DESCRIPTION:We propose a scheme to investigate how motion through spacetim
 e affects entangle- ment. We find and compute the entanglement degradation
  analytically for a Dirichlet scalar field in a Minkowski cavity for traje
 ctories grafted from inertial and uniformly accelerated segments of small 
 acceleration\, giving explicit results for sample travel scenarios. Degrad
 ation of observable magnitude occurs for massless transverse quanta of opt
 ical wavelength at Earth gravity acceleration and for kaon mass quanta alr
 eady at microgravity acceleration. We outline a space-based experiment for
  observing the effect and its gravitational counterpart. We also find that
  entanglement between cavity modes can be created where none was present a
 nd\, for a particular trajectory and the two lowest modes\, (arbitrarily) 
 high two mode squeezing can be produced (Available as [1\, 2\, 3\, 4]).\n\
