The model I want to present here is a condensed matter or ether interpretation of the established modern field theory of particle physics, the Standard Model (SM) of particle physics. A popular presentation can be found at http://ilja-schmelzer.de/matter/ The model itself has been published in a peer-reviewed journal as I. Schmelzer, A condensed matter interpretation of SM fermions and gauge fields, Foundations of Physics, vol. 39, nr. 1, p. 73 (2009) and this paper can be downloaded frpm http://arxiv.org/abs/0908.0591 An improved version with some additional results about the masses have been published as I. Schmelzer, The Standard Model fermions as excitations of an ether, in: Reimer, A. (ed.), Horizons in World Physics, Volume 278, Nova Science Publishers (2012) and can be downloaded from http://arxiv.org/abs/0912.3892 What is the main point of this model? The SM is very well tested, and if one looks at it from point of view of its agreement with observation, everything is fine with the SM. But it has a weak point: It does not explain anything. It contains a lot of fields - three types of force fields (EM, strong and weak), where the strong contains 8 and the weak 3 field similar to the EM field, which already contains 6 components itself - and three generations of fermions, each generation containing a pair of leptons and three pairs of quarks, while each of these fermion fields contains 8 (4 complex) components. Each fermion has also charges for each of the three forces and masses. So, the SM is a quite complicate set of fields, and the SM does not give any hint why we have these fields, and not some others. This is what we observe, that's all the SM tells us. The ether model proposed here allows to explain this, based on a surprisingly simple model - a lattice of elementary cells, with some other material between them. The state of each cell is defined by a simple affine transformation from some reference cell, and such a transformation is a simple 3x(3+1) matrix. And this 3x(3+1) matrix is what we find in the SM too: Three generations, and in each generation one pair of leptons and three pairs of colored quarks.
