On the bispectrum of COBE and WMAP
João Magueijo, João Medeiros
The COBE-DMR 4-year maps displayed a strong non-Gaussian signal in the ``inter-scale'' components of the bispectrum: their observed values did not display the scatter expected from…
"Junk" DNA as a genetic decoy
Joao Magueijo
We propose that the evolutionary purpose of junk DNA is to protect the gene. Mutation agents, such as retro-viruses, hit ``decoy'' DNA most of the time. Although the argument is fa…
Varying Alpha and the Electroweak Model
Dagny Kimberly, Joao Magueijo
Inspired by recent claims for a varying fine structure constant, alpha, we investigate the effect of ``promoting coupling constants to variables'' upon various parameters of the st…
Neutrino mixing and Lorentz invariance
Massimo Blasone, Joao Magueijo, Paulo Pires-Pacheco
We use previous work on the Hilbert space for mixed fields to derive deformed dispersion relations for neutrino flavor states. We then discuss how these dispersion relations may be…
Gravity's Rainbow
Joao Magueijo, Lee Smolin
Non-linear special relativity (or doubly special relativity) is a simple framework for encoding properties of flat quantum space-time. In this paper we show how this formalism may…
New varying speed of light theories
Joao Magueijo
We review recent work on the possibility of a varying speed of light (VSL). We start by discussing the physical meaning of a varying , dispelling the myth that the constancy of…
Non-Linear Relativity in Position Space
Dagny Kimberly, João Magueijo, João Medeiros
We propose two methods for obtaining the dual of non-linear relativity as previously formulated in momentum space. In the first we allow for the (dual) position space to acquire a…
