.
12h	comment	Is antigravity the source of accelerating expansion (dark energy)? @Brandon about orbitals: the Bohr radius distance between proton/electron in H scale as Length (Q-electron charge scale power 1,$h$ scale power 2, and fineStrCons is const ) in pag 10, table I.
12h	comment	Is antigravity the source of accelerating expansion (dark energy)? The theory was derived from two postulates and not from hypotheses: 1-in atomic units Length unit decreases with time; 2- all local and ﬁeld constants are time-independent. Change Mass: Charge changes -> change the spatial distribution of electronic charge. Do we know if mass scale is a volumetric property? or a surface property? or ? What is shown is that an equal rate of change in Mass/Length/Time unit gives a scaling universe and the basic equations of interactions electro/gravitic keep consistent (and all other physical equations also). Take your time to read the paper,pls.I need to rest.
13h	comment	Is antigravity the source of accelerating expansion (dark energy)? @Brandon ; I meant 'dimensionless' instead of the word 'constant'
13h	comment	Is antigravity the source of accelerating expansion (dark energy)? @Brandon: pag 10, table I, dimensionally fine structure y is a constant( for a M,L,T equal change) but Planck constant is not a constant. Bigger atoms -> larger electronic orbitals ,for equal $c$ more time is needed for a round trip equals a lower frequency.

May 10	comment	Andromeda is made of antimatter. Am I wrong? Why? from WP Interacting_galaxy: "Due to the extremely tenuous distribution of matter in galaxies, these are not collisions in the normal sense of the word, but rather gravitational interaction." Also on Earth the Northern hurricanes can not collide with the southern anti-hurricanes and both can exist.
May 6	comment	Does the amount of gravitational potential energy in the universe increase as it expands? my comment was addressed to all that in the last decades use free lunches in Physics. Since you depart from false premises then your article is also wrong. You will understand if you take some of your time to read the paper I've linked.
May 6	comment	Does the amount of gravitational potential energy in the universe increase as it expands? quoting from your paper: "This means that as the universe expands new energy is being created out of no where. " This is/should be unacceptable in physics. Read this pdf A self-similar model of the Universe unveils the nature of dark energy. DE is an artifact in the process of measuring.

May 3	comment	Relativistic origin of magnetic field @Val electron motion is slow motion Drift velocity. $\gamma$ =1 for non relativistics speeds. $v$ is the relative speed of the test charge in relation to the wire. 'motor' is irrelevant here. I edited my answer with the rainfall example.

Apr 25	comment	Cosmological redshift interpretation @Jim, then the atoms have to get bigger and a null measure of espansion should be the consequence. I posted my own answer to the original question.

Apr 25	answered	Cosmological redshift interpretation
Apr 25	comment	Cosmological redshift interpretation @Jim It is certain that 'space expansion' does not aplly locally, namely at Solar system scale, and a photon has to be considered local, I think. So, inserting 'space' between crests seems problematic.
