Articles Relativity Physics

This is the category for articles in the field of relativity that deal not with the theory as a whole, but with selected aspects of relativistic physics.

• Are There Pictorial Examples of Covariant and Contravariant Vectors? - Present pictorial means of distinguishing contravariant vectors (or simply vectors) from covariant vectors (or linear forms). By Bernard Jancewicz (University of Wroclaw).
  
• Gravitomagnetic Effects - Introductory article by Gerhard Schäfer (Jena University) about the ways that rotating bodies affect spacetime (and hence the propagation of light and particles in free fall) in their vicinity.
  
• Inertia Manipulation Through Metric Patching - E-print which presents the exact solution for the stress-energy tensor of a spherical matter shell of finite thickness that will patch together different metrics at the boundaries of the shell. By David Waite.
  
• Solving Einstein's Equations in Three Dimensions - Mathematica notebook showing how to plot light cones in two plus one spacetime dimensions with a point mass. By Patricia Schwarz.
  
• Why Time is Absolute, and Relative, But Never Universal - Article by Vincent Sauvé elaborating upon a materialist view of the absolute and relative nature of time.
