Relativistic versus Newtonian Frames
2013
Positioning
Preserved Fulltext
Only a causal class among the 199 Lorentzian ones, which do not exists in the Newtonian space-time, is privileged to construct a generic, gravity free and immediate (non retarded) relativistic positioning ...
This is the causal class of the null emission coordinates. Emission coordinates are defined and generated by four emitters broadcasting their proper times. ...
This is related to the fact that, in Newtonian space-time, any set of space-like vectors always generates a space-like subspace. ...

In order to obtain the remaining two symmetries we need to apply the concept of the Killing vectors. A Killing vector ξ (x) is defined at each point in space time and thus constitutes a field. ...

In this paper, a system is proposed which can automatically generate 2+1D Minkowski diagrams. ...
Instead of treating space and time independently from each other, Minkowski connected them tightly in the form of a 4D spacetime and introduced spacetime diagrams as a new kind of visualization tool. ...
Space-time diagrams in textbooks can only show a static image of a fixed scenario and are very often limited to a 2D reduction of 4D spacetime with only one spatial axis. ...

With precision and scalability in mind, we propose a symmetric (non-causal) local time-window geometric integration scheme over temporal sequences, where shape reconstructions are refined framewise by ...

We study bubble collisions in this scenario and find that they generate gravity waves, which are made possible in this context by the reduced symmetry of the global geometry. ...
