Bi-metric Universe with Matter
Carlos Maldonado, Fernando Mendez
We analyze the early stage of evolution of a universe with two scale factors proposed in [1] when matter is present. The scale factors describe two causally disconnected patches of…
The twin paradox: the role of acceleration
J. Gamboa, F. Mendez, M. B. Paranjape +1
The twin paradox, which evokes from the the idea that two twins may age differently because of their relative motion, has been studied and explained ever since it was first describ…
Time delay of light signals in an energy-dependent spacetime metric
A. F. Grillo, E. Luzio, F. Mendez
In this note we review the problem of time delay of photons propagating in a spacetime with a metric that explicitly depends on the energy of the particles (Gravity-Rainbow approac…
Modified Special Relativity on a fluctuating spacetime
R. Aloisio, A. Galante, A. F. Grillo +3
It was recently proposed that deformations of the relativistic symmetry, as those considered in Deformed Special Relativity (DSR), can be seen as the outcome of a measurement theor…
A note on DSR-like approach to space-time
R. Aloisio, A. Galante, A. F. Grillo +2
In this note we discuss the possibility to define a space-time with a DSR based approach. We show that the strategy of defining a non linear realization of the Lorentz symmetry wit…
