Abstract: The knowledge of the Universe is essentially based on the theory of general relativity (GR). If from one hand, solar system data is in excellent agreement to the theory, available cosmological evidence on the other, is consistent with GR provided one assumes the existence of dark energy and dark matter.
The OPERA experiment recently announced surprising results: the speed of a beam of muon neutrinos was found to be higher than the speed of light, a 6-$sigma$ effect not easily discarded. It is not
the first time that faster-than-light (FTL) neutrinos haven been considered: they were proposed as an explanation (later ruled out) to observations of the supernova SN1987A, and the MINOS experiment has results similar to OPERA's.
Abstract: In this talk I will discuss ongoing work on using head on gravitational shock wave collisions in higher dimensional spacetimes to estimate the gravitational radiation emitted in transplanckian collisions.

Gr@v is a team of researchers, based at the Mathematics and Physics Department of Aveiro University, Portugal, working on strong gravity and high energy physics. The group was established in 2010. In January 2015 Gr@v integrated the FCT funded CIDMA research unit (UIDB/04106/2020 and UIDP/04106/2020), as the Gravitational Geometry and Dynamics research group. The group scientific coordinator is C. Herdeiro.
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
