Hi Fred,
thank you for that interesting question. I have seen an article on
the net, What
a Rindler Observer Sees in a Minkowski Vacuum, where the authors argue
that an observer accelerating relative to another observer has a different
vacuum state. They define the vacuum for an observer being the state in
which he sees no particles. The other observer accelerating relative to
the first one will actually see particles in that state. The vacuum state
depends on the observer. Observers moving at constant speed relative to
each other will see the same vacuum state.
Greetings
Michael
