Probing time orientability of spacetime
N. A. Lemos, D. Müller, M. J. Reboucas
In general relativity, cosmology and quantum field theory, spacetime is assumed to be an orientable manifold endowed with a Lorentz metric that makes it spatially and temporally or…
Orientability of space from electromagnetic quantum fluctuations
N. A. Lemos, M. J. Reboucas
Whether the space where we live is a globally orientable manifold , and whether the local laws of physics require that be equipped with a canonical orientation, are amon…
Probing spatial orientability of Friedmann--Robertson--Walker spatially flat spacetime
N. A. Lemos, D. Müller, M. J. Reboucas
One important global topological property of a spacetime manifold is orientability. It is widely believed that spatial orientability can only be tested by global journeys around th…
Inquiring electromagnetic quantum fluctuations about the orientability of space
N. A. Lemos, M. J. Reboucas
Orientability is an important topological property of spacetime manifolds. It is generally assumed that a test for spatial orientability requires a journey across the whole 3-space…
The miniJPAS survey: a preview of the Universe in 56 colours
S. Bonoli, A. Marín-Franch, J. Varela +166
The Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) will soon start to scan thousands of square degrees of the northern extragalactic sky with a unique…
Violation of causality in gravity
G. Otalora, M. J. Reboucas
[Abridged] In its standard formulation, the field equations are not invariant under local Lorentz transformations, and thus the theory does not inherit the causal structure…
