Query: Minkowski and Special Relativity: Does His Spacetime Geometry Explain
  Space Contraction?   For over a century Minkowskian spacetime has dominated discussions of space
contraction and time dilation within special relativity. Brown and Pooley have
called into question both the assumptions of Minkowski and the effects his
presumed spacetime has upon objects in motion. But while they reject Minkowski,
Brown and Pooley do not fill in the missing causal connection between velocity
and space contraction and time dilation. To supply this causal connection
between object and observer in relative motion we should be focusing on energy
difference rather than velocity difference. When different inertial observers
at different relative velocities measure the same rod (or clock), each observer
registers a different amount of kinetic energy for the object. Following the
consequences of this permits a new understanding of relativistic space
contraction and time dilation.
