Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. When it comes to understanding the Universe, there are a few things ...

We consider Minkowski spacetime, the set of all point-events of spacetime under the relation of causal accessibility. That is, x can access y if an electromagnetic or (slower than light) mechanical ...

The seventh spacetime conference will commemorate the 115th anniversary of the publication (in 1909) of Minkowski's 1908 world-view-changing lecture "Space and Time," which presented the novel ideas ...

Minkowski spacetime has an origin, in order to make it vector space. The "central" event does not exist physically, origin is only for mathematical convenience. the tangent space at each event is a ...

In a previous paper we investigate a Lagrangian field theory for the gravitational field, which is there represented by a section {gα} of the coframe bundle over Minkowski spacetime (M≃R4,g̊,D̊,τg̊,↑) ...

ABSTRACT: Dramatic simplification of mathematical apparatus, special relativity’s hyperbolic versus circular versions, some equivalence of SR and Newton’s theories, algebra of relativistic and the ...
