Dear Georgina Parry,
Thank you for your kindly evaluation. I am glad that reading my essay was a pleasure for you. I have been a bit busy with changes in juanrga, including redesign of our site.
Let me emphasize that I only used the word "wrong" once and it was when referring to Laplace incorrect view of nature. When referring to the assumptions analysed I use other terms; indeed, the title of my essay is "Eight assumptions of modern physics which are not fundamental". I emphasize all this because it is directly related to your first question.
As explained in the essay the assumptions are not fundamental but obtained under a certain set of approximations. You can apply the assumptions within the limits of those approximations. Or said using other words, the previous theories are recovered as special limiting cases. There are no difficulties with explaining the observations made. As explained in the essay, if you consider a system for which the Lindblad operators are zero, the equation in section 3 reduces to the Schrödinger equation recovering ordinary quantum mechanics. In the section 7 it is explained how one recovers general relativity and so on.
The answer to your other question is "yes". I have a unified model of physics, chemistry, and biology. Not only we recover ordinary physics, from quantum field theory to cosmology, but many usual difficulties and puzzles are avoided. For instance, the cosmological problem is solved, the model gives a value for the CC in complete agreement with observations.
I will write papers about all of this and they will be announced in my site. I suppose that I could announce some here as well. Let me add that the theory is stochastic (which provides a fundamental framework for human free will), explains the arrow of time, and does unneeded fantasies such as Many-Worlds.
Now I am immersed in a matrix representation of the new formulation/interpretation of quantum mechanics announced above. I think I already found the needed mathematical technique (the Hilbert space is not enough and the mathematicians are still developing the Rigged extension) and I will start to write a paper about that.
Thank you again and good luck in the final round.
